How to write a business plan for a private investigation agency?

Putting together a business plan for a private investigation agency can be daunting - especially if you're creating a business for the first time - but with this comprehensive guide, you'll have the necessary tools to do it confidently.
We will explore why writing one is so important in both starting up and growing an existing private investigation agency, as well as what should go into making an effective plan - from its structure to content - and what tools can be used to streamline the process and avoid errors.
Without further ado, let us begin!
Why write a business plan for a private investigation agency?
Having a clear understanding of why you want to write a business plan for your private investigation agency will make it simpler for you to grasp the rationale behind its structure and content. So before delving into the plan's actual details, let's take a moment to remind ourselves of the primary reasons why you'd want to create a private investigation agency business plan.
To have a clear roadmap to grow the business
Small businesses rarely experience a constant and predictable environment. Economic cycles go up and down, while the business landscape is mutating constantly with new regulations, technologies, competitors, and consumer behaviours emerging when we least expect it.
In this dynamic context, it's essential to have a clear roadmap for your private investigation agency. Otherwise, you are navigating in the dark which is dangerous given that - as a business owner - your capital is at risk.
That's why crafting a well-thought-out business plan is crucial to ensure the long-term success and sustainability of your venture.
To create an effective business plan, you'll need to take a step-by-step approach. First, you'll have to assess your current position (if you're already in business), and then identify where you'd like your private investigation agency to be in the next three to five years.
Once you have a clear destination for your private investigation agency, you'll focus on three key areas:
- Resources: you'll determine the human, equipment, and capital resources needed to reach your goals successfully.
- Speed: you'll establish the optimal pace at which your business needs to grow if it is to meet its objectives within the desired timeframe.
- Risks: you'll identify and address potential risks you might encounter along the way.
By going through this process regularly, you'll be able to make informed decisions about resource allocation, paving the way for the long-term success of your business.
To anticipate future cash flows
Regularly comparing your actual financial performance to the projections in the financial forecast of your private investigation agency's business plan gives you the ability to monitor your business's financial health and make necessary adjustments as needed.
This practice allows you to detect potential financial issues, such as unexpected cash shortfalls before they escalate into major problems. Giving you time to find additional financing or put in place corrective measures.
Additionally, it helps you identify growth opportunities, like excess cash flow that could be allocated to launch new products and services or expand into new markets.
Staying on track with these regular comparisons enables you to make well-informed decisions about the amount of financing your business might require, or the excess cash flow you can expect to generate from your main business activities.
To secure financing
A detailed business plan becomes a crucial tool when seeking financing from banks or investors for your private investigation agency.
Investing and lending to small businesses are very risky activities given how fragile they are. Therefore, financiers have to take extra precautions before putting their capital at risk.
At a minimum, financiers will want to ensure that you have a clear roadmap and a solid understanding of your future cash flows (like we just explained above). But they will also want to ensure that your business plan fits the risk/reward profile they seek.
This will off-course vary from bank to bank and investor to investor, but as a rule of thumb. Banks will want to see a conservative financial management style (low risk), and they will use the information in your business plan to assess your borrowing capacity — the level of debt they think your business can comfortably handle — and your ability to repay the loan. This evaluation will determine whether they'll provide credit to your private investigation agency and the terms of the agreement.
Whereas investors will carefully analyze your business plan to gauge the potential return on their investment. Their focus lies on evidence indicating your private investigation agency's potential for high growth, profitability, and consistent cash flow generation over time.
Now that you recognize the importance of creating a business plan for your private investigation agency, let's explore what information is required to create a compelling plan.

