Ready to kickstart your entrepreneurial journey? Let's begin!
Understanding how a private investigation agency works
The very first step when exploring a business idea such as starting a private investigation agency is to make sure you understand how the business operates and makes money (which is what we call the business model).
This will not only give you an initial idea of how profitable the business can be, but it will also enable you to make sure that this is the right business idea for you, given your skills, start-up capital and family or personal lifestyle, in particular.
The best ways to get to grips with the private investigation agency's business model are to:
- Talk to private investigation agency owners with experience
- Work a few months in a private investigation agency already in operation
- Take a training course
Talk to private investigation agency owners with experience
Experienced private investigation agency owners have valuable insights and can provide practical advice based on their firsthand experiences.
They've likely encountered and overcome challenges that a newcomer might not anticipate. Learning from other’s mistakes can save you both time and money and potentially increase your venture’s chances of succeeding.
Work a few months in a private investigation agency already in operation
Obtaining work experience in the industry can be a crucial factor in confirming whether you truly want to start a private investigation agency, as it provides insight into the day-to-day activities.
For instance, if the working hours are longer than expected or if other business requirements don't align with your personal lifestyle or preferences, you might reconsider your entrepreneurial goals.
Even if you've decided that this business idea is a good fit for you, gaining work experience will still be valuable. It helps you better understand your target market and customer needs, which is likely to be beneficial when launching your own private investigation agency.
Take a training course
Obtaining training within your chosen industry is another way to get a feel for how a private investigation agency works before deciding to pursue a new venture.
Whatever approach you choose to familiarise yourself with the business, before going any further with your plans to open a private investigation agency, make sure you understand:
- What skills are required to run the business (compare this with your own skills)
- What a typical week in the business is like (compare this with your personal or family life)
- What is the potential turnover of a private investigation agency and the long-term growth prospects (compare this with your level of ambition)
- Your options once you decide to sell the business or retire (it's never too early to consider your exit)
Can your business idea be profitable?
Just enter your data and let The Business Plan Shop crunch the numbers. We will tell if your business idea can generate profits and cash flows, and how much you need to get started.

What is the ideal founding team for my private investigation agency?
The next step to opening your private investigation agency, is to decide whether to assemble an ideal team or venture solo.
The failure rate for business start-ups is high: almost half don't make it past the five-year mark, and setting up a private investigation agency is no exception.
Starting with a group of co-founders helps reduce this risk as each of you brings complementary skills and enables the financial risk to be spread on multiple shoulders.
However, managing a business with multiple partners comes with its own set of challenges. Disagreements among co-founders are quite prevalent, and they can pose risks to the business. That's why it's essential to carefully weigh all aspects before launching a business.
To help you think things through, we recommend that you ask yourself the following questions:
- Do you need more co-founders for this venture?
- Do you share the same vision and ambition as your potential partners for this project?
- What is your plan B?
Let's look at these issues in more detail.
Do you need more co-founders for this venture?
To answer this question you will need to consider the following:
- Are there any key skills missing for which you would rather have a business partner than recruit an employee?
- Do we have enough equity? Would the company benefit from more capital at the outset?
- Will the proposed number of founders make it easy to make decisions (an odd number of partners, or a majority partner, is generally recommended to avoid deadlock)?
In simple terms, co-founders bring skills, money, or both to the table. Having more partners is beneficial when there's a lack of either of these resources.
Do you share the same vision and ambition as your potential partners for this project?
One of the main sources of conflict between co-founders comes from a lack of alignment on the long-term vision.
To avoid any risk of disagreement, it is advisable to agree on ambitions from the outset and to provide an exit mechanism for one of the partners in the event of disagreement.
What is your plan B?
We hope your private investigation agency takes off and thrives, but it's smart to have a "plan B" just in case things don't go as expected.
How you tackle potential failure can vary broadly depending on the type of co-founders (close friend, spouse, ex-colleague, etc.) and the personal circumstances of each of them.
