Once your integration is active, Katana imports new merchant-fulfilled (FBM) orders automatically - immediately when Amazon sends the order notification
Unlike FBA orders, which arrive in Katana already Delivered, FBM orders arrive open - fulfilling them is your job, and Katana reports your progress back to Amazon.
What happens when an order imports
If a new FBM order is detected by Katana, the following steps happen automatically:
Fetches order data from Amazon - the full Amazon order ID , line items with quantities and prices, tax data (depending on the marketplace and whether tax data is available), the shipping service level, and Amazon's promised delivery date.
Matches products by checking each SKU against your Katana variants.
If SKU aliasing is used: each product is matched based on the FBM alias mapping
If SKU aliasing is not used: the Amazon seller SKU is matched directly against the Katana variant code
Creates a sales order (SO) in your FBM fulfillment location, with the delivery deadline set to Amazon's promised delivery date.
The order appears in the Sell screen's Open tab tagged "Amazon FBM", so it's easy to tell your Amazon workload apart from other channels. You can also filter sales reports by the Amazon FBM channel.
Note: Buyer contact details don't appear on Katana orders. Create your shipping label in Amazon Seller Central (one click from the order) or in your carrier tools - the buyer's address is available there.
Fulfilling an FBM order
Pick and pack the order using your normal Katana workflow - from the Sell screen or in the Warehouse App.
Create the shipping label in your usual shipping flow - for example, directly from the order in Amazon Seller Central.
Add tracking details to the sales order: the carrier, the shipping method (service level), the tracking number, and optionally a tracking URL.
A carrier is required together with the tracking number - Amazon's Valid Tracking Rate policy expects both, so Katana won't let you mark the order Delivered with a tracking number but no carrier
If your carrier isn't in Amazon's standard list (e.g. UPS, USPS, FedEx, DHL, and others), Katana sends it as "Other" along with the carrier name you entered
Mark the order as Delivered once it ships. Shipping only part of the order? Mark it Partially Delivered - Amazon receives a partial shipment confirmation with the shipped quantities.
What Katana writes back to Amazon
When you mark an FBM order Delivered, Katana confirms the shipment to Amazon, including the carrier, service level, and tracking number. Amazon marks the order as shipped, and the buyer sees the tracking details on their order page.
Because a missed confirmation directly hurts your Amazon seller metrics (Late Shipment Rate, Order Defect Rate, Valid Tracking Rate), Katana treats this write-back carefully:
Verified - Katana confirms the update actually reached Amazon before considering the job done
Retried automatically - temporary failures (network issues, Amazon rate limits) are retried without you needing to act
Updated the tracking number after shipping? Katana sends the updated details to Amazon as well.
Note: The write-back is one-way. Reverting an order from Delivered in Katana doesn't un-ship it on Amazon - manage such cases in Seller Central.
Notes and limitations
Orders are imported from all the marketplaces of your Amazon Seller account into the FBM fulfillment location you selected during setup
Duplicate protection: each order is identified by its Amazon order ID, so an order is never imported twice
Returns and refunds are handled in Amazon Seller Central
If a buyer cancels an order on Amazon before you ship, cancel it in Seller Central and update the corresponding Katana sales order
