QuickBooks Online Sync Error: Business Validation Errors: This vendor cannot be deleted because it is used on a recurring template or scheduled liability payment in QBO

Why the Sync Error occurs

This error occurs when a deleted vendor, customer, or account in PayMaker is trying to sync to QuickBooks Online (QBO), but it has one or more recurring bills/invoice, or has one or more currently scheduled payments in QBO.

How to Fix the Sync Error

Delete the recurring bill setup in QBO, or void the scheduled payment in QBO, and sync again.

If you do not want to delete the recurring bill or void the payment, you can restore the deleted item in PayMaker, and delete when there are no longer related payments or recurring bills.
