Hi there RootCellar,
Thanks for bringing this up. I can help you resolve the deposit issue in QuickBooks.
Since the customer payments are already recorded in the system, you can exclude the transactions from the Banking section. Matching transactions from the Banking section to your existing QuickBooks transactions doesn't affect the bank balance.
It will only change the bank balance if you use the Add option instead of Match. To exclude transactions, you can follow the detailed steps outlined in the article below:
Exclude duplicates or personal expenses from downloaded bank transactions.
I'm here anytime you need help with the bank transactions in QuickBooks Online. Have a great day ahead.
