How to create a financial forecast for an e-commerce store?

Creating a financial forecast for your e-commerce store, and ensuring it stays up to date, is the only way to maintain visibility on future cash flows.
This might sound complex, but with the right guidance and tools, creating an accurate financial forecast for your e-commerce store is not that hard.
In this guide, we'll cover everything from the main goal of a financial projection, the data you need as input, to the tables that compose it, and the tools that can help you build a forecast efficiently.
Without further ado, let us begin!
Why create and maintain a financial forecast for an e-commerce store?
The financial projections for your e-commerce store act as a financial blueprint to guide its growth with confidence and ensure its long-term financial viability.
To create them, you will need to look at your business in detail - from sales to operating costs and investments - to assess how much profit it can generate in the years to come and what will be the associated cash flows.
During challenging market conditions, maintaining an up-to-date financial forecast enables early detection of potential financial shortfalls, allowing for timely adjustments or securing financing before facing a cash crisis.
Your e-commerce store's financial forecast will also prove invaluable when seeking financing. Banks and investors will undoubtedly request a thorough examination of your financial figures, making precision and presentation essential.

What information is used as input to build an e-commerce store financial forecast?
A e-commerce store'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 e-commerce store, 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 e-commerce store 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 e-commerce store 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 e-commerce store's financial forecast.
The sales forecast for an e-commerce store
From experience, it is usually best to start creating your e-commerce store financial forecast by your sales forecast.
To create an accurate sales forecast for your e-commerce store, you will have to rely on the data collected in your market research, or if you're running an existing e-commerce store, the historical data of the business, to estimate two key variables:
- The average price
- The number of monthly transactions
To get there, you will need to consider the following factors:
- Seasonal trends: As an e-commerce store, your sales may be affected by seasonal trends. For example, during the holiday season, you may experience a surge in sales due to increased consumer spending.
- Trends in consumer behavior: Changes in consumer behavior can impact your average price and number of monthly transactions. For instance, if there is a shift towards more sustainable or ethical shopping, you may need to adjust your prices or product offerings accordingly.
- Economic conditions: Economic conditions such as inflation, unemployment, and interest rates can influence consumer spending and, in turn, your sales. A strong economy may lead to higher average prices and more transactions, while a weak economy may have the opposite effect.
- Competition: The level of competition in your industry can also affect your sales. If you have a lot of competitors offering similar products at lower prices, you may need to adjust your prices to remain competitive and maintain your average price and number of transactions.
- Product popularity: The popularity of your products can have a significant impact on your sales. If you have a highly sought-after product, you may be able to charge a higher price and see an increase in transactions. On the other hand, if your products are not in demand, you may need to lower your prices to attract customers.
Once you have an idea of what your future sales will look like, it will be time to work on your overhead budget. Let’s see what this entails.