Information needed to create a business plan for a private investigation agency
Drafting a private investigation agency business plan requires research so that you can project sales, investments and cost accurately in your financial forecast, and convince the reader that there is a viable commercial opportunity to be seized.
Below, we'll focus on three critical pieces of information you should gather before starting to write your plan.
Carrying out market research for a private investigation agency
As you consider writing your business plan for a private investigation agency, conducting market research becomes a vital step to ensure accurate and realistic financial projections.
Market research provides valuable insights into your target customer base, competitors, pricing strategies, and other key factors that can significantly impact the commercial success of your business.
Through this research, you may uncover trends that could influence your private investigation agency.
You may discover that more people are seeking out private investigation services as a preventative measure, such as to vet potential employees or partners. Additionally, you might find that more people are looking for private investigation services for personal reasons, such as to confirm suspicions of infidelity or to investigate fraud.
Such market trends play a significant role in forecasting revenue, as they offer valuable data about potential customers' spending habits and preferences.
By incorporating these findings into your financial projections, you can present investors with more accurate information, helping them make informed decisions about investing in your private investigation agency.
Developing the sales and marketing plan for a private investigation agency
As you embark on creating your private investigation agency business plan, it is crucial to budget sales and marketing expenses beforehand.
A well-defined sales and marketing plan should include precise projections of the actions required to acquire and retain customers. It will also outline the necessary workforce to execute these initiatives and the budget required for promotions, advertising, and other marketing efforts.
This approach ensures that the appropriate amount of resources is allocated to these activities, aligning with the sales and growth objectives outlined in your business plan.
The staffing and capital expenditure requirements of a private investigation agency
Whether you are starting or expanding a private investigation agency, it is important to have a clear plan for recruitment and capital expenditures (investment in equipment and real estate) in order to ensure the success of the business.
Both the recruitment and investment plans need to be coherent with the timing and level of growth planned in your forecast, and require appropriate funding.
A private investigation agency might incur staffing costs such as salaries for investigators and support staff, as well as costs for benefits such as health insurance and retirement plans. Additionally, they may need to purchase equipment such as computers, cameras, audio recording devices, and other investigative tools.
In order to create a realistic financial forecast, you will also need to consider the other operating expenses associated with running the business on a day-to-day basis (insurance, bookkeeping, etc.).
Once you have all the necessary information to create a business plan for your private investigation agency, it is time to start creating your financial forecast.
What goes into your private investigation agency's financial forecast?
The financial forecast of your private investigation agency's business plan will enable you to assess the growth, profitability, funding requirements, and cash generation potential of your business in the coming years.
The four key outputs of a financial forecast for a private investigation agency are:
- The profit and loss (P&L) statement,
- The projected balance sheet,
- The cash flow forecast,
- And the sources and uses table.
Let's look at each of these in a bit more detail.
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.

Ideally, your private investigation agency's P&L statement should show:
- Healthy growth - above inflation level
- Improving or stable profit margins
- Positive net profit
Expectations will vary based on the stage of your business. A startup will be expected to grow faster than an established private investigation agency. And similarly, an established company should showcase a higher level of profitability than a new venture.
The forecasted balance sheet of your private investigation agency
The projected balance sheet of your private investigation agency will enable the reader of your business plan to assess the overall financial health of your business.
It shows three elements: assets, liabilities and equity:
- Assets: are productive resources owned by the business, such as equipment, cash, and accounts receivable (money owed by clients).
- Liabilities: are debts owed to creditors, lenders, and other entities, such as accounts payable (money owed to suppliers).
- Equity: includes the sums invested by the shareholders or business owners and the profits and losses accumulated by the business to date (which are called retained earnings). It is a proxy for the value of the owner's stake in the business.

Analysing your private investigation agency projected balance sheet provides an understanding of your private investigation agency's working capital structure, investment and financing policies.
In particular, the readers of your plan can compare the level of financial debt on the balance sheet to the equity value to measure the level of financial risk (equity doesn't need to be reimbursed, while financial debt must be repaid, making it riskier).
They can also use your balance sheet to assess your private investigation agency's liquidity and solvency:
- A liquidity analysis: focuses on whether or not your business has sufficient cash and short-term assets to cover its liabilities due in the next 12 months.
- A solvency analysis: takes and longer view to assess whether or not your business has the capacity to repay its debts over the medium-term.
The projected cash flow statement
A cash flow forecast for a private investigation agency shows how much cash the business is projected to generate or consume.

The cash flow statement is divided into 3 main areas:
- The operating cash flow shows how much cash is generated or consumed by the operations (running the business)
- The investing cash flow shows how much cash is being invested in capital expenditure (equipment, real estate, etc.)
- The financing cash flow shows how much cash is raised or distributed to investors and lenders
Looking at the cash flow forecast helps you to ensure that your business has enough cash to keep running, and can help you anticipate potential cash shortfalls.
It is also a best practice to include a monthly cash flow statement in the appendices of your private investigation agency business plan so that the readers can view the impact of seasonality on your business cash position and generation.
The initial financing plan
The initial financing plan, also known as a sources and uses table, is a valuable resource to have in your business plan when starting your private investigation agency as it reveals the origins of the money needed to establish the business (sources) and how it will be allocated (uses).

Having this table helps show what costs are involved in setting up your private investigation agency, how risks are shared between founders, investors and lenders, and what the starting cash position will be. This cash position needs to be sufficient to sustain operations until the business reaches a break-even point.
Now that you have a clear understanding of what goes into the financial forecast of your private investigation agency business plan, let's shift our focus to the written part of the plan.

The Business Plan Shop has dozens of business plan templates that you can use to get a clear idea of what a complete business plan looks like.

