Revenue forecasting is one of the most critical elements of a business plan. Accurate forecasting can help you validate the business case for your new product or service and help you build trust among future investors and partners.

Poor forecasting, on the other hand, can sabotage your business before it even gets off the ground. And yet, many startups don’t give their forecast the attention it deserves. They end up getting the numbers wrong … by a long shot.

If a startup goes under, it’s most often within the first two years and is usually a direct result of poor financial management and the business running out of capital.

Revenue forecasts are one of the most overlooked areas of the business plan, yet an accurate and realistic forecast is vital to the health and longevity of a business.

A Quick Review—What is Forecasting?

The concept of revenue forecasting is pretty straightforward. Simply put, it’s the calculation of the amount of money a company will receive from sales during a particular period. Most companies determine forecasts for a period of time in the future based on actual sales revenue earned in the past. For a startup, this presents an obvious problem with key variables of the forecasting equation being unknown. 

Forecasting Can Feel Like Throwing a Dart Blindfolded. Why is it Such a Critical Step in the Business Planning Process?

When starting out, your reputation is what you’re selling. If you’re trying secure funding or recruit the right team, you need to sell them on your vision and dream. Backing that up with realistic revenue expectations based on researched data is one way of the most important ways to show your key stakeholders that you’ve developed a firm business case for a product or service that can be profitable.

As the owner of the business about to make a large investment of time and money into your new venture, solid, accurate projections are the clearest way to also prove to yourself that your investment will be a profitable one.

Informed projections based on in-depth research, quality data and an understanding of your target market back-up your belief in your product or service and show you’ve done your homework to validate your idea as one that’s worth pursuing.

The Three Common Forecasting Traps Entrepreneurs Fall Into

Giving the revenue forecast its deserved place in a business plan isn’t an easy task. So, why is it that forecasts are a challenge for startups?

  1. The Lack-of-Data Trap. It’s difficult, if not impossible, to forecast accurately when starting your business. For all other businesses with historical data, past metrics are used to project profits and losses. This data is simply not available when you’re starting out.
  2. The Over-Simplification Trap. Confident entrepreneurs typically project growth linearly with consistent growth over time. This creates what looks like a ‘hockey stick’ graph – a forecast that the startup will have stellar growth that keeps going up and up indefinitely. Investors will immediately meet hockey stick graphs with skepticism, knowing the projection is oversimplified.
  3. The Not-Based-in-Reality Trap. Similar to assuming immediate and consistent growth right out of the gate, entrepreneurs tend to cherry-pick data and leave out other critical pieces of the puzzle. Demand for your product, competition, market size, pricing, and marketing expenses are just a handful of the elements of a well-developed forecast that a surprising number of owners omit.

How to Avoid the Pitfalls and Create a Solid Startup Revenue Forecast

The first step in the process is learning how to avoid what’s referred to as “confirmation bias.” We usually test to prove that our hunches are correct, which is where things can go wrong in the revenue forecast. It’s your job as an entrepreneur to be aware of this pitfall and find ways to reduce or eliminate confirmation bias.

Once you’ve addressed and mitigated your confirmation bias, there are two primary areas of the plan that you need to lock down before you can accurately project revenue for your first twelve months.

1. Understanding Market Demand

Market demand for a product is the anticipated total volume purchased by a defined customer group in a defined geographical area during a defined period of time in a defined environment. Once you understand market demand, you can estimate your company’s potential share of that market.

Also, consider how you’ll gain market share. Will you steal it from your competitors? Or, will your product or service open up opportunities to create new market share? You’ll want to estimate future market demand for your products or services based on the growth of sales in the industry and changes in market share. A place to begin when accessing market demand for your product or service over a competitor could include asking yourself questions like:

  • What is the market’s capacity for my product or service?
  • Who may enter the market after me?
  • What makes my business valuable and can I clearly communicate the value to customers?

2. Sales Forecasting

Here’s where things get a bit more challenging. Accurately predicting future sales is perhaps the most difficult part of the revenue forecasting process. You’ll need to factor in what your management team expects and pair that with the estimated demand for your products or services at your proposed price points.

Think ahead to all of the potential company or market shifts and how those changes may impact sales, such as:

  • Price changes or promotions
  • Seasonal or cyclical factors including economic activity
  • Marketing and branding changes
  • Erratic events like strikes, fads, or disturbances to the market

Consider quantifying your sales forecasts in terms of ranges rather than absolutes. This communicates to a potential lender, VC firm and your partners and staff that you’re the type of owner who’s realistic and operating under a biased methodology. It also gives you the freedom to evaluate and adjust your sales and overall revenue projections after your business gets started and build even greater trust with key players along the way.

You’ve Done Your Research. Now What?
