7 Reasons Not To Use Spreadsheets To Manage Revenue Forecasts & What To Do Instead

For most companies, nothing starts until the revenue forecast plan is set. Having an accurate revenue forecast allows the company to set budgets across the organization, expectations for hiring, and even purchase order sizes for raw materials.

With revenue forecasting being so vital to a company’s success, it needs to be accurate. For the following reasons, we Do Not recommend using spreadsheets like Excel to do your revenue forecasting. Do not worry, we also provide a better solution that will make your revenue forecasting easier and more accurate.

7 Big Problems With Spreadsheets

It’s a Manual Process

Sales revenue is usually tracked and updated in a sales customer relationship management (CRM) system like Salesforce. So for an FP&A analyst or Sales Finance manager to forecast revenue, they have to manually export this information out of Salesforce and into a spreadsheet. This is just the start when updating, syncing, and organizing the data from the last time the report was run.

Need to Modify the Data

Once the sales information is exported the finance team gets involved and still has to modify the data to improve the reports to be more accurate. Not all sales in the pipeline will close, and oftentimes, not all of the “closed” deals will end up working out.

A $50,000 closed sales deal can mean a lot of different things to the finance team. Some common questions that financial planning analysts have to ask themselves to figure out how to best contribute the potential revenue are:

  • Is it a one-time sale vs. monthly recurring revenue?
  • What is the revenue schedule for this deal?
  • Is there an expected revenue ramp before the deal reaches maturity?
  • What is the weighting of the revenue with phases or confidence of closing?

Quickly Out of Date

After the sales data is manually downloaded out of the CRM it is frozen in time. Meaning every hour the sales team is making more sales and changing deals, they are not being accounted for by Finance in their revenue forecast. Depending on the size of the sales team and the number of deals, revenue forecasts, and how long it takes to recast revenue plans from the pipeline, it can become inaccurate very quickly.

For some companies by the time they download and prepare revenue forecasts from the pipeline data for their revenue forecast the information is no longer relevant because so much has changed.

Common Spreadsheet Errors

We are all human so mistakes happen. We don’t want those mistakes to happen on something as important as forecasting the revenue of the company.

It can happen to anyone, for example in 2012 JP Morgan was hit with a $6 billion trading loss due to Excel copy-and-paste error. You can check out six more examples of how spreadsheet errors have cost companies millions of dollars.

In addition rules applied to forecast revenue in spreadsheets may be inconsistent from period to period.

Removing the human element from collecting and modifying your data will reduce the chance of someone accidentally fat fingering or messing up a formula.

Hard to Work as a Team

Excel and most spreadsheet tools are a single-user tool. This makes it difficult for teams to work on the same spreadsheet. Also, there may be certain assumptions, rules, or calculations that you don’t want everyone on the team to know about or have access to.

Confusion With Multiple Versions

When working with team members, often each member will make a copy of the spreadsheet to do their own calculations. Trying to put all of these pieces and versions back together again without making any mistakes can be tedious and painful.

Too Large To Share

Once you have finished your report how are you going to share it with the C-Suite? Most likely it will be through email which can cause a lot of problems for businesses.

First, with confidential company information, you want to be careful to not accidentally send the email to an unintentional employee or worse somebody outside the company.

Second, some of these reports can get to be large in size and easily exceed the common 25MB size limit for most emails to be sent.