The written part of a private investigation agency business plan
The written part of a private investigation agency business plan is composed of 7 main sections:
- The executive summary
- The presentation of the company
- The products and services
- The market analysis
- The strategy
- The operations
- The financial plan
Throughout these sections, you will seek to provide the reader with the details and context needed for them to form a view on whether or not your business plan is achievable and your forecast a realistic possibility.
Let's go through the content of each section in more detail!
1. The executive summary
In your private investigation agency's business plan, the first section is the executive summary — a captivating overview of your plan that aims to pique the reader's interest and leave them eager to learn more about your business.
When crafting the executive summary, start with an introduction to your business, including its name, concept, location, how long it has been running, and what sets it apart. Briefly mention the products and services you plan to offer and your target customer profile.
Following that, provide an overview of the addressable market for your private investigation agency, current trends, and potential growth opportunities.
Next, include a summary of key financial figures like projected revenues, profits, and cash flows.
Finally, in the "ask" section, detail any funding requirements you may have.
2. The presentation of the company
As you build your private investigation agency business plan, the second section deserves attention as it delves into the structure and ownership, location, and management team of your company.
In the structure and ownership part, you'll provide valuable insights into the legal structure of the business, the identities of the owners, and their respective investments and ownership stakes. This level of transparency is vital, particularly if you're seeking financing, as it clarifies which legal entity will receive the funds and who holds the reins of the business.
Moving to the location part, you'll offer a comprehensive view of the company's premises and articulate why this specific location is strategic for the business, emphasizing factors like catchment area, accessibility, and nearby amenities.
When describing the location of your private investigation agency, you may want to emphasize its accessibility and appeal. You could talk about its proximity to major highways, public transportation, and airports, which could make it easy for clients to access your services. You might also mention the area's vibrant culture and potential for growth, which could be attractive to potential investors. Finally, you could discuss the availability of resources in the area that could help you run your business, such as technology hubs, coworking spaces, and networking opportunities.
Lastly, you should introduce your esteemed management team. Provide a thorough explanation of each member's role, background, and extensive experience.
It's equally important to highlight any past successes the management team has achieved and underscore the duration they've been working together. This information will instil trust in potential lenders or investors, showcasing the strength and expertise of your leadership team and their ability to deliver the business plan.
3. The products and services section
The products and services section of your business plan should include a detailed description of what your company offers, who are the target customers, and what distribution channels are part of your go-to-market.
For example, your private investigation agency might offer surveillance to assess a person's activity, background checks to ensure that a potential hire is trustworthy, and asset searches to locate hidden assets. These services enable customers to gain information that they may not be able to obtain on their own, such as finding out who they are associating with, the truth about someone's background, or locating hidden assets.
4. The market analysis
When you present your market analysis in your private investigation agency business plan, it's crucial to include detailed information about customers' demographics and segmentation, target market, competition, barriers to entry, and any relevant regulations.
The main objective of this section is to help the reader understand the size and attractiveness of the market while demonstrating your solid understanding of the industry.
Begin with the demographics and segmentation subsection, providing an overview of the addressable market for your private investigation agency, the key trends in the marketplace, and introducing different customer segments along with their preferences in terms of purchasing habits and budgets.
Next, focus on your target market, zooming in on the specific customer segments your private investigation agency aims to serve and explaining how your products and services fulfil their distinct needs.
For example, your target market might include corporate executives needing background checks on potential employees. This market is especially important for companies in the technology or financial industries that need to protect valuable data. Additionally, the private investigation agency might target individuals who need assistance with legal matters, such as uncovering evidence for a divorce or finding a missing person.
Then proceed to the competition subsection, where you introduce your main competitors and highlight what sets you apart from them.
Finally, conclude your market analysis with an overview of the key regulations applicable to your private investigation agency.
5. The strategy section
When you write the strategy section of your private investigation agency business plan, remember to cover key elements such as your competitive edge, pricing strategy, sales & marketing plan, milestones, and risks and mitigants.
In the competitive edge subsection, elaborate on what makes your company stand out from competitors. This becomes especially important if you're a startup, aiming to carve a place for yourself amidst established players in the marketplace.
The pricing strategy subsection should demonstrate how you plan to maintain profitability while offering competitive prices to attract customers.
Outline your sales & marketing plan, detailing how you'll reach out to new customers and retain existing ones through loyalty programs or special offers.
For the milestones subsection, outline your company's achievements to date and your main objectives for the future, complete with specific dates to set clear expectations for progress.
Lastly, the risks and mitigants subsection should address the main risks that could affect your plan's execution. Explain the measures you've put in place to minimize these risks, assuring potential investors or lenders.
Your private investigation agency faces a variety of risks everyday. You could be exposed to financial or legal risks if a client disputes the findings of your investigations. You might also face reputational risks if client confidentiality is breached or if information is shared without the client's consent. To mitigate these risks, it is important to have a clear understanding of the laws and regulations related to private investigation and to have appropriate policies and procedures in place.
6. The operations section
The operations of your private investigation agency must be presented in detail in your business plan.
Begin by addressing your staff, specifying the main roles and your recruitment plan to support the anticipated growth. Outline the qualifications and experience needed for each role and discuss your recruitment strategies, which may involve using job boards, referrals, or headhunters.
Next, clearly state your private investigation agency's operating hours, allowing the reader to gauge the adequacy of your staffing levels. Additionally, mention any considerations for varying opening times during peak seasons and your approach to handling customer queries outside regular operating hours.
The key assets and intellectual property (IP) required to run your business should also be highlighted. If you rely on licenses, trademarks, physical structures like equipment or property, or lease agreements, ensure they are well-documented in this section.
You may have certain key assets and IP that are important to your private investigation agency. For example, you could have access to confidential databases such as criminal records and public records which may be used to gather information on suspects or other parties. Additionally, you might have private investigators that have worked in the industry for years and have the expertise and skill to conduct investigations efficiently and effectively.
Finally, provide a comprehensive list of suppliers you intend to collaborate with, along with a breakdown of their services and main commercial terms, such as price, payment terms, break clauses and contract duration. Investors often seek insight into the reasons behind your supplier choices, which may include a preference for higher-quality products or established relationships from past ventures.
7. The presentation of the financial plan
The financial plan section is where we will include the financial forecast we talked about earlier in this guide.
Now that you have a clear idea of the content of a private investigation agency business plan, let's look at some of the tools you can use to create yours.
What tool should I use to write my private investigation agency's business plan?
In this section, we will be reviewing the two main options for writing a private investigation agency business plan efficiently:
- Using specialized software,
- Outsourcing the drafting to the business plan writer.
Using an online business plan software for your private investigation agency's business plan

