How do you deposit Non Customer Related Income correctly

Add the check as a line item to a deposit.

I did that and it's not matching the bank balance - the amount is exactly the same amount as the Non Customer deposit. I posted it as Other Income.

Hello there, @Catz. 

Welcome to the Community, I'd be happy to answer your questions today. 

If your bank register balance in QuickBooks Desktop doesn’t match your actual bank balance, make sure to post it to the right bank account to match your bank balance. 

For the posting accounts, I recommend contacting your accountant for guidance in handling these receipts. They can share the best accounting practices to follow concerning the choice of accounts you intend to use.

If you haven't yet, here's an article you can use to find someone near you with whom you can work on your accounting books: QuickBooks Certified ProAdvisor. 

For now, I'm giving you a lead so you can generate a report showing other data of transactions based on the financial status you need. To do that, here's the topic you can utilize for reference: Create and Manage Reports in QuickBooks Desktop.

Don't hesitate to leave a comment below if you're referring to something else or if you have any other questions about bank transactions. Have a good day!

A deposit is a deposit. It doesn't matter what its contents are, whether from a customer Payment or just entered in the detail area of the deposit, or just entered in your bank account register. They all work the same way.

Also, individual transactions don't "match" your bank balance. I'm not sure what you mean by that, but if you mean that you recorded an individual deposit for the money but that's not what you did when you actually made the deposit, then change the what you did in QuickBooks until it matches what you actually did in the real world.

We only have one bank account - but I did make sure of the correct bank.

I have always been able to figure out why the QBD balance doesn't match the spreadsheet I have created - this doesn't make any sense since I've posted the deposit into QBD and it was deposited into the bank
