Why is my income as counted when I create an invoice and when the customer pays it online? This is duplicating my revenue.

Thanks for posting here, @accounting608. Let us share insights on why you may have noticed a duplication in your revenue after the invoice online payment in QuickBooks Online (QBO).

It's essential to note that when a customer pays online, the payment is recorded automatically in the bank. Therefore, there is no need to receive the payment manually. Manually recording an online payment may result in duplicating the income.

To void the duplicate income, you can delete it from the Chart of accounts. Let me show you how:

1. In your QuickBooks, go to Transactions.
2. Select Chart of accounts. 
3. To proceed, choose the account that received the payment.
4. Go to View register, then click the duplicate payment.
5. Once done, hit Delete.
