QuickBooks Online Sync Error: The vendor on one of bills paid in this transaction does not match the vendor on that bill in QBO. This could happen because of an incorrect vendor merge in QBO

Why the Sync Error occurs

This error occurs when a vendor is different on the payment in PayMaker from what is on the bill in QuickBooks Online. This can happen if:

  • The bill was updated in QuickBooks Online to a different vendor
  • There was a vendor merge in QuickBooks Online, but in PayMaker
  • A vendor was made inactive in PayMaker

How to Fix the Sync Error

There are three (3) options to resolve this issue:

  • If the previous vendor is still active in QuickBooks Online, update the bill to the original vendor
  • Select to Not Sync the payment and manually mark the bill as paid in QuickBooks Online
  • If there was a merge and the payment should sync, contact Customer Support to request to merge the vendor
