What the Katana–Longtail integration does

Longtail is a third-party logistics provider that offers warehousing, inventory management, and order fulfillment services, supported by its own warehouse management system (WMS).

By connecting Katana with Longtail, you can:

  • Map Longtail warehouses to Katana locations: Each Longtail warehouse is linked to its own dedicated Katana location, and only mapped warehouses sync.

  • Import products by SKU: Longtail products match existing Katana products by SKU, unknown SKUs create new products, and SKU aliases can bridge mismatched SKUs.

  • See Longtail stock levels in Katana: Longtail's stock numbers appear as read-only External inventory at each warehouse's mapped Katana location.

  • Reconcile inventory: Katana compares its in-stock quantities with Longtail's on hand quantities and creates stock adjustments for any differences.

How your daily workflow looks

  1. Longtail receives, stores, and manages your stock in its warehouses.

  2. Longtail products are imported into Katana by SKU. Existing products are matched, and unknown SKUs create new products.

  3. Longtail's on hand stock levels update as read-only External inventory at each mapped Katana location.

  4. On a schedule or on demand, Katana reconciles its in-stock quantities against Longtail's on hand quantities and creates stock adjustments for any differences.

  5. You plan production and purchasing in Katana using the up-to-date stock picture.
