Why Does CS-Cart Send Two Order Notifications for One Purchase?

Duplicate notifications can be caused by overlapping status triggers, payment callback retries, add-on behavior, or a customer refreshing a completion page. Customers may believe they placed multiple orders even when only one exists.

What to check

Compare order IDs, notification logs, payment events, status transitions, add-ons, and email queue history. Determine whether there are duplicate orders or only duplicate messages, and reproduce using a test payment flow.

Recommended next step

Make notification triggers idempotent and ensure each intended state transition sends only the relevant message. Confirm payment callbacks are safe to retry and explain the order status clearly to customers.
