Financial Modelling Software vs Excel & Sheets

Financial modelling allows businesses to predict how the company is likely to perform in the future by building out different scenarios based on possible business decisions. While there are a number of ways that companies can run financial forecasts or scenarios, there is an ongoing debate among experts about which tools work better, Google Sheets or Excel versus financial forecasting software.

While Excel (or Google Sheets) is seen as a more traditional method for business forecasting, and the use of automated financial modelling tools as more modern, the decision on which to use for business projection purposes however, depends largely on the business’s overall future goals.

  • So, why should you care about choosing a financial forecasting tool as a startup?
  • Excel and Google Sheets are powerful tools, but human error remains their biggest limitation
  • Brixx helps businesses of all kinds and sizes rapidly model financial forecasting scenarios with ease

Excel and Google Sheets are powerful tools, but human error remains their biggest limitation

One of the main problems with using a Google Sheets or Excel spreadsheet for cash flow forecasting and scenario modelling, is that maintaining these can be time-consuming and labor intensive. While spreadsheets may work for businesses on a smaller scale, developing or developed businesses may require input from more than one person, increasing the amount of manpower required to complete a task that specialized forecasting software can do automatically.

While there is nothing wrong with choosing to use spreadsheets as a projection tool, they can be inherently inconsistent. This may be one of the reasons that larger companies find it difficult to amalgamate all of their data in an organized and cohesive way – leading them to explore automated cash flow modelling solutions.

Make no mistake however, Excel or Google Sheets can be a fantastic tool for businesses or startups that have the time to build out a custom template (whether from a standard downloadable version or from scratch) that will suit their specific needs. And for businesses with limited resources, nothing can beat their price!

Excel and Google Sheets are powerful tools, but human error remains their biggest limitation

Despite their popularity, a few other points to take into consideration when contemplating spreadsheet for forecasting are:

  • As the amount of data increases, spreadsheet become increasingly difficult to navigate – finding the data you’re looking for may take longer than you’d expect
  • The manual labor involved in compiling these spreadsheet use up valuable resources and open forecasts up to human error, wasting time and money
  • Spreadsheets do not have controls, rules and approvals that lead to a more streamlined process

Pros of using spreadsheets:

  • Free or near-free options available (Excel, Google Sheets)
  • Widely used
  • Easy to use, intuitive, no intensive training required
  • Formulas are provided and ready to use
  • Convenient way to organize data
  • Can be integrated with other software
  • Next-level calculations – using data entry and formulas
  • Avoid repetitive activity by automating calculations in a spreadsheet
  • Multiple user access for collaboration in Google Sheets
  • Multiple sheet tabs in one file make it easy to combine data
  • Universal file format

Cons of using spreadsheets:

  • Large amounts of data can be overwhelming to view and time-consuming to translate into reports
  • Human error and bias can lead to data issues
  • Lack of data history without proper backups
  • Lack of security, even if password protected
  • Difficult to identify syntax errors
  • Difficult to troubleshoot or test
  • Multiple versions of the same file being created when several people need to work on it
  • Not mobile friendly, especially when working with large amounts of data
  • Data entry is time consuming and can result in boredom, lower productivity, and inattentiveness that can ultimately lead to errors in the document