For example, launching a family business with your spouse might seem exciting, but if it fails, you risk losing all of your household income at once, which might be stressful.
Likewise, starting a business with a friend might strain the friendship if things go wrong or if tough decisions need to be made.
Before diving in, make sure to thoroughly think about your choices. This way, you'll be ready for whatever might come your way when starting up.
Is there room for another private investigation agency on the market?
The next step in starting a private investigation agency is to undertake market research. Now, let's delve into what this entails.
The objectives of market research
The goal here is straightforward: evaluate the demand for your business and determine if there's an opportunity to be seized.
One of the key points of your market analysis will be to ensure that the market is not saturated by competing offers.
The market research to open your private investigation agency will also help you to define a concept and market positioning likely to appeal to your target clientele.
Finally, your analysis will provide you with the data you need to assess the revenue potential of your future business.
Let's take a look at how to carry out your market research.
Evaluating key trends in the sector
Market research for a private investigation agency usually begins with an analysis of the sector in order to develop a solid understanding of its key players, and recent trends.
Assessing the demand
After the sector analysis comes demand analysis. Demand for a private investigation agency refers to customers likely to consume the products and services offered by your company or its competitors.
Looking at the demand will enable you to gain insights into the desires and needs expressed by your future customers and their observed purchasing habits.
To be relevant, your demand analysis must be targeted to the geographic area(s) served by your company.
Your demand analysis should highlight the following points:
- Who buys the type of products and services you sell?
- How many potential customers are there in the geographical area(s) targeted by your company?
- What are their needs and expectations?
- What are their purchasing habits?
- How much do they spend on average?
- What are the main customer segments and their characteristics?
- How to communicate and promote the company's offer to reach each segment?
Analyzing demand helps pinpoint customer segments your private investigation agency could target and determines the products or services that will meet their expectations.
Assessing the supply
Once you have a clear vision of who your potential customers are and what they want, the next step is to look at your competitors.
Amongst other things, you’ll need to ask yourself:
- What brands are competing directly/indirectly against your private investigation agency?
- How many competitors are there in the market?
- Where are they located in relation to your company's location?
- What will be the balance of power between you and your competitors?
- What types of services and products do they offer? At what price?
- Are they targeting the same customers as you?
- How do they promote themselves?
- Which concepts seem to appeal most to customers?
- Which competitors seem to be doing best?
The aim of your competitive analysis will be to identify who is likely to overshadow you, and to find a way to differentiate yourself (more on this see below).
Regulations
Market research is also an opportunity to look at the regulations and conditions required to do business.
Ask yourself the following questions:
- Do you need a special degree to open a private investigation agency?
- Are there necessary licences or permits?
- What are the main laws applicable to your future business?
At this stage, your analysis of the regulations should be carried out at a high level, to familiarize yourself with any rules and procedures, and above all to ensure that you meet the necessary conditions for carrying out the activity before going any further.
You will have the opportunity to come back to the regulation afterwards with your lawyer when your project is at a more advanced stage.
Take stock of the lessons learned from your market analysis
Market research should give you a definitive idea of your business idea's chances of commercial success.
Ideally, the conclusion is that there is a market opportunity because one or more customer segments are currently underserved by the competition.
On the other hand, the conclusion may be that the market is already taken. In this case, don't panic: the first piece of good news is that you're not going to spend several years working hard on a project that has no chance of succeeding. The second is that there's no shortage of ideas out there: at The Business Plan Shop, we've identified over 1,300 business start-up ideas, so you're bound to find something that will work.

The Business Plan Shop makes it easy to create a financial forecast and write a business plan to help convince investors that your business idea can be profitable.

How should I position my private investigation agency on the market?
The next step to start your private investigation agency is to define precisely the market positioning your company will adopt in order to capitalise on the opportunity identified during your market research.
Market positioning refers to the place your product and service offering occupies in customers' minds and how they differ from the competition. Being perceived as a low-cost solution, for example.
To find a concept and a market positioning that will resonate with your customers, you need to address the following issues:
- How can you differentiate yourself from your competitors?
