In this video I give an overview of using Wave Accounting to track income and expenses for your side hustle. This software also allows you to send professional estimates and invoices to customers. Having your data organized and summarized can make things a lot easier for tax time.
This software used to be free but now you have to pay a monthly subscription to use some features such as connecting a bank account to auto-import transactions
