What the Katana–The Fulfillment Lab integration does
The Fulfillment Lab provides third-party logistics services through its Global Fulfillment System (GFS™). The system supports ecommerce order fulfillment, inventory management, shipment tracking, and international fulfillment.
By connecting Katana with The Fulfillment Lab, you can:
Import orders as sales orders: Each The Fulfillment Lab order becomes a Katana sales order, with a fulfillment, carrier, and tracking number for each shipped package.
Import products by SKU: Matching SKUs link to existing Katana products, and SKU aliases can connect SKUs that differ between the two systems.
See stock levels at mapped locations: The Fulfillment Lab stock appears in Katana as read-only external inventory at each warehouse's mapped location.
Track inbound shipments as stock transfers: Each inbound shipment becomes a Katana stock transfer that updates as The Fulfillment Lab receives the goods.
Map warehouses to locations: Each The Fulfillment Lab warehouse links to its own dedicated Katana location.
