How to write a business plan for an interior design consultancy?

Creating a business plan for an interior design consultancy is an essential process for any entrepreneur. It serves as a roadmap that outlines the necessary steps to be taken to start or grow the business, the resources required, and the anticipated financial outcomes. It should be crafted with method and confidence.
This guide is designed to provide you with the tools and knowledge necessary for creating an interior design consultancy business plan, covering why it is so important both when starting up and running an established business, what should be included in your plan, how it should be structured, what tools should be used to save time and avoid errors, and other helpful tips.
We have a lot to cover, so let's get to it!
Why write a business plan for an interior design consultancy?
Having a clear understanding of why you want to write a business plan for your interior design consultancy 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 an interior design consultancy 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 interior design consultancy. 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 interior design consultancy to be in the next three to five years.
Once you have a clear destination for your interior design consultancy, 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 get visibility on future cash flows
If your small interior design consultancy runs out of cash: it's game over. That's why we often say "cash is king", and it's crucial to have a clear view of your interior design consultancy's future cash flows.
So, how can you achieve this? It's simple - you need to have an up-to-date financial forecast.
The good news is that your interior design consultancy business plan already includes a financial forecast (which we'll discuss further in this guide). Your task is to ensure it stays current.
To accomplish this, it's essential to regularly compare your actual financial performance with what was planned in your financial forecast. Based on your business's current trajectory, you can make adjustments to the forecast.
By diligently monitoring your interior design consultancy's financial health, you'll be able to spot potential financial issues, like unexpected cash shortfalls, early on and take corrective actions. Moreover, this practice will enable you to recognize and capitalize on growth opportunities, such as excess cash flow enabling you to expand to new locations.
To secure financing
A detailed business plan becomes a crucial tool when seeking financing from banks or investors for your interior design consultancy.
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 interior design consultancy 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 interior design consultancy'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 interior design consultancy, let's explore what information is required to create a compelling plan.
Information needed to create a business plan for an interior design consultancy
Drafting an interior design consultancy 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 an interior design consultancy
Before you begin writing your business plan for an interior design consultancy, conducting market research is a critical step in ensuring precise and realistic financial projections.
Market research grants you valuable insights into your target customer base, competitors, pricing strategies, and other crucial factors that can impact the success of your business.
In the course of this research, you may stumble upon trends that could impact your interior design consultancy.
You may uncover that clients could be looking for more sustainable and environment-friendly home decor options. Additionally, market research could reveal that potential customers might be interested in interior design styles that are more contemporary and modern.
Such market trends play a pivotal role in revenue forecasting, as they provide essential data regarding potential customers' spending habits and preferences.
By integrating these findings into your financial projections, you can provide investors with more accurate information, enabling them to make well-informed decisions about investing in your interior design consultancy.
Developing the sales and marketing plan for an interior design consultancy
As you embark on creating your interior design consultancy 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 an interior design consultancy
Whether you are starting or expanding an interior design consultancy, 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 interior design consultancy may incur staffing costs such as salaries for interior designers, administrative staff, and other support staff. They may also incur costs for equipment, such as computers and furniture, and other materials, such as fabrics and wallpaper. Additionally, they may need to pay for software licenses and subscriptions to industry resources.
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 interior design consultancy, it is time to start creating your financial forecast.
What goes into your interior design consultancy's financial forecast?
The objective of the financial forecast of your interior design consultancy's business plan is to show the growth, profitability, funding requirements, and cash generation potential of your business over the next 3 to 5 years.
The four key outputs of a financial forecast for an interior design consultancy 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 an interior design consultancy shows how much revenue and profit your business is expected to make in the future.

A healthy interior design consultancy's P&L statement should show:
- Sales growing at (minimum) or above (better) inflation
- Stable (minimum) or expanding (better) profit margins
- A healthy level of net profitability
This will of course depend on the stage of your business: numbers for a startup will look different than for an established interior design consultancy.
The projected balance sheet of your interior design consultancy
Your interior design consultancy's forecasted balance sheet enables the reader of your plan to assess your financial structure, working capital, and investment policy.
It is composed of three types of elements: assets, liabilities and equity:
- Assets: represent what the business owns and uses to produce cash flows. It includes resources such as cash, equipment, and accounts receivable (money owed by clients).
- Liabilities: represent funds advanced to the business by lenders and other creditors. It includes items such as accounts payable (money owed to suppliers), taxes due and loans.
- Equity: is the combination of what has been invested by the business owners and the cumulative profits and losses generated by the business to date (which are called retained earnings). Equity is a proxy for the value of the owner's stake in the business.

