Invalid Reference Id : Something you're trying to use has been made inactive. Check the fields with accounts, customers, items, vendors or employees.
This error occurs when the account, customer, item, vendor, and/or class on a bill, or the bill itself that is trying to sync has been deleted in QuickBooks Online (QBO), and sync cannot update or create the bill.
- In QBO, check to see if the vendor and any accounts, customers, items, or classes listed in the bill have been deleted.
- Also check to see if the bill itself was deleted in QBO
- Once you have found what has been deleted, reactivate it, and then sync again.
- If you are unable to reactivate the item that was deleted, or if you see that nothing has been deleted, contact Customer Support.
