Xero sync error: Another invoice with this invoice number already exists in Xero

Why the sync error occurs

This error occurs when an invoice can't sync to Xero because the invoice number already exists in Xero.

How to fix the sync error

  • If this is a new invoice, edit the invoice number to one that doesn't already exist in Xero and sync again
  • If the invoice was also manually created in Xero, contact Customer Support to link the invoices
    • In order for the sync to work properly, bills should be created in either Xero or Cashflow360 and synced to the other system
