Business Planning

A guide to forecasting sales for the next quarter

Staff writer | 31 March 2026 | 6 months ago

As a business owner, you need to stay one step ahead of the market, and one step ahead of your competitors. This is why sales forecasting – which refers to the process of estimating your business’ revenue – is so important, especially focusing on the upcoming quarter.

However, don’t make the mistake of assuming that sales forecasting is all about numbers. That’s not the case. It’s about making better business decisions, using resources more effectively, and lowering risk.

Why is Sales Forecasting Important?

Cash Flow Confidence

Sales forecasting helps you to predict revenue and plan for upcoming expenses like business premises rent, staff wages and paying suppliers. For example, it might highlight that you can afford to increase your staffing during a busy season, or it might tell you to hold off for now. Without sales forecasting, you run the risk of spending too much and getting into cash flow problems.

Better Inventory Management

Having too much stock ties up money that could be used for other things, and having too little stock means you might miss out on sales. You can avoid making inventory mistakes by using seasonal trends and past data to make accurate predictions, making sure you always have just the right amount of stock.

Smart Use of Resources

Sales forecasting isn’t just about money, it’s about people, time and resource management. You can plan staffing levels, production schedules and marketing campaigns more effectively if you have a rough idea of when sales are likely to be higher.

Set Realistic Goals

With a sales forecast in hand, you can set achievable sales targets for your team. There’s no risk of you setting a target that’s completely out of reach, or setting a goal that’s too easy to achieve. This motivates employees and provides a benchmark for performance.

Gain Stakeholder Trust

Investors, lenders and business partners are more likely to trust and support businesses with a clear, data-driven plan, and a sales forecast is just that. It shows that you understand your business and your market, which can be key when it comes to securing funding or negotiating contracts.

How to Forecast Your Next Quarter’s Sales

When it comes to sales forecasting, there isn’t a one-size-fits-all approach. The most effective sales forecasting strategies tend to combine multiple methods, creating an accurate projection that works for your business.

Analyse Past Sales

There’s no way of being completely certain of what’s next for your business, and you can’t predict the future. But, you can use historical sales data to get a good idea of what’s to come. Look at seasonal trends, year-on-year growth patterns and repeat customer behaviour, all of which can help you to forecast what’s likely to happen in the next quarter.

Research the Market

Understanding the wider market is key, as things happening elsewhere can have an impact on your business. Economic indicators – like inflation, consumer confidence and interest rates – industry trends, competitor performance and changes to any legislation that’s related to your industry all play a part.

Look at Your Sales Pipeline

It’s a good idea to look at your current sales pipeline, and give probabilities to each potential deal to estimate the likely revenue it will generate. This helps you to avoid overestimating your upcoming income. Make sure to keep your pipeline up to date and review it regularly, as even small changes can significantly impact your sales forecast for the next quarter.

Consider Customer Feedback

When you have direct feedback from customers, you can make better sales predictions. Surveys that ask about seasonal preferences or plans to buy can give you a good idea of when demand is highest and lowest. For example, if you find out how many of your loyal customers are interested in an upcoming product line, you can guess how quickly products will sell out once they’re launched.

What Happens if You Don’t Accurately Forecast Sales

  • If you don’t forecast your sales for the next quarter, you might struggle to pay your employees and suppliers, because your cash flow doesn’t stretch quite as far as you need it to.
  • If you don’t plan for times when demand is high, you might not be ready to take on the increased workload, meaning missed sales opportunities are likely.
  • There’s a risk of you making the wrong business decisions if you don’t have a sales forecast to refer to. For example, you might hire someone, spend money on marketing or launch a product, when doing so is unlikely to pay off.
  • It’s hard to manage inventory without sales forecasting, as having too much stock ties up money you need elsewhere. On the other hand, having too little stock loses sales and negatively impacts customer trust.
  • It’s hard to run a business when you don’t know how much money you’ll make in the future. If you get into the habit of making predictions, you’ll have less stress and uncertainty to deal with.

Make the Most of Sales Forecasting

It’s not enough to quickly forecast your business’ sales for the next quarter, you need to make the most of the information it gives you. Don’t just make one forecast, review it often and update your predictions along the way. It’s also a good idea to use a mix of forecasting methods, as a combination of historical data, market research and sales pipeline analysis will give you the most accurate results. Use your forecast to plan for different situations and get ready for the unknown. Think about the best, worst and most likely outcomes, and put plans in place to handle whatever comes your way.
