Is Excel good for invoicing?

You can use Excel for invoicing. But there are better invoicing software platforms available - like ConvertCalculator.

You must be skilled in using Excel to get the best out of it for invoicing. If you’re not, you need to learn how to use it properly. And the learning curve can be high when figuring out Excel.

Here are other reasons Excel isn’t the best for invoicing:

  • Can’t process payments directly from the invoice
  • Manually entering data is prone to errors
  • Spreadsheets can get unruly
  • Less flexible for changes
  • Clunky on mobile

With ConvertCalculator, you can set your invoicing on autopilot. It makes the entire process much more convenient.

Does Google do invoicing?

Google doesn’t do invoicing directly. You can create an invoice template with Google Docs. It’s easy to do, but you won’t be able to:

  • Accept online payments
  • Automate workflows
  • Track expenses
  • Create reports

Google also lets you install third-party invoicing software from Google Workspace Marketplace.
