Hey all! I just added this page to the Foundational Course that has a free spreadsheet to track your expenses and income along with a video walkthrough.
I'm working on a full course on how to set up Wave Accounting but if you need something simple and free the spreadsheet is something you can easily hand to your accountant at tax time.
PS - In general you should always know the ins and outs of where your money is going so you understand the health of your business!
