Shipwire is a warehousing and order fulfillment service. Shipiro is a third-party service that takes your order information out of BigCommerce and syncs it to your Shipwire account for fulfillment.
Once your orders ship from Shipwire's warehouses, Shipiro then pulls the tracking information out of Shipwire and syncs it back into BigCommerce. The service has a lot of nice features such as multi-ship, duplicate order detection, detection of non-shippable products, and full technical audit information. Neither BigCommerce nor Shipwire developed Shipiro so we ask that you send your connection related questions to the Shipiro team.
