If you're selling through Shopify or WooCommerce and fulfilling everything through ShipBob, the native app connections cover the core loop well: orders flow into ShipBob automatically, inventory counts sync back to your store, and tracking numbers land on the order once a shipment goes out. That's real, working integration, not a half-built placeholder.
For a lot of smaller operations running one sales channel, that's genuinely the whole job. The gap tends to open up once there's more than one channel pulling from the same ShipBob inventory, or once a system outside the standard Shopify or WooCommerce pairing needs to see the same data.
