Methods and tools for forecasting

FD Works is a supporting partner for the Tech South West StartUp Studio, a virtual accelerator for early stage tech companies in the South West.

The way to approach forecasting will depend on your situation. Starting from scratch with no previous data to draw on will look very different to a business that has been trading for a year or more. However, there are some similarities, and regardless of where you’re starting, you’ll want to consider the best way of going about it and what tools to use.

Bottom up forecasting

This method, otherwise known as quantitative forecasting, relies on previous data and financial statements. It’s best to take the lowest point and calculate from there, although you can take an average figure of typical months if that makes sense for your business. You’ll be able to see patterns from past data which makes the process simple, but don’t be lulled into just assuming that things will carry on as they are. It still takes critical thinking to understand the highs and lows of that data, why they happened, and get prepared to make the most of the good times and limit the bad.

Top down forecasting

Top down analysis starts with assessing your market as a whole. Once you’ve established the market size, you can make an estimate of how much of a share your business can take. By evaluating trends in the market you can be prepared to amplify your strengths and minimise your weaknesses.

When done with accuracy as a priority, over optimism, it can be effective, particularly for start ups or those introducing new products into the market. Given a choice, a combination of the two methods is ideal.

The right type of tool

Once you’ve settled on your method of forecasting, you can decide on which tool to use. SMEs differ to large businesses in the sense that they are complex and not easily represented in standard reports. Bearing this in mind there are a few key features that you should look for when deciding on what type of tool or software to use for your business.

Long term view

Your forecast should be able to reflect the time period that’s most relevant to your business. If you are scenario planning, then the immediate effects may seem positive, but could cost you down the line. You need to be able to see further than 12 months into the future, so your tool will ideally create a rolling forecast of up to five years.

Clear visibility

Forecasts can hold a lot of information. If you’re going to engage with yours on a regular basis then it needs to work for you. Your forecasting tool should give you a clear and simple view of your cash flow report, balance sheet, and any other statement relevant to your business.

Customise, don’t over complicate

Taking a complex system like an SME and trying to reflect that on a spreadsheet isn’t as simple as it seems. If it doesn’t work for you, then you won’t use it. Having a bespoke tool should mean that you recognise your day to day in your forecast. Make it work for you, not the other way around.

Forecasting isn’t easy for SME owners. While we know what it takes to create a successful business, we spoke to other SME founders about their experiences with forecasting too. Understanding what barriers they faced in creating and maintaining a useful forecast helped us create a tool which actually serves complex SMEs instead of hindering them.
