Let me help you correct the invoice that was marked as paid, Edseymour.
We'll have to clear the payment to unlink the transaction and change the invoice status. You can follow these steps:
- Open the invoice.
- Under the PAYMENT STATUS, click the payment link.
- Click the date link.
- Select Clear Payment.
- Click Save and close.
- Select Yes to confirm.
The invoice will now go back to unpaid status.
I'll add this reference to help with receiving the payments: Record invoice payments in QuickBooks Online.
