How to create a financial forecast for an advertising agency?

If you are serious about keeping visibility on your future cash flows, then you need to build and maintain a financial forecast for your advertising agency.
Putting together an advertising agency financial forecast may sound complex, but don’t worry, with the right tool, it’s easier than it looks, and The Business Plan Shop is here to guide you.
In this practical guide, we'll cover everything you need to know about building financial projections for your advertising agency.
We will start by looking at why they are key, what information is needed, what a forecast looks like once completed, and what solutions you can use to create yours.
Let's dive in!
Why create and maintain a financial forecast for an advertising agency?
In order to prosper, your business needs to have visibility on what lies ahead and the right financial resources to grow. This is where having a financial forecast for your advertising agency becomes handy.
Creating an advertising agency financial forecast forces you to take stock of where your business stands and where you want it to go.
Once you have clarity on the destination, you will need to draw up a plan to get there and assess what it means in terms of future profitability and cash flows for your advertising agency.
Having this clear plan in place will give you the confidence needed to move forward with your business’s development.
Having an up-to-date financial forecast for an advertising agency is also useful if your trading environment worsens, as the forecast enables you to adjust to your new market conditions and anticipate any potential cash shortfall.
Finally, your advertising agency's financial projections will also help you secure financing, as banks and investors alike will want to see accurate projections before agreeing to finance your business.

What information is used as input to build an advertising agency financial forecast?
A advertising agency's financial forecast is only as good as the inputs used to build it.
If you are creating (or updating) the forecast of an existing advertising agency, then you mostly need your accounting information, key historical operating non-financial data, and your team’s input on what to expect for the coming years.
If you are building financial projections for an advertising agency startup, you will need to have done your research and have a clear picture of your competitive environment and go-to-market strategy so that you can forecast sales accurately.
For a new venture, you will also need a precise list of the resources needed to keep the advertising agency running on a day-to-day basis and a list of the equipment and expenditures required to start the business (more on that later).
Let's now take a closer look at the elements that make up your advertising agency's financial forecast.
The sales forecast for an advertising agency
The sales forecast, also called topline projection, is normally where you will start when building your advertising agency financial forecast.
Creating a coherent sales projection boils down to estimating two key drivers:
- The average price
- The number of monthly transactions
To do this, you will need to rely on historical data (for an existing business), market research data (for both new and existing advertising agencies), and consider the elements below:
- Economic Conditions: The state of the economy can greatly impact the average price and number of transactions for your advertising agency. During a recession, businesses may have less disposable income to spend on advertising, resulting in a decrease in the average price. Similarly, a strong economy may lead to an increase in the average price as businesses have more money to invest in advertising.
- Competition: The level of competition in your industry can also affect your sales forecast. If there are many other advertising agencies offering similar services at lower prices, you may need to lower your average price to remain competitive. On the other hand, if you have a unique selling proposition or a niche market, you may be able to charge a higher average price.
- Technological Advancements: With the constant advancements in technology, your clients may have different needs and expectations for your services. This can lead to changes in the average price and number of transactions for your agency. For example, the rise of social media has resulted in a higher demand for digital advertising, which may increase your average price for these services.
- Client Retention: The loyalty and satisfaction of your clients can also play a role in your sales forecast. If you have a high retention rate and consistently provide quality services, you may be able to maintain or increase your average price. However, if you struggle with retaining clients, you may need to lower your prices to attract new business.
- Industry Trends: Keeping up with industry trends and changes can also impact your sales forecast. For example, if there is a shift towards a certain type of advertising (e.g. influencer marketing), you may need to adapt your services and pricing to stay relevant and competitive.
After the sales forecast comes the operating expenses budget, which we will now look into in more detail.

The operating expenses for an advertising agency
The next step is to estimate the costs you’ll have to incur to operate your advertising agency.
These will vary based on where your business is located, and its overall size (level of sales, personnel, etc.).
But your advertising agency's operating expenses should normally include the following items:
- Staff costs: This includes salaries, benefits, and taxes for all employees at your advertising agency.
- Accountancy fees: You may need to hire an accountant to help with financial planning, tax preparation, and other financial services.
- Insurance costs: You will need various insurance policies to protect your agency, employees, and clients, such as liability insurance, property insurance, and workers' compensation insurance.
- Software licenses: As an advertising agency, you will need to invest in software licenses for programs such as graphic design software, project management tools, and marketing automation software.
- Banking fees: Your agency will likely have multiple bank accounts for managing client payments, payroll, and other financial transactions, which will incur banking fees.
- Rent and utilities: You will need office space to run your agency, which will come with rent and utility costs, such as electricity, water, and internet.
- Marketing and advertising expenses: To promote your agency and attract clients, you will need to invest in marketing and advertising, such as social media ads, print ads, and event sponsorships.
- Travel expenses: Depending on your client base, you may need to travel for meetings, presentations, and events, which will incur travel expenses such as airfare, hotel stays, and meals.
- Professional development: As an advertising agency, it is essential to stay updated on industry trends and skills. You may need to invest in professional development opportunities for yourself and your employees.
- Office supplies: Running an agency will require various office supplies, such as stationery, printer ink, and other supplies.
- Telephone and internet expenses: You will need to have communication tools in place for your agency, such as telephone and internet services, which will come with monthly expenses.
- Client entertainment: Building and maintaining relationships with clients is crucial for an advertising agency. You may need to entertain clients, which will come with expenses such as meals and event tickets.
- Legal fees: Your agency may need legal services, such as contract reviews or trademark registrations, which will incur legal fees.
- Office equipment: You will need various office equipment, such as computers, printers, and office furniture, to run your agency.
- Employee benefits: In addition to salaries, you may offer employee benefits such as health insurance, retirement plans, and paid time off, which will come with expenses.
This list is not exhaustive by any means, and will need to be tailored to your advertising agency's specific circumstances.
What investments are needed to start or grow an advertising agency?
Your advertising agency financial forecast will also need to include the capital expenditures (aka investments in plain English) and initial working capital items required for the creation or development of your business.
For an advertising agency, these could include:
- Office Space: This includes the cost of renting or leasing a physical office space for the agency. This may also include the cost of utilities, maintenance, and any necessary renovations or improvements.
- Furniture and Equipment: This includes the cost of purchasing office furniture, such as desks, chairs, and filing cabinets, as well as any necessary equipment for the agency, such as computers, printers, and telephones.
- Software and Technology: This includes the cost of purchasing and maintaining necessary software and technology for the agency, such as project management software, design software, and communication tools.
- Vehicles: This includes the cost of purchasing and maintaining any vehicles that are used for business purposes, such as company cars or delivery vans.
- Advertising Materials: This includes the cost of purchasing and producing advertising materials, such as brochures, business cards, and promotional items, as well as any necessary printing or production equipment.
Again, this list will need to be adjusted according to the size and ambitions of your advertising agency.