- Is it better to start or buy a private investigation agency already in operation?
- How will you validate your concept and market positioning before investing in the business?
Let's look at these aspects in more detail.
How can you differentiate yourself from your competitors?
Opening a private investigation agency means starting with a major disadvantage compared with competitors already active on the market.
While you will have to create everything from scratch, your competitors already have everything in place.
Your competitors' teams know the business well, whereas yours has only just been recruited, their customers are loyal and they benefit from word of mouth that you don't yet have.
So you're going to need a solid plan to succeed in taking market share from your competitors and making your mark.
There are a number of aspects to consider in order to try to avoid direct confrontation if possible:
- Can you target a different customer base than your competitors?
- Can you offer products or services that are different from or complementary to what your competitors already sell?
- How will your competitors react to your private investigation agency entering their market?
- Can you build a sustainable competitive advantage that will enable you to compete with your current and future competitors?
Is it better to start or buy a private investigation agency already in operation?
The alternative to setting up a new independent business is to buy out and take over a private investigation agency already in operation.
A takeover is a good way of reducing the risk of your project compared with a pure start-up.
Taking over a business has two enormous advantages over setting up a new one: you start out on an equal footing with your competitors since you take over the team and the customer base, and you don't increase the supply on the market enabling you to maintain the existing balance on the market where the business operates.
However, the capital requirements for a takeover are higher because the business will have to be bought from its previous owners.
How will you validate your concept and market positioning before investing in the business?
However you decide to set up your business, you will need to ensure that there is a good fit between what you sell and what customers are looking to buy.
To do this, you'll need to meet your target customers to present your products or services and check that they meet their expectations.
Deciding where to base your private investigation agency
The next step to opening a private investigation agency is deciding where you want to set up your business.
Choosing the right location for your business is like finding the perfect stage for a play. Without it, your business may lack the spotlight it deserves.
Whilst there is no “perfect” location for your private investigation agency, one that meets as many of the following factors as possible could be ideal:
This list is obviously not exhaustive and will have to be adapted to the particularities of your project.
Once you’ve considered the factors above, it’s important to think about the budget that your startup has at its disposal. You’ll need to find a location that meets your business requirements but is affordable enough, especially short-term.
If you opt for renting instead of buying your premises, make sure to take into account the terms of the lease, including aspects such as the duration, rent increase, renewal, and so on.
The lease contractual terms vary greatly from country to country, so be sure to check the terms applicable to your situation and have your lease reviewed by your lawyer before signing.

What legal form should I choose for my private investigation agency?
The next step to start a private investigation agency is to choose the legal form of your business.
The legal form of a business simply means the legal structure it operates under. This structure outlines how the business is set up and defines its legal obligations and responsibilities.
Why is your private investigation agency's legal form important?
Choosing the right legal form for your private investigation agency is important because this will affect:
- Taxation: your tax obligations depend on the legal structure you choose, and this principle applies to both personal income tax and business taxes.
- Risk exposure: some legal structures have a legal personality (also known as corporate personality) and limited liability, which separates them from the owners running the business. This means that the business would be liable rather than the owners if things were to go wrong (lawsuit, debt owed in case of bankruptcy, etc.).
- Decision-making and governance: how you make key decisions varies based on the legal form of your business. In some cases you might need to have a board of directors and organise general assemblies to enable shareholders to influence major decisions with their voting rights.
- Financing: securing funding from investors requires you to have a company and they will expect limited liability and corporate personality to protect them legally.
- Paperwork and legal formalities: the legal structure you select determines whether certain obligations are necessary, such as producing annual accounts, or getting your books audited.
Popular business legal forms
The specific names of legal structures vary from country to country, but they usually fall within the two main categories below:
- Individual businesses
- Companies
Individual businesses
Individual businesses, like sole traders or sole proprietorships, are made for self-employed entrepreneurs and freelancers rather than businesses which employ staff.