Your interior design consultancy's balance sheet will usually be analyzed in conjunction with the other financial statements included in your forecast.
Two key points of focus will be:
- Your interior design consultancy's liquidity: does your business have sufficient cash and short-term assets to pay what it owes over the next 12 months?
- And its solvency: does your business have the capacity to repay its debt over the medium-term?
The cash flow forecast
As we've seen earlier in this guide, monitoring future cash flows is the key to success and the only way of ensuring that your interior design consultancy has enough cash to operate.
As you can expect showing future cash flows is the main role of the cash flow forecast in your interior design consultancy business plan.

It is best practice to organise the cash flow statement by nature in order to show the cash impact of the following areas:
- Cash flow generated from operations: the operating cash flow shows how much cash is generated or consumed by the business's commercial activities
- Cash flow from investing activities: the investing cash flow shows how much cash is being invested in capital expenditure (equipment, real estate, etc.) either to maintain the business's equipment or to expand its capabilities
- Cash flow from financing activities: the financing cash flow shows how much cash is raised or distributed to financiers
Looking at the cash flow forecast helps you to make sure that your business has enough cash to keep running, and can help you anticipate potential cash shortfalls.
Your interior design consultancy business plan will normally include both yearly and monthly cash flow forecasts 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 interior design consultancy 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 interior design consultancy, 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 interior design consultancy business plan, let's shift our focus to the written part of the plan.
The written part of an interior design consultancy business plan
The written part of an interior design consultancy 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
The first section of your interior design consultancy's business plan is the executive summary which provides, as its name suggests, an enticing summary of your plan which should hook the reader and make them want to know more about your business.
When writing the executive summary, it is important to provide an overview of the business, the market, the key financials, and what you are asking from the reader.
Start with a brief introduction of the business, its name, concept, location, how long it has been in operation, and what makes it unique. Mention any services or products you plan to offer and who you sell to.
Then you should follow with an overview of the addressable market for your interior design consultancy, current trends, and potential growth opportunities.
You should then include a summary of your key financial figures such as projected revenues, profits, and cash flows.
Finally, you should detail any funding requirements in the ask section.
2. The presentation of the company
As you build your interior design consultancy 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 interior design consultancy to a third party financier, you could mention that it is conveniently located in a thriving, metropolitan area. You might highlight the fact that it is a desirable location for potential customers, as well as being well-connected with excellent transportation links. You could also point out that the area is experiencing significant growth, and that there is a strong demand for interior design services in the region. All of these factors could demonstrate to the financier that your consultancy is well-placed to take advantage of a growing market.
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 interior design consultancy business plan should include a detailed description of what your company sells to its customers.
For example, your interior design consultancy might offer services such as space planning and layout, color and material selection, furniture and furnishings selection, and project management. These services help customers to create a space that meets their needs and aesthetic preferences. Furthermore, products such as furniture, fabrics, window treatments, lighting, and accessories can be sourced and supplied from suppliers, ensuring the customer's vision can be realized. Furthermore, services such as home styling can be provided, focusing on the placement of accessories and artwork to create the perfect atmosphere.
The reader will want to understand what makes your interior design consultancy unique from other businesses in this competitive market.
When drafting this section, you should be precise about the categories of products or services you sell, the clients you are targeting and the channels that you are targeting them through.
4. The market analysis
When you present your market analysis in your interior design consultancy 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 interior design consultancy, 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 interior design consultancy aims to serve and explaining how your products and services fulfil their distinct needs.
For example, your target market might include young professionals who are looking to furnish their first home. They have the disposable income to hire a professional interior designer, and they are eager to create a unique, personalized space. They are likely to be early adopters of design trends, and appreciate the value of an expert opinion.
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 interior design consultancy.
5. The strategy section
When writing the strategy section of a business plan for your interior design consultancy, it is essential to include information about your competitive edge, pricing strategy, sales & marketing plan, milestones, and risks and mitigants.
The competitive edge subsection should explain what sets your company apart from its competitors. This part is especially key if you are writing the business plan of a startup, as you have to make a name for yourself in the marketplace against established players.
The pricing strategy subsection should demonstrate how you intend to remain profitable while still offering competitive prices to your customers.
The sales & marketing plan should outline how you intend to reach out and acquire new customers, as well as retain existing ones with loyalty programs or special offers.
The milestones subsection should outline what your company has achieved to date, and its main objectives for the years to come - along with dates so that everyone involved has clear expectations of when progress can be expected.
The risks and mitigants subsection should list the main risks that jeopardize the execution of your plan and explain what measures you have taken to minimize these. This is essential in order for investors or lenders to feel secure in investing in your venture.
Your interior design consultancy faces a variety of risks to the success of its operations. For example, you could encounter financial risk due to the cost of materials, labor, and other expenses associated with the projects you take on. Your business may also be vulnerable to contractual risks, in which clients could fail to pay for services or breach the agreement in some other way. Strict compliance with local, state, and federal regulations may also be necessary to ensure the success of your business.
6. The operations section
The operations of your interior design consultancy 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 interior design consultancy'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.
Your interior design consultancy may have key assets such as its portfolio of designs, as well as any intellectual property (IP) related to the company’s brand and logo. The portfolio might showcase the consultancy’s best work, and the IP could help to add value to the company and create an identity that’s recognizable in the industry. Additionally, the consultancy might also have key assets such as its network of suppliers, contacts, and clients, which could help to secure future business opportunities.
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 an interior design consultancy business plan, let's look at some of the tools you can use to create yours.
What tool should I use to write my interior design consultancy's business plan?
There are two main ways of creating your interior design consultancy business plan:
- Using specialized business planning software,
- Hiring a business plan writer.
Using an online business plan software for your interior design consultancy's business plan
Using online business planning software is the most efficient and modern way to write an interior design consultancy business plan.
There are several advantages to using specialized software:
- You can easily create your financial forecast by letting the software take care of the financial calculations for you without errors
- You are guided through the writing process by detailed instructions and examples for each part of the plan
- You can access a library of dozens of complete business plan samples and templates for inspiration
- You get a professional business plan, formatted and ready to be sent to your bank or investors
- You can easily track your actual financial performance against your financial forecast
- You can create scenarios to stress test your forecast's main assumptions
- You can easily update your forecast as time goes by to maintain visibility on future cash flows
- You have a friendly support team on standby to assist you when you are stuck

