Double-entry accounting. The standard method for tracking where your money comes from
and where it goes. Following the old saw that money doesn’t grow on trees,

money on your invoice comes in as income and goes into your Accounts Receivable
account. Then, when you deposit the payment, the money comes out of the
Accounts Receivable account and goes into your checking account.