They benefit from straightforward administrative requirements, minimal paperwork to start, simpler tax calculations, and streamlined accounting procedures.
However, the downside is that there's typically no legal distinction between the business and the person responsible for day-to-day operations. This means the owner's personal assets are at risk if the business faces problems or goes bankrupt.
There is also no share capital in such a structure, meaning that individual businesses cannot raise equity from investors which seriously limits funding options.
Companies
Companies are versatile structures suited to projects of all sizes in terms of number of founders, number of employees and amount of capital.
They are a bit more complex to operate than individual businesses with more formalities, stringent accounting requirements, more complex tax implications, etc.
In return, they offer stronger protections to their shareholders. They usually benefit from having their own legal identity and limited liability, meaning co-founders and investors can only ever lose the amount of money they have put into the company.
For instance, if things were to go south (the company files for bankruptcy or there is a legal issue), the company would take the hit, safeguarding the personal assets of the founders and investors.
How should I choose my private investigation agency's legal structure?
Deciding on a legal form is easy once you've estimated your sales, decided whether or not you need employees and figured out the number of co-founders joining you.
It's essential to remember that a solid business idea will succeed no matter which legal structure you pick. Tax laws change regularly, so you can't rely on specific tax advantages tied to a particular structure when starting a business.
A proven approach is to look at what legal structures your top competitors are using, and go with the most common option as a working assumption. Once your idea is mature enough, and you're getting closer to officially registering your business, you can get advice from a lawyer and an accountant to confirm your choice.
Can I switch my private investigation agency's legal structure if I get it wrong?
Yes, changing your legal structure later is possible, though it may involve selling the old entity to a new entity in some cases, which adds further expenses. If you want to save on such costs, it makes sense to pick the correct legal form for your business the first time around.
Can your business idea be profitable?

Assess the startup costs for a private investigation agency
The next step in creating a private investigation agency involves thinking about the equipment and staff needed for the business to operate.
After figuring out what you need for your business, your financial plan will reveal how much money you'll need to start and how much you might make (check below for more details).
Because every venture is distinctive, providing a reliable one-size-fits-all budget for launching a private investigation agency without knowing the specifics of your project is not feasible.
Each project has its own particularities (size, concept, location), and only a forecast can show the exact amount required for the initial investment.
The first thing you'll need to consider is the equipment and investments you'll need to get your business up and running.
Startup costs and investments to launch your private investigation agency
For a private investigation agency, the initial working capital requirements (WCR) and investments could include the following elements:
- Surveillance equipment: This may include cameras, recording devices, and other specialized equipment used for surveillance operations.
- Vehicle fleet: Private investigation agencies often require a fleet of vehicles for conducting investigations and transporting investigators to various locations.
- Computer hardware and software: Private investigation agencies need computers, laptops, and other equipment to store and analyze data, as well as specialized software for conducting investigations.
- Office equipment: This may include printers, scanners, fax machines, and other equipment necessary for day-to-day operations in the agency's office.
- Security systems: Private investigation agencies may invest in security systems for their office and storage facilities to protect sensitive information and equipment.
Of course, you will need to adapt this list to your business specificities.
Staffing plan of a private investigation agency
In addition to equipment, you'll also need to consider the human resources required to run the private investigation agency on a day-to-day basis.
The number of recruitments you need to plan will depend mainly on the size of your company.
Once again, this list is only indicative and will need to be adjusted according to the specifics of your private investigation agency.
Other operating expenses for a private investigation agency
While you're thinking about the resources you'll need, it's also a good time to start listing the operating costs you'll need to anticipate for your business.
The main operating costs for a private investigation agency may include:
- Staff Costs: This includes salaries, wages, and benefits for your private investigators, administrative staff, and other employees. You may also need to budget for training and development expenses.
- Accountancy Fees: As a private investigation agency, you may need to hire an accountant or bookkeeper to manage your financial records and prepare tax returns.
- Insurance Costs: You will need to budget for various types of insurance, including professional liability insurance, general liability insurance, and workers' compensation insurance.
