I have a customer that paid an invoice and check was returned-no signature. I already reconciled that month but customer has sent a replacement check and I need to post

Hello there, user52402. I'm here to assist you in recording the replacement check so that your report reflects accurate data.

You can consider creating a Journal Entry (JE) affecting the Accounts Receivable (A/R). Then, unlink the customer payment from the original invoice and link it with the JE. However, I suggest consulting your accountant for advice on how to properly handle this matter so your report will reflect accurate data.

Once done, receive the customer payment of the original invoice with the replacement check. I can guide you to accomplish this in QBO.

Here's how to record the returned check in a Journal Entry:

1. Go to + New, and under Other, select Journal Entry.
2. Enter the date the check bounced in the Journal date field.
3. On the first line, select Accounts Receivable from the Account menu.
4. In the Debits column, enter the amount of the bounced check.
5. Select the customer from the menu in the Name column.
6. On the second line, select the bank account from the Account menu.
7. The amount should appear automatically in the Credits field.
8. Enter a notation explaining the reason for the journal entry in the Memo field.
9. Select Save.

Next, clear the original invoice, paid with the bounced check, and link the returned check to the Journal Entry:

1. Find the received payment transaction. To help in this task, you can consider using the Magnifying glass to find the customer payment by entering the amount, date, or transaction number.
2. In the Receive payment window, uncheck the invoice where the payment is linked.
3. Place a checkmark for the JE created.
4. Review other details. Then, hit Save and close.

Once done, receive the replacement check payment of the original invoice. Here's how:

1. Select + New.
2. Under Customers, choose Receive Payment.
3. Select the customer from the Customer dropdown list.
4. Enter the Payment date and Payment method for the new payment.
5. Select the Deposit to account from the dropdown list.
6. Enter the Amount received.
7. Select the invoice you created from the Outstanding Transactions list.
8. Select Save and Close.

After that, you'll need to manually reconcile the added transactions so your report will be accurate. Click the letter "C" and change it to "R".