Hiring a business plan writer to write your private investigation agency's business plan
Outsourcing your private investigation agency business plan to a business plan writer can also be a viable option.
Business plan writers are experienced in writing business plans and adept at creating financial forecasts without errors. Furthermore, hiring a consultant can save you time and allow you to focus on the day-to-day operations of your business.
However, hiring business plan writers is expensive as you are paying for the software used by the consultant, plus their time, and their profit margin of course.
From experience, you need to budget at least £1.5k ($2.0k) excluding tax for a complete business plan, more if you need to make changes after the initial version (which happens frequently after the initial meetings with lenders or investors).
You also need to be careful when seeking investment. Investors want their money to be used to grow the business, not spent on consulting fees. Therefore, the amount you spend on business plan writing services (and other consulting services such as legal services) needs to be negligible relative to the amount raised.
The other drawback is that you usually don't own the business plan itself: you just get the output, while the actual document is saved in the consultant's business plan software - which makes it difficult to maintain the document up to date without hiring the consultant on a retainer.
For these reasons, outsourcing the private investigation agency business plan to a business plan writer should be considered carefully, weighing both the advantages and disadvantages of hiring outside help.
Ultimately, it may be the right decision for some businesses, while others may find it beneficial to write their business plan using online software.
Why not create your private investigation agency's business plan using Word or Excel?
I must advise against using Microsoft Excel and Word (or their Google, Apple, or open-source equivalents) to write your private investigation agency business plan. Let me explain why.
Firstly, creating an accurate and error-free financial forecast on Excel (or any spreadsheet) is highly technical and requires a strong grasp of accounting principles and financial modelling skills. It is, therefore, unlikely that anyone will fully trust your numbers unless you have both a degree in finance and accounting and significant financial modelling experience, like us at The Business Plan Shop.
Secondly, relying on spreadsheets is inefficient. While it may have been the only option in the past, technology has advanced significantly, and software can now perform these tasks much faster and with greater accuracy. With the rise of AI, software can even help us detect mistakes in forecasts and analyze the numbers for better decision-making.
And with the rise of AI, software is also becoming smarter at helping us detect mistakes in our forecasts and helping us analyse the numbers to make better decisions.
Moreover, software makes it easier to compare actuals versus forecasts and maintain up-to-date forecasts to keep visibility on future cash flows, as we discussed earlier in this guide. This task is cumbersome when using spreadsheets.
Now, let's talk about the written part of your private investigation agency business plan. While it may be less error-prone, using software can bring tremendous gains in productivity. Word processors, for example, lack instructions and examples for each part of your business plan. They also won't automatically update your numbers when changes occur in your forecast, and they don't handle formatting for you.
Overall, while Word or Excel may seem viable for some entrepreneurs to create a business plan, it's by far becoming an antiquated way of doing things.
Takeaways
- A business plan has 2 complementary parts: a financial forecast showcasing the expected growth, profits and cash flows of the business; and a written part which provides the context needed to judge if the forecast is realistic and relevant.
- Having an up-to-date business plan is the only way to keep visibility on your private investigation agency's future cash flows.
- Using business plan software is the modern way of writing and maintaining business plans.
