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 can't sync to Xero because there's 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 isn't syncing in from Xero, don't create the contact manually in Bill.com. 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 the contact to a group doesn't resolve the issue or a merging of duplicates is required
