Hello there, @andie787.
I appreciate you joining this thread. Allow me to step in and share some insights about managing vendor transactions in QuickBooks Online.
In order to record the supplier credit in your bank account, you will have to enter it as a deposit transaction and post to the A/P account.
After entering it, you can match the deposit right away with your bank transaction, andie787.
I'm still here to help you more if you have additional questions. Just add a comment or mention my name. Have a good one!
