Confirm the order entered the workflow
Start by checking that the order exists in the selling channel and that the fulfillment workflow received the correct items, quantities and customer details.
Make routing rules explicit
Define which warehouse, 3PL or fulfillment service should handle each order so routing decisions are consistent and explainable.
Track shipment state separately from order state
An order can exist while fulfillment is delayed, partially shipped or missing tracking, so these states should not be treated as the same thing.
Keep tracking updates connected
When a shipment is created, the customer-facing channel should receive the correct carrier and tracking state through a supported workflow.
Turn exceptions into visible work
Unmatched SKUs, failed routing, missing tracking or delayed handoff should create an exception that can be reviewed instead of disappearing into background automation.
Verify completion on the selling channel
After fulfillment actions are taken, confirm that the channel customers use shows the expected shipment and tracking result.
