Hi, Ruben. In QuickBooks, if you record an invoice payment as cash and then later deposit that cash into your connected bank account, the income should be handled correctly and not listed twice.
The system tracks the payment when it is recorded, and the bank deposit reflects the movement of funds, not additional income. Just ensure you categorize the deposit as a transfer or deposit of existing income, not as new income, to avoid duplication.
If you have any further questions, please don't hesitate to reply. We’re here to help.
