Order flow
An order crosses the storefront, the ERP and fulfillment. It stays reliable when each handoff is defined, not just each system.
Decisions we work through
- Order identifiers that stay the same from checkout to shipment
- Mappings for customers, products, prices, taxes and shipping methods
- Duplicate prevention when a message is retried or sent twice
- Error handling that names who sees a failure and what they do next
- Fulfillment updates that return to the ERP and the customer