- Software Licences: You may need to purchase licenses for investigative software programs, such as case management software or forensic analysis tools.
- Banking Fees: This includes fees for maintaining business bank accounts, processing credit card payments, and other financial transactions.
- Rent and Utilities: If you have a physical office space, you will need to budget for rent, utilities, and other facility expenses.
- Marketing and Advertising: You may need to allocate funds for marketing and advertising efforts to promote your private investigation agency and attract new clients.
- Travel Expenses: Private investigators may need to travel for investigations or to attend court hearings. You will need to budget for transportation, lodging, and other related expenses.
- Equipment and Supplies: This includes expenses for purchasing and maintaining investigative equipment, such as cameras, recording devices, and forensic tools.
- Professional Memberships: You may need to join professional associations or obtain certifications, which may come with membership fees and other related costs.
- Legal Fees: As a private investigation agency, you may need to consult with lawyers for legal advice or representation. You will need to budget for legal fees and court costs.
- Consulting Services: You may need to hire outside consultants or experts for specific investigations or to provide specialized services for your agency.
- Office Supplies: You will need to budget for everyday office supplies, such as paper, pens, and printer ink.
- Telephone and Internet Expenses: You will need to budget for monthly phone and internet bills for your office and any mobile devices used by your investigators.
- Employee Benefits: In addition to salaries, you may need to budget for employee benefits, such as health insurance, retirement plans, and paid time off.
Like for the other examples included in this guide, this list will need to be tailored to your business but should be a good starting point for your budget.
Creating a sales & marketing plan for your private investigation agency
The next step to start a private investigation agency is to think about how you are going to attract and retain customers.
You need to ask yourself the following questions:
- What actions can be leveraged to attract as many customers as possible?
- How will you then retain customers?
- What resources do you need to allocate for each initiative (human and financial)?
- How many sales and what turnover can you expect to generate in return?
How you will attract and retain customers depends on your ambition, the size of your startup and the nature of your exact concept, but you could consider the following initiatives.
Your sales forecast may also be influenced by seasonality related to your business type, such as fluctuations during busy holiday periods, and your competitive environment.

Building your private investigation agency's financial forecast
The next step to opening a private investigation agency is to create your financial forecast.
What is a private investigation agency financial forecast?
A private investigation agency financial forecast is a forward-looking tool that projects the financial performance of your business over a specific period (usually 3 years for start-ups).
A forecast looks at your business finances in detail - from income to operating costs and investments - to evaluate its expected profitability and future cash flows.
Building a financial forecast enables you to determine the precise amount of initial financing required to start your private investigation agency.
There are many promising business ideas but very few are actually viable and making a financial forecast is the only way to ensure that your project holds up economically and financially.

Your financial forecast will also be part of your overall business plan (which we will detail in a later step), which is the document you will need to secure financing.
Financial forecasts are used to drive your private investigation agency and make key decisions, both in the pre and post-launch phases:
- Should we go ahead with the business or scrap the idea?
- Should we hire staff or use an external service provider?
- Which development project offers the best growth prospects?
- Etc.
Creating a financial forecast for starting a private investigation agency is an iterative process as you will need to refine your numbers as your business idea matures.
As your private investigation agency grows, your forecasts will become more accurate. You will also need to test different scenarios to ensure that your business model holds true even if economic conditions deteriorate (lower sales than expected, difficulties in recruiting, sudden cost increases or equipment failure problems, for example).
Once you’ve launched your business, it will also be important to regularly compare your accounting data to your financial projections in order to keep your forecast up-to-date and maintain visibility on future cash flows.
What does a financial projection look like?
Your private investigation agency forecast will be presented using the following financial tables.
The projected P&L statement
The projected P&L statement for a private investigation agency shows how much revenue and profits your business is expected to generate in the future.

The projected balance sheet of your private investigation agency
Your private investigation agency's projected balance sheet provides a snapshot of your business’s financial position at year-end.

The cash flow forecast
A projected cash flow statement for a private investigation agency is used to show how much cash the business is expected to consume or generate in the years to come.

