Netsuite is a cloud-based ERP system that provides merchants with all the tools they need to run their business.
ShipStation's official integration to Netsuite is through Nova Module. This module is used to export orders from Netsuite into ShipStation, update Netsuite orders when shipments are created in ShipStation, and update products in ShipStation to match Netsuite.
To get started with the integration process, review the SuiteApp ShipStation page and click the Contact Me link to discuss details with one of ShipStation's Channel Sales managers.
