Why Does CS-Cart Send an Order Confirmation Before Inventory Is Reserved?

An order email may be sent before stock is reserved or checked, so a later inventory failure can invalidate the customer’s confirmation. This is especially likely with concurrent purchases or delayed fulfillment integration.

What to check

Review order creation, inventory reservation timing, stock validation, payment capture sequence, notification triggers, and integration retries. Test two concurrent orders for the final unit in a safe environment.

Recommended next step

Coordinate reservation and confirmation rules so messages reflect actual order acceptance. Reconcile payment and stock states and use accurate wording for pending orders.
