Thanks for joining the thread, @CindyC885. Let me provide you with ways to handle your concerns.

To begin, let's create a vendor credit issued by the vendor to your business. Then, create a credit memo for the customer.

Here's how to create a credit memo for the credit:

1. Go to + New and choose Credit memo.
2. From the Customer dropdown, select the customer's name.
3. Enter the credit memo details, such as the date and the amount.
4. Fill in the necessary details.
5. Once done, click Save and close.

Then, pay the bills to mark them as paid and add a billable expense to include to the customer's invoice.

Additionally, you can run a report to get an overview of your business.

Please let me know if you require further assistance in managing your customer. I'll be here to help you in any way I can.
