Every variant resolves
Test the deepest configurable product you sell, not a simple one. Mapping drift starts with variants nobody checked.

The platform you chose for control creates the complexity fulfillment has to absorb.
Brands land on Adobe Commerce or Magento Open Source because a hosted cart stopped fitting: configurable products with deep option trees, customer-group pricing, bespoke order logic, multiple storefronts on one backend. Every one of those decisions arrives at the warehouse as something to resolve before a picker can move.
Each variant has to resolve to a distinct item on the shelf, which is what SKU matching does during setup. On a Magento build this is the highest-risk part of the integration, because a parent product with many variants is many physical items, and a mapping that is right for the parent can still be wrong for a variant. Test your deepest configurable product rather than a simple one.
They should, but verify rather than assume. If your build carries gift messaging, delivery windows or B2B purchase order references on the order, place a test order that includes them and confirm they arrive. Magento supports REST, GraphQL and SOAP, so where something does not map, a connection can usually be built to carry it.
Platform APIs change, credentials expire, and SKU mappings drift when products are renamed or variants are added. Ask any provider directly how they stay ahead of platform API updates and what their maintenance commitment is. When a sync does break, report it with the exact time orders stopped appearing and a sample order number so the investigation starts from facts.
On a customised build, these are the four that break silently.
Test the deepest configurable product you sell, not a simple one. Mapping drift starts with variants nobody checked.
Place a test order carrying whatever your build adds to an order and confirm it reaches the warehouse.
Decide whether a partially available order waits or ships in parts, and make the customer message match.
Credentials expire and endpoints move. Know whose job it is before it happens, not after orders stop appearing.
