- Quickbooks Error Code (2500): Invalid Reference Id. Something you're trying to use has been deleted. Check the fields with accounts, customers, items, vendors or employees.
- Clio Web App
- Bill Syncing
- Quickbooks Online
-The item referenced was deleted in QBO or Clio.
-The Contact may have originally been duplicated in Clio. Then the incorrect Contact was deleted in QuickBooks Online, leaving no Contact for Clio to sync future updates/items, which would produce this 2500 error.
By changing the name of the remaining QBO Contact to something unique, clicking Re-sync on the QBO error for the Contact itself, and then in QBO merging the previously existing contact into the newly created one.
