This situation occurs when there's unapplied payments or vendor credits that aren't linked to any expense transactions. I'd suggest going through your supplier's list and locate those with account balance differences.
Click the Expenses tab.
Click the Suppliers sub tab.
Select a supplier that has a different on their account balance.
Look for any unapplied payments or vendor credits that are still showing open. Link them to the correct transactions.
You can also open your Accounts payable aging detail report. This lists all your payables, including vendor credits.
Click the Reports tab.
You can either search for Accounts payable aging detailvia the search box. You can also scroll down and look for the What you owe section, then select Accounts payable aging detail.
