A few possible causes of this error message could be:

  • 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.
  • If you are tracking firm users on bills (see here), a Class or Subclass related to a User in Clio may have been deleted


Change the name of the remaining QBO Contact to something unique, clicking Retry on the QBO error for the Contact itself, and then in QBO merging the previously existing contact into the newly created one. For details on how to merge a Contact within QBO, please see here.

Change the name of the Contact in Clio. This will create a new contact in QBO which you can then merge the old contact in QBO to. For details on how to merge a Contact within QBO, please see here.
