Depositing cash

Hello! Gosh, that doesn't make any difference. You should read this article in the learning center: A professional purchase paid for with your private bank account?

You should apply the same reasoning for your purchases to your income. How something has it been paid for is completely irrelevant. Cash, bank transfer, etc. plays no role whatsoever. Since you didn't create a sales invoice to those people, you can use daily receipts.

That's right, what the money does doesn't matter much in a sole proprietorship. Just put those documents (income, expenses) in your accounts and that's it. Cash or whatever, it doesn't matter.
