How to import and fulfill orders from Amazon FBA

The Amazon FBA integration allows Shipped orders to be sent to Katana as Delivered orders.

If you've activated your integration, Katana will check every minute for newly shipped orders and automatically import them. Only shipped orders are imported (pending, unshipped, canceled, and unfulfillable Amazon orders do not sync to Katana).

Orders sync one-way — from Amazon FBA to Katana as sales orders (SOs).

Katana imports all orders that meet both of these conditions:

  • The order status is Shipped

  • The order type is FBA (Fulfilled by Amazon)


What happens when orders import

If a shipped Amazon order is detected by Katana, the following steps will happen automatically:

  1. Fetches order data from Amazon, including line items.

  2. Matches products by checking each SKU against your Katana variants.

    1. If SKU aliasing is not used: matches amazon seller SKU directly against the Katana variant SKU

    2. If SKU aliasing is used: each product is matched based on the mapping

  3. Creates an SO in Katana with all line items, prices, and tax data (depending on the marketplace, and whether tax data is available or not).

  4. Creates a fulfillment record linked to the SO, showing which items were shipped.

  5. Creates a stock movement that reduces inventory from the mapped FBA location.

  6. Sets the order status to Delivered.

Because Amazon FBA handles the actual shipping, orders arrive in Katana fulfilled — there's no picking, packing, or shipping step needed in Katana.


How tracked items are managed

Katana handles batch-tracked, serial-tracked, and regular items differently during fulfillment:

  • Batch-tracked items: Fulfillment creates a batch stock transaction using the FIFO method from available batches.

  • Serial-tracked items: Fulfillment creates serial stock transactions. If serial data isn't available from Amazon, the order is flagged with a missing tracking data notice.

  • Regular items with serial numbers: If Amazon provides serial numbers for a non-serial-tracked item, Katana will try to match them to existing serial records.

    • Unmatched serial numbers are saved as order row attributes, and the order is flagged.

Order sync has no configurable settings — shipped FBA orders are imported automatically once the integration is active.

If multiple Amazon marketplaces are connected to Katana, each marketplace syncs its orders to the Katana location selected during setup.
