I am Clean the invoice

Hello, jtmusa-trading.

I'll help you manage your invoices and payments in QuickBooks Online (QBO).

Beforehand, have you received a payment against the wrong invoice? If so, I'd be glad to help you fix this.

First, create a journal entry. Then, apply the payment to the correct invoice. Here's how:

1. Click +New and select Receive payment.
2. Choose the name of the customer.
3. From the Credits section, ensure the journal entry number and open balance amount are listed and checked.
4. Hit Save and Close.

If this isn't what you mean, would you mind sharing more details about your concern? This way, I can provide you with an accurate resolution.

Moreover, this article provides detailed information if you want to void or delete an invoice in QBO: Void or delete transactions in QuickBooks Online.

I appreciate any details you can provide. I’m looking forward to your reply. Have a great rest of the day.