What is the best financial forecasting tool for starting your private investigation agency?
The simplest and easiest way to create your private investigation agency's projections is to use professional online financial forecasting software such as the one we offer at The Business Plan Shop.
There are several advantages to using specialised software:
- You can easily create your financial forecast by letting the software take care of the financial calculations for you without errors
- You have access to complete financial forecast templates
- You get a complete financial forecast ready to be sent to your bank or investors
- The software helps you identify and correct any inconsistencies in your figures
- You can create scenarios to stress-test your forecast's main assumptions to stress-test the robustness of your business model
- After you start trading, you can easily track your actual financial performance against your financial forecast, and recalibrate your forecast to maintain visibility on your future cash flows
- You have a friendly support team on standby to assist you when you are stuck

Finding a name and registering your private investigation agency
The next step in starting a private investigation agency is to decide on a name for your entity.
For starters, you cannot take a name similar to a name already registered by a competitor or protected by a trademark without inevitably risking getting sued. So you’ll need to find a name available, and reserve it before others can.
In addition, you will probably want to use the same name for:
- Your company’s legal name - Example LTD or Example Inc
- Your trading name - Example
- A trademark - Example ®
- Your company’s domain name - Example.com
The issue is that you’ll need to register your name in three different places almost simultaneously, but with each place having its own timeframes:
- Registering a domain name is instantaneous
- Registering a trademark takes at least 3 months (if your application is accepted)
- Registering a company depends on the country, but it's generally fairly quick
You will therefore be faced with the choice of either registering everything at once in the hope that your name will be accepted everywhere, or proceeding step by step in order to minimise costs, but taking the risk that someone else will register one of the names you wanted in the meantime.
Our advice is to discuss the strategy with your legal counsel (see further down in this guide) and to give priority to your domain names and your registered trademark. You'll always have the option of using a trading name that's different from your company's legal name, and that's not a big deal.
To check that the name you want is not already in use, you should consult:
- Your country's business register
- The register of trademarks where you wish to obtain protection
- Your preferred search engine
- A domain name reservation company (such as GoDaddy)
If the name you want is available, you can go ahead and register it.

Develop your private investigation agency's corporate identity
The next step to launching a private investigation agency: defining your company's visual identity.
Your corporate identity defines how your company's values are communicated visually. It makes you unique and allows you to stand out visually from your competitors and be recognized by your customers.
Defining your corporate identity can easily be done by you and your co-founders, using the many free tools available to generate color palettes, logos and other graphic elements. Nevertheless, this task is often best entrusted to a designer or agency to achieve a professional result.
Your private investigation agency's visual identity will include the following elements:
- Logo
- Brand guidelines
- Business cards
- Website theme
Logo
The goal is to have stakeholders identify your business logo quickly and relate to it. Your logo will be used for media purposes (website, social networks, business cards, etc.) and legal documents (invoices, contracts, etc.).
The design of your logo must be emblematic, but it's also important that it can be seen on any type of support. To achieve this, it should be easily available in a range of colors, so that it stands out on both light and dark backgrounds.
Brand guidelines
The brand guidelines of your private investigation agency act as a safeguard to ensure that your image is consistent whatever the medium used.
Brand guidelines lay out the details like the typography and colors to use to represent your company.
Typography refers to the fonts used (family and size). For example, Arial in size 26 for your titles and Tahoma in size 15 for your texts.
When it comes to the colors representing your brand, it's generally a good idea to stick to five or fewer:
- The main colour,
- A secondary colour (the accent),
- A dark background colour (blue or black),
- A grey background colour (to vary from white),
- Possibly another secondary colour.
Business cards
A rare paper medium that continues to survive digitalization, business cards are still a must-have for communicating your private investigation agency contact details to your customers, suppliers and other partners.
In principle, they will include your logo and the brand guidelines we mentioned above.
Website theme
Likewise, the theme of your private investigation agency website will include your logo and follow the brand guidelines we discussed earlier.
