QuickBooks Online Error: Object Not Found : Something you're trying to use has been deleted. Check the fields with accounts, customers, items, vendors or employees.

Why the Sync Error occurs

This error occurs when something on a transaction has been deleted or the connection has been broken. The deletion may have occurred in Bill.com or in QuickBooks Online (QBO). This can be related to any item on the transaction such as accounts, items, classes, customers, vendors or the invoice/bill itself.

How to Fix the Sync Error

  1. In both Bill.com and in QBO, verify the chart of account(s), items, locations, classes, vendor and any employees on the bill have been deleted or determine if the invoice or bill was deleted
  2. Once the deleted entity is located, re-code it
  3. Sync again
