Troubleshooting Xero errors
Troubleshooting Xero errors
Occasionally, a sync between VanMan and Xero may fail. Here are the most common errors and how to resolve them.
Authentication expired
Error: "Xero authentication has expired. Please reconnect."
Your Xero connection token has expired. This can happen if the token has not been refreshed for an extended period.
Fix: Navigate to SettingsIntegrationsXero and click Reconnect. Authorise VanMan again through the Xero login screen.
Invalid account code
Error: "Account code '200' does not exist in Xero."
The account code assigned to an invoice line item does not match any code in your Xero chart of accounts.
Fix: Update the account code in VanMan to match a valid code from your Xero chart of accounts. You can set default codes in SettingsIntegrationsXero.
Check your default account codes after connecting Xero for the first time. Setting them correctly upfront prevents this error on every invoice.
Duplicate invoice
Error: "Invoice number already exists in Xero."
An invoice with the same number already exists in Xero, usually because it was manually created there.
Fix: Delete the duplicate invoice in Xero, or change the invoice number in VanMan before retrying the sync.
Contact mismatch
Error: "Contact email does not match an existing Xero contact."
VanMan creates contacts in Xero automatically when syncing invoices. This error occurs if the contact details conflict with an existing Xero contact.
Fix: Update the customer's email in VanMan to match the Xero contact, or merge the duplicate contacts in Xero.
Most sync errors resolve automatically on retry. VanMan retries failed syncs with exponential backoff. Check the audit log for details.
