Receive payment for vendor credit - Quickbooks online

We can use the Vendor Credit feature, yfr.

This is used to record credits that we can apply on your vendor's bills. I can show you how to do it:

1. Go to the Plus icon and select Vendor Credit.
2. Select the Vendor and enter all the details needed.
3. Click Save and close.

Then, these are the steps to follow when it's time to apply it to a bill:

1. From the Plus icon, select Pay Bills.
2. Select a bill from the list. Check the credits to apply under the Credit Applied column. 
3. Make sure all information are correct. Hit Save and close.

I'd be glad to help you if you have other concerns. Have a great day!
