Thanks for posting to the Community, @TAILS222.
I'll be happy to share with you the steps on how to enter the credit to the debit card accurately. Then link it to the same job so that the materials cost on the job will be adjusted.
You can create a refund check so that you can link both transactions, the vendor refund, and materials cost adjustment of the job.
Here's how:
- Go to the Customers menu.
- Select Create Credit Memos/Refunds.
- Click the Refund icon from the top menu.
- Select the Items tab.
- Add the appropriate item from the Item column.
- Select a job from the Customer: Job column.
- Enter the needed details and click Save.
In case you need an additional reference in doing so, this article will be your source: Record a credit memo or refund in QuickBooks Desktop for Mac. It contains how to create and edit a credit memo.