This will also define the look and feel of the main visual elements on your website:
- Buttons
- Menus
- Forms
- Banners
- Etc.
Navigate the legal and regulatory requirements for launching your private investigation agency
The next thing to do in getting a private investigation agency off the ground is to handle all the legal and regulatory requirements. We recommend that you be accompanied by a law firm for all of the steps outlined below.
Intellectual property
One of your priorities will be to ensure that your company's intellectual property is adequately protected.
As explained before, you can choose to register a trademark. Your lawyer can help you with a detailed search to make sure your chosen trademark is unique and doesn't clash with existing ones.
They'll assist in preparing the required documents and steer you in picking the right categories and locations for trademark registration.
Moreover, your lawyer can offer guidance on additional measures to protect other intellectual property assets your company may have.
Getting your private investigation agency paperwork in order
For day-to-day operations, your private investigation agency will need to rely on a set of contractual documents.
Your exact needs in this respect will depend on the country in which you are launching your private investigation agency, the number of partners and the envisaged size of the company.
However, you will probably need at least the following documents:
- Employment contracts
- General terms and conditions of sale
- General terms and conditions of use for your website
- Privacy Policy for your website
- Cookie Policy for your website
- Invoices
- Etc.
Applying for licences and permits and registering for various taxes
Operating your business legally may require licences and business permits. The exact requirements applicable to your situation will depend on the country in which you set up your private investigation agency.
The lawyers who advise you will also be able to guide you with regard to all the rules applicable to your business.
Similarly, your accountant will be able to help you take the necessary steps to comply with the tax authorities.

Create a business plan for your private investigation agency
The next step to open a private investigation agency: put together your business plan.
What is a business plan?
To keep it simple, a business plan comprises two crucial components:
- Firstly, a numerical part, the financial forecast (which we mentioned earlier), which highlights the initial financing requirements and profitability potential of the private investigation agency,
- And a written, well-argued section that presents your project in detail, aims to convince the reader of its chances of success, and provides the context needed to assess whether the forecast is realistic or not.
The business plan will enable you to verify the coherence of your project, and ensure that the company can be profitable before incurring further costs. It will also help you convince business and financial partners.
As you can see, your business plan must be convincing and error-free.

Raise the financing needed to launch your private investigation agency
With your business plan in hand, you can tackle one of the final steps to open a private investigation agency business: the search for financing.
Raising the capital needed to launch your business will probably require a combination of equity and debt, which are the two types of financing available to companies.
Equity funding
Equity is the sum of money invested in a private investigation agency by both founders and investors.
Equity is a key factor in business start-ups. Should the project fail, the sums invested in equity are likely to be lost; these sums therefore enable the founders to send a strong signal to their commercial and financial partners as to their conviction in the project's chances of success.
In terms of return on investment, equity investors can either receive dividends from the company (provided it is profitable) or realize capital gains by selling their shares (provided a buyer is interested in the company).
Equity providers are therefore in a very risky position. They can lose everything in the event of bankruptcy, and will only see a return on their investment if the company is profitable or resold. On the other hand, they can generate a very high return if the project is a success.
Given their position, equity investors look for start-up projects with sufficient growth and profitability potential to offset their risk.
From a technical standpoint, equity includes:
- Share capital and premiums: which represent the amount invested by the shareholders. This capital is considered permanent as it is non-refundable. In return for their investment, shareholders receive shares that entitle them to information, decision-making power (voting in general assembly), and the potential to receive a portion of any dividends distributed by the company.
- Director loans: these are examples of non-permanent capital advanced to the company by the shareholders. This is a more flexible way of injecting some liquidity into your company as you can repay director loans at any time.
- Reserves: these represent the share of profits set aside to strengthen the company's equity. Allocating a percentage of your profits to the reserves can be mandatory in certain cases (legal or statutory requirement depending on the legal form of your company). Once allocated in reserves, these profits can no longer be distributed as dividends.