The operating expenses for an e-commerce store
The next step is to estimate the expenses needed to run your e-commerce store on a day-to-day basis.
These will vary based on the level of sales expected, and the location and size of your business.
But your e-commerce store's operating expenses should include the following items at a minimum:
- Staff Costs: This includes salaries, benefits, and payroll taxes for all employees working in your e-commerce store, including customer service representatives, warehouse workers, and marketing staff.
- Accountancy Fees: You will need to hire an accountant or use accounting software to manage your company's finances, track expenses, and prepare tax returns.
- Insurance Costs: As an e-commerce store, you will need to consider insurance for various risks, including product liability, cyber liability, and business interruption. This will help protect your business in case of any unforeseen events.
- Software Licences: Running an e-commerce store requires various software and tools, such as e-commerce platforms, marketing automation software, and accounting software. These usually come with recurring licensing fees.
- Banking Fees: You will need a business bank account to manage your finances, and this may include fees for transactions, wire transfers, and international payments.
- Web Hosting Fees: Your e-commerce store will need a website, and this will require web hosting services. This can range from basic shared hosting to more expensive dedicated hosting.
- Marketing Expenses: To attract customers and generate sales, you will need to invest in various marketing efforts, such as social media advertising, email marketing, and influencer partnerships.
- Shipping and Fulfillment Costs: As an e-commerce store, you will need to cover the costs of shipping and fulfilling orders, including packaging materials, shipping fees, and warehouse expenses.
- Inventory Costs: You will need to purchase or manufacture products to sell in your e-commerce store, which will incur inventory costs, such as purchasing materials, storage, and inventory management software.
- Customer Service Expenses: Providing excellent customer service is crucial for e-commerce success, and this may require investing in customer service software, hiring additional staff, or outsourcing to a call center.
- Website Maintenance and Updates: Your e-commerce website will require regular maintenance, updates, and improvements to ensure it runs smoothly and provides a positive user experience.
- Utilities: Running an e-commerce store will also incur various utility costs, such as electricity, internet, and phone services.
- Returns and Refunds: As with any business, your e-commerce store will experience returns and refunds, which will incur costs for processing, restocking, and shipping.
- Professional Services: You may need to hire outside professionals for specific tasks, such as lawyers for legal advice, consultants for marketing strategies, or designers for website updates.
- Taxes and Licenses: As a business, you will need to pay taxes and obtain necessary licenses and permits, which will incur costs.
This list is, of course, not exhaustive, and you'll have to adapt it according to your precise business model and size. A small e-commerce store might not have the same level of expenditure as a larger one, for example.
What investments are needed to start or grow an e-commerce store?
Once you have an idea of how much sales you could achieve and what it will cost to run your e-commerce store, it is time to look into the equipment required to launch or expand the activity.
For an e-commerce store, capital expenditures and initial working capital items could include:
- Website Design and Development: This includes the initial design and development of your e-commerce store's website, as well as any ongoing updates and improvements. This is an essential capital expenditure as your website is the foundation of your online business.
- Inventory and Equipment: As an e-commerce store, you will need to invest in inventory and equipment such as packaging materials, shipping supplies, and warehouse equipment. These are necessary for the day-to-day operations of your business and should be included in your expenditure forecast.
- Payment Processing Fees: You will need to factor in the cost of payment processing fees for online transactions. These fees can vary depending on the payment gateway you choose to use, so make sure to research and include them in your forecast.
- Fulfillment and Shipping Costs: If you plan on fulfilling and shipping orders yourself, you will need to budget for the costs of packaging materials, shipping labels, and postage. If you plan on using a fulfillment service, be sure to include their fees in your forecast.
- Website Hosting and Domain Name: Your e-commerce store's website will need to be hosted on a server and have a domain name registered. These are essential for your online presence and should be included in your expenditure forecast.
Again, this list will need to be adjusted according to the specificities of your e-commerce store.

The financing plan of your e-commerce store
The next step in the creation of your financial forecast for your e-commerce store 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 e-commerce store?
Now let's have a look at the main output tables of your e-commerce store's financial forecast.
The projected profit & loss statement
The projected profit & loss shows how profitable your e-commerce store is likely to be in the years to come.

For your e-commerce store 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 e-commerce stores, there is some leniency for startups which will have numbers that will look a bit different than existing businesses.
The projected balance sheet
Your e-commerce store'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 projected cash flow statement
A projected cash flow statement for an e-commerce store is used to show how much cash the business is generating or consuming.

The cash flow forecast is usually organised by nature to show three key metrics:
- The operating cash flow: do the core business activities generate or consume cash?
- The investing cash flow: how much is the business investing in long-term assets (this is usually compared to the level of fixed assets on the balance sheet to assess whether the business is regularly maintaining and renewing its equipment)?
- The financing cash flow: is the business raising new financing or repaying financiers (debt repayment, dividends)?
Cash is king and keeping an eye on future cash flows is imperative for running a successful business. Therefore, you should pay close attention to your e-commerce store's cash flow forecast.
If you are trying to secure financing, note that it is customary to provide both yearly and monthly cash flow forecasts in a financial plan - so that the reader can analyze seasonal variation and ensure the e-commerce store is appropriately capitalised.

Which tool should you use to create your e-commerce store's financial forecast?
Creating your e-commerce store'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 e-commerce store'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)

Calling in a financial consultant or chartered accountant
Enlisting the help of a consultant or accountant is also a good way to obtain a professional e-commerce store financial forecast.
The downside of this solution is its cost. From experience, obtaining a simple financial forecast over three years (including a balance sheet, income statement, and cash flow statement) is likely to cost a minimum of £700 or $1,000.
The indicative cost above, is for a small business, and a forecast is done as a one-shot exercise. Using a consultant or accountant to track your actuals vs. forecast and to keep your financial projections up to date on a monthly or quarterly basis will cost a lot more.
If you opt for this solution, make sure your accountant has in-depth knowledge of your industry, so that they may challenge your figures and offer insights (as opposed to just taking your assumptions at face value to create the forecast).
Why not use a spreadsheet such as Excel or Google Sheets to build your e-commerce store'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 e-commerce store 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 e-commerce store'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.
