Katana's integration with Amazon FBM (Fulfilled by Merchant) is built for sellers who ship Amazon orders from their own warehouse. FBM orders flow into Katana automatically, you fulfill them with your normal Katana workflow, and Katana keeps Amazon stock levels accurate and writes tracking and delivery status back to Amazon.
The FBM integration runs alongside the Amazon FBA integration as a separate connection - you can run FBA, FBM, or both side by side on the same Amazon account. It works across all the marketplaces of your Amazon Seller account.
Key features
Flow | Direction | What syncs |
Mapping | Amazon → Katana | FBM listings linked to Katana items by SKU or FBM SKU alias |
Inventory push | Katana → Amazon | In stock (or In stock + Expected) in real time; kits and bundles push Potential (buildable) stock |
Order import | Amazon → Katana | New FBM orders arrive as open sales orders tagged "Amazon FBM" - never later than 5 minutes |
Fulfillment + tracking | Katana → Amazon | Delivered status, carrier, and tracking number written back to the Amazon order |
FBM orders are imported as open sales orders - they appear in the Sell screen's Open tab tagged "Amazon FBM", ready to pick, pack, and ship (including in the Warehouse App)
Katana pushes stock levels to your FBM listings in real time, so listings stay accurate and you avoid overselling
Tracking numbers and delivery status are written back to the Amazon order when you fulfill - protecting your Valid Tracking Rate and seller metrics
Products are linked using SKU mapping (aliases) or imported from Amazon - one Katana product can carry both its FBA and FBM Amazon SKUs, so dual-SKU sellers keep a single source of truth
Orders are fulfilled from an existing Katana location that you choose - FBM doesn't add a new location
How FBM differs from the FBA integration
With FBA, Amazon holds your stock and ships for you, so data flows one way - from Amazon into Katana. With FBM, you hold the stock and ship yourself, so the flow is two-way:
| Amazon FBA | Amazon FBM |
Who ships | Amazon, from a fulfillment center | You, from your own location |
Inventory | Pulled from Amazon into a dedicated FBA location | Pushed from your Katana location to Amazon in real time |
Orders | Shipped orders import as Delivered | New orders import as Open - you fulfill them |
Tracking | Handled by Amazon | Added in Katana and written back to Amazon |
Requirements
To connect this integration, you will need to have a couple of things prepared beforehand, such as:
An Amazon Seller Central Professional Selling account
Active FBM (merchant-fulfilled) listings on your Amazon Seller account
A Katana location to fulfill FBM orders from (any location except an Amazon FBA location)
Integration setup
Initiate a connection
Connect Amazon FBM from its own tile in the Integrations Marketplace
If Amazon FBA is already connected, your existing Amazon authorization is reused - no second login
Choose the Katana location your FBM orders are fulfilled from
Product mapping and importing
Products are matched by SKU between Amazon and Katana
If your Amazon FBM SKUs differ from Katana SKUs (for example, separate FBA and FBM SKUs for the same product), map them with SKU aliases
Import products from Amazon to complete product mapping. This step is required for the inventory push and order import to work properly
Choose the stock value sent to Amazon
Pick whether Katana pushes In stock (default) or In stock + Expected quantities to your FBM listings