- Investment grants: which represent any non-refundable amounts received by the company to help it invest in long-term assets.
- Other equity: which includes the equity items which don't fit in the other categories. Mostly convertible or derivative instruments. For a small business, it is likely that you won't have any other equity items.
The main sources of equity are as follows:
- Contributions made by the owners.
- Private investors: business angels, friends and family.
- Crowdfunding: raising funds by involving a group of people through campaigns where they contribute money or make donations, often getting something in return for their support.
- Start-up aid, e.g. government loans to help founders build up their start-up capital.
Debt financing
Debt is the other way of financing companies. Unlike equity, debt offers lenders a limited, contractually guaranteed return on their investment.
Your private investigation agency undertakes to pay lenders' interest and repay the capital borrowed according to a pre-agreed schedule. Lenders are therefore making money whether or not your company makes a profit.
As a result, the only risk lenders take is that of your private investigation agency going bankrupt, so they're extremely conservative and will want to see prudent, hands-on management of the company's finances.
From the point of view of the company and all its stakeholders (workforce, customers, suppliers, etc.), the company's contractual obligation to repay lenders increases the risk for all. As a result, there is a certain caution towards companies which are too heavily indebted.
Businesses can borrow debt in two main ways:
- Against assets: this is the most common way of borrowing. The bank funds a percentage of the price of an asset (a vehicle or a building, for example) and takes the asset as collateral. If the business cannot repay the loan, the bank takes the asset and sells it to reduce losses.
- Against cash flows: the bank looks at how much profit and cash flow the business expects to make in the future. Based on these projections, it assigns a credit risk to the business and decides how much the business can borrow and under what terms (amount, interest rate, and duration of the loan).
It's difficult to borrow against future cash flows when you're starting a private investigation agency, because the business doesn't yet have historical data to reassure about the credibility of cash flow forecast.
Borrowing to finance a portion of equipment purchases is therefore often the only option available to founders. The assets that can be financed with this option must also be easy to resell, in the unfortunate event that the bank is forced to seize them, which could limit your options even further.
As far as possible sources of borrowing are concerned, the main ones here are banks and credit institutions. Bear in mind, however, that each institution is different, in terms of the risk it is prepared to accept, what it is willing to finance, and how the risk of your project will be perceived.
In some countries, it is also possible to borrow from private investors (directly or via crowdfunding platforms) or other companies, but not everywhere.
Key points about financing your private investigation agency
Multiple solutions are available to help you raise the initial financing you need to open your private investigation agency. A minimum amount of equity will be needed to give the project credibility, and bank financing can be sought to complete the financing.
What to do after launching my private investigation agency?
Launching your private investigation agency is the beginning of an exciting entrepreneurial adventure, and the culmination of your efforts to turn your idea into a reality. But this is also when the real work begins.
As you know, nearly half of all new businesses fail, so you'll need to do everything you can to make your business sustainable right from the start.
Estimating the future financial performance of a private investigation agency inevitably involves a degree of uncertainty. That's why we recommend simulating several scenarios: a central case with the most likely scenario, an optimistic case, and a pessimistic case designed to test the limits of your business model.
Normally, your company's actual financial performance, observed after you start trading, should fall somewhere between your pessimistic and optimistic cases.
The important thing will be to quickly measure and compare this actual performance with the figures in your forecast to see where you stand, then update the forecast to re-estimate the future cash flows and cash position of your private investigation agency.
This forward-looking financial management exercise is the only way to know where you stand and where you're going. And, when your figures fall short of expectations, to quickly implement actions to turn things around before the company runs out of cash.
There's nothing more dangerous than waiting until you have your accounts, which takes up to nine months after the end of your financial year (if you are in the UK, abroad your mileage will vary), to then realize that you're not on the right track and that your private investigation agency won't have enough cash to operate over the next twelve months.
This is where using a forecasting solution that integrates actuals vs. forecast tracking, like The Business Plan Shop's financial dashboards do, can simplify the financial management of your business and help reduce the risk associated with your start-up project.
