The table below summarizes the data exchanged between Katana and Warehance.

Connect Warehance from Katana's Integrations page. Click Connect and enter your Warehance API key. When the connection is approved, the configuration screen opens on the Location tab.

Each Warehance warehouse maps to its own dedicated Katana location. Click Add to Katana to create that location automatically. Until then, a warehouse that was never mapped shows Not mapped.

To pause a mapped warehouse, click Unlink. Its status then shows Unlinked. Click Relink to resume it. Only mapped warehouses sync.

Nothing syncs until you click Activate sync in the header.

Product mapping creates a required link between each Warehance product and a Katana item. Products are imported by SKU:

You choose how SKUs are matched: direct 1:1, or through SKU aliases.

Kits and bundles from Warehance become Katana products. Add a bill of materials (BOM) with their components in Katana. On orders, a kit line stays a single sales-order row.

A SKU alias links a Warehance SKU to a different Katana SKU. Use aliases when the same product has mismatched SKUs in the two systems. Upload your SKU alias mapping before importing products, so those products link to the correct Katana items.

Orders import once they reach the configured import-from status, which is the Open state by default. After import, they keep updating automatically through every later status change.

Each Warehance order becomes one Katana sales order, with one row per order line. The order source is set to Warehance.

Each shipped package becomes a Katana fulfillment with its carrier and tracking number. Multi-package shipments create one fulfillment per package. Together, these fulfillments never exceed the ordered quantities.

If an order is canceled in Warehance, it is deleted in Katana only if the sales order is still open.

When a Katana sales order reaches the Ready for fulfillment status, it is pushed to Warehance as an outbound order. Its progress then syncs back to Katana like any imported order.

Canceling the Katana sales order does not cancel the pushed Warehance order. Changes you make in Katana after the push do not update the Warehance order.

Warehance stock levels appear in Katana as read-only External inventory at each warehouse's mapped location. The number shown is Warehance's On hand quantity. You can't edit these numbers in Katana.

Reconciliation compares Katana's in-stock quantity against Warehance's on-hand quantity. It runs on a schedule or on demand. For any difference, it creates a stock adjustment in Katana.

Each Warehance inbound shipment becomes one Katana stock transfer. The transfer number is the PO number when one exists; otherwise it's the inbound ID.

Stock transfers follow the inbound's status, and received quantities update the transfer. Katana stock transfers have two states: in transit and received. Partial receipts appear as updated expected and received quantities until the shipment is fully received.

If an inbound is canceled, its stock transfer is deleted.

To disconnect, open Katana's Integrations page, select the Warehance integration, and disconnect it.

Syncing stops immediately: no new orders, fulfillments, inventory updates, or inbound shipments come in, and no sales orders are pushed to Warehance.

Records already imported into Katana stay in place, including sales orders, fulfillments, products, and stock transfers.
