Why the Sync Error occurs
This error occurs when a vendor credit is applied to a bill in Bill.com and that application is trying to sync to QuickBooks Online, but the open balance of the bill in QuickBooks Online is less than the credit amount applied.
How to Fix the Sync Error
If the bill is already marked as paid in QuickBooks Online, you should research the credit and payment appliications in both QuickBooks Online and Bill.com, and be sure they are both correct and match.
- If the credits on the bill in Bill.com are correct, void the payment and/or remove the credits in QuickBooks Online, and let the credit application sync over from Bill.com
- If the credits on the bill in QuickBooks Online are correct, remove the credits in Bill.com
- If both QuickBooks Online and Bill.com are correct, contact Customer Support to clear the error
