Hello, flynlowjoe.
You don't need to call in. I'd be more than happy to show you the steps on how to post a credit to a vendor. I'll also throw in a bunch of screenshots to help you out (click the images to enlarge them).
You'll want to simply record a vendor credit for the total amount of the check received. Here's how:
- Click the + New icon, then choose Vendor credit.
- Enter the details of the credit such.
- Type the amount under AMOUNT.
- Add other details such as references, description, check number, etc.
- Once done, click Save and close.


At this point, there are two ways to handle this. We can leave the vendor credit as it is for future bills, or deposit the amount to your bank account.
Leave the credit as it is and use it for future bills:
- Create a bill for the vendor if you haven't already.
- Save the bill and open it again.
- Click the Mark as paid button.
- You'll be redirected to the Bill payment screen, and the vendor credit will appear.
- Ensure to check the bill and the vendor credit transactions.
- Add details such as memo, reference numbers, etc..
- Once done, click Save and close.

This will close out the vendor credit and mark the recent bill as paid.
Deposit the vendor credit to your bank account:
- Click the + New icon, then choose Bank deposit.
- Choose the bank where you want to deposit the amount under Account.
- Select the vendor's profile under RECEIVED FROM.
- Choose Accounts Payable under ACCOUNT.
- Enter the amount.
- Add other information such as reference numbers, memo, etc..
- Once done, click Save and close.

This will zero out the negative balance in the vendor's profile and will deposit the amount to your bank. To close out the vendor credit:
- Click the + New button again, then select Pay bills.
- Choose the bank account where the amount was deposited to.
- Check the vendor, and leave the transaction as is.
- Once done, click Save.

After doing the process, your Accounts Payable will be debited for the amount and your bank will be credited.
