Thanks for following up here, heatingguys.

In addition to what my colleague KhimG recommended, there's another option to consider to apply a vendor credit to a project or customer without a bill. I'm listing the details below.

This can be done using steps similar to those listed above, but by creating a Check, rather than a Vendor Credit. With a check, paying money to a payee will be shown, and the money will instantly leave your account (instead of showing as a credit on the vendor's profile).

1. Click the + New button and choose Check.

2. Select a vendor from the drop-down menu.

3. Enter the Category.

4. Choose the correct Customer/Project.

5. Click Save and close.

Let me know how this works for you. I'm only a comment away if you have any other questions.
