Why is Xero accounting not working or showing errors? +
Xero errors in 2026: (1) Connection to bank feed broken — Xero bank feeds require periodic re-authentication with your bank. Go to Accounting → Bank Accounts → Manage Account → Refresh. (2) Sync stopped with accounting software — if using a connector (A2X, Dext, Hubdoc), the OAuth token may have expired; reconnect in the connector's settings. (3) Invoices not sending — Xero email delivery can fail if your custom email domain isn't verified. Check Settings → Email Settings. (4) API integration returning 403 — your Xero app may not have the right scopes for the operation you're attempting.
How do I troubleshoot Xero accounting step by step? +
Xero diagnostic flow: (1) Check Xero's status at status.xero.com — some issues are platform-wide. (2) In Xero, go to Settings → Connections to see all connected apps and their status. (3) For bank reconciliation issues: check the bank feed's last sync date and transaction count. (4) For invoice errors: go to Business → Invoices and check the 'Send Later' queue for stuck emails. (5) For API issues: use the Xero API Explorer at developer.xero.com to test calls directly — this isolates whether the issue is in your code or Xero's API.
How do I connect Xero to my payment processor? +
Xero payment integrations: (1) Stripe + Xero — use the official Xero Stripe integration or GoCardless for direct debit. Both sync payments automatically to Xero invoices. (2) Square + Xero — use the official Square + Xero integration from Xero's app marketplace. (3) PayPal + Xero — native PayPal integration in Xero's app marketplace. (4) For custom payment flows, use Xero's Payments API to mark invoices as paid when your processor receives payment. (5) Make.com and Zapier both have Xero connectors for non-native integrations.
What are the common Xero API errors and how do I fix them? +
Xero API errors: 401 — access token expired (Xero tokens expire every 30 minutes; implement token refresh). 403 — insufficient scopes on your OAuth app; check the required scopes for the endpoint. 404 — resource not found (organization, invoice, or contact ID doesn't match). 422 — validation error (check the response body for the specific field causing the error). 429 — rate limit (Xero allows 60 calls/minute; add delays). For Xero API debugging, always log the full response body, not just the status code.
