How to Prevent an Automation From Sending a Duplicate Invoice Notice

A workflow may send an invoice notice twice after a retry, a status update, or a manual resend. Customers may pay twice or contact support because the messages look like separate invoices.

What to check

Compare invoice IDs, send logs, event IDs, retries, provider delivery receipts, and whether each trigger creates a new message record. Check concurrent workflow executions.

Recommended next step

Make notifications idempotent per invoice and event, distinguish resend actions from new invoices, and test retries and duplicate events before release.
