How do I deal with a client who has a bounced direct debit to a supplier

Hello Fionaiow, 

Welcome to the Community page, 

Here are the steps you need to do to record this in your Quickbooks, 

1. undo the payment form the bill if this has been matched

2.once the payment of the bill has been deleted. it should go back into the for review section on the banking page

3. on the banking screen, add the payment in again as an expense to creditors and no vat, be sure to put the supplier name in

4.then when the money bounces back, 

5. on the banking screen, record the money coming in as deposit to creditors, supplier name, no vat

6.once this has been done, click new transaction in the top right-hand corner of the supplier screen

7. put in the supplier name 

8.match the expense and the deposit off, save and close 

That is how to bounce a payment correctly.