The financing plan of your advertising agency
The next step in the creation of your financial forecast for your advertising agency is to think about how you might finance your business.
You will have to assess how much capital will come from shareholders (equity) and how much can be secured through banks.
Bank loans will have to be modelled so that you can separate the interest expenses from the repayments of principal, and include all this data in your forecast.
Issuing share capital and obtaining a bank loan are two of the most common ways that entrepreneurs finance their businesses.
What tables compose the financial plan for an advertising agency?
Now let's have a look at the main output tables of your advertising agency's financial forecast.
The projected profit & loss statement
The projected profit & loss shows how profitable your advertising agency is likely to be in the years to come.

For your advertising agency to be financially viable, your projected P&L should ideally show:
- Sales growing above inflation (the higher the better)
- Profit margins which are stable or expanding (the higher the better)
- A net profit at the end of each financial year (the higher the better)
This is for established advertising agencies, there is some leniency for startups which will have numbers that will look a bit different than existing businesses.
The projected balance sheet
Your advertising agency's forecasted balance sheet enables you to assess your financial structure and working capital requirements.
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.

The cash flow projection
The cash flow forecast of your advertising agency will show how much cash the business is expected to generate or consume over the next three to five years.

There are multiple ways of presenting a cash flow forecast but from experience, it is better to organise it by nature in order to clearly show these elements:
- Operating cash flow: how much cash is generated by the advertising agency's operations
- Investing cash flow: what is the business investing to expand or maintain its equipment
- Financing cash flow: is the business raising additional funds or repaying financiers (debt repayment, dividends)
Your cash flow forecast is the most important element of your overall financial projection and that’s where you should focus your attention to ensure that your advertising agency is adequately funded.
Note: if you are preparing a financial forecast in order to try to secure funding, you will need to include both a yearly and monthly cash flow forecast in your advertising agency's financial plan.

Which tool should you use to create your advertising agency's financial forecast?
Creating your advertising agency's financial forecast may sound fairly daunting, but the good news is that there are several ways to go about it.
Using online financial forecasting software to build your advertising agency's projections
The modern and easiest way 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
- You can easily track your actual financial performance against your financial forecast, and recalibrate your forecast as the year goes by
- 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
- It’s cost-efficient and much cheaper than using an accountant or consultant (see below)
If you are interested in this type of solution, you can try our forecasting software for free by signing up here.
Calling in a financial consultant or chartered accountant
Outsourcing the creation of your advertising agency financial forecast is another possible solution.
This will cost more than using software as you can expect as your price will have to cover the accountant’s time, software cost, and profit margin.
Price can vary greatly based on the complexity of your business. For a small business, from experience, a simple three-year financial forecast (including a balance sheet, income statement, and cash flow statement) will start at around £700 or $1,000.
Bear in mind that this is for forecasts produced at a single point in time, updating or tracking your forecast against actuals will cost extra.
If you decide to outsource your forecasting:
- Make sure the professional has direct experience in your industry and is able to challenge your assumptions constructively.
- Steer away from consultants using sectorial ratios to build their client’s financial forecasts (these projections are worthless for a small business).
Why not use a spreadsheet such as Excel or Google Sheets to build your advertising agency's financial forecast?
You and your financial partners need numbers you can trust. Unless you have studied finance or accounting, creating a trustworthy and error-free advertising agency financial forecast on a spreadsheet is likely to prove challenging.
Financial modelling is very technical by nature and requires a solid grasp of accounting principles to be done without errors. This means that using spreadsheet software like Excel or Google Sheets to create accurate financial forecasts is out of reach for most business owners.
Creating forecasts in Excel is also inefficient nowadays:
- Software has advanced to the point where forecasting can be done much faster and more accurately than manually on a spreadsheet.
- With artificial intelligence, the software is capable of detecting mistakes and helping decision-making.
Spreadsheets are versatile tools but they are not tailor-made for reporting. Importing your advertising agency's accounting data in Excel to track actual vs. forecast is incredibly manual and tedious (and so is keeping forecasts up to date). It is much faster to use dedicated financial planning tools like The Business Plan Shop which are built specially for this.
