You can connect multiple WooCommerce stores to your Katana account.

The option to connect another store becomes visible on the "Settings" -> "Integrations" page after connecting the first store.

To connect each additional store, you can follow exactly the same connection guide as for the first store.

The integration works exactly in the same way for each store. Sales order sync, product and customer import and matching, and stock sync work identically for all stores. For example, if the same product (i.e. same SKU code) exists at multiple stores, then the stock levels would be synced from Katana to all the WooCommerce stores that include that product.
