Xero Sync Error: The contact name is already assigned to another contact. The contact name must be unique across all active contacts

Why the Sync Error occurs

This error occurs when a customer or vendor cannot sync to because there is a contact with the same name in Xero (either active or inactive).

How to Fix the Sync Error

  • Ensure all Vendors and Customers have unique names when syncing to Xero
  • If a contact is not syncing in from Xero, do not create the contact manually. In Xero, ensure the contact has been assigned to either the Sync to Bill.com Vendors or Sync to Bill.com Customers group.
  • Contact Customer Support if assigning contact to a group does not resolve the issue or a merging of duplicates is required