Hiring a business plan writer to write your interior design consultancy's business plan
Outsourcing your interior design consultancy 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 interior design consultancy 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 interior design consultancy's business plan using Word or Excel?
Using Microsoft Excel and Word (or their Google, Apple, or open-source equivalents) to write an interior design consultancy business plan is a terrible idea.
Why?
For starters, creating an accurate and error-free financial forecast on Excel (or any spreadsheet) is very technical and requires both a strong grasp of accounting principles and solid skills in financial modelling.
As a result, it is unlikely anyone will trust your numbers unless - like us at The Business Plan Shop - you hold a degree in finance and accounting and have significant financial modelling experience in your past.
The second reason is that it is inefficient. Building forecasts on spreadsheets was the only option in the 1990s and early 2000s, nowadays technology has advanced and software can do it much faster and much more accurately.
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.
Also, using software makes it easy to compare actuals vs. forecasts and maintain our forecasts up to date to maintain visibility on future cash flows - as we discussed earlier in this guide - whereas this is a pain to do with a spreadsheet.
That's for the forecast, but what about the written part of my interior design consultancy business plan?
This part is less error-prone, but here also software brings tremendous gains in productivity:
- Word processors don't include instructions and examples for each part of your business plan
- Word processors don't update your numbers automatically when they change in your forecast
- Word processors don't handle the formatting for you
- ...
Overall, while Word or Excel may be viable options for creating an interior design consultancy business plan for some entrepreneurs, it is by far not the best or most efficient solution.
Takeaways
- Using business plan software is a modern and cost-effective way of writing and maintaining business plans.
- A business plan is not a one-shot exercise as maintaining it current is the only way to keep visibility on your future cash flows.
- A business plan has 2 main parts: a financial forecast outlining the funding requirements of your interior design consultancy and the expected growth, profits and cash flows for the next 3 to 5 years; and a written part which gives the reader the information needed to decide if they believe the forecast is achievable.
We hope that this in-depth guide met your expectations and that you now have a clear understanding of how to write your interior design consultancy business plan. Do not hesitate to contact our friendly team if you have questions additional questions we haven't addressed here.
