Case Study: GJ Motorsports achieves 4 hours/week admin savings and automated order-to-shipping with Katana

How GJ Motorsports saves 4 hours of weekly admin with Katana API automations

GJ Motorsports, a Chicago-based aftermarket automotive parts manufacturer specializing in pickup truck lighting, needed real-time inventory and make-to-stock manufacturing control plus reliable e-commerce integration to avoid stock-outs and reduce manual admin. They chose Katana—using its manufacturing ERP, Shop Floor App, API and Zapier connectivity—to commit items to sales orders, track materials and build custom integrations with their OpenCart storefront.

Using Katana’s Shop Floor App, API and Zapier automations (with Easy Insight reporting), GJ Motorsports automated order management, shipping and shop-floor workflows—routing orders to QuickBooks and ShipStation, triggering manufacturing when stock runs low, and delivering weekly supplier inventory reports. The Katana-based solution reduced admin time by about 4 hours per week (roughly two workdays per month), gave live visibility across 222 products and 120 materials, improved on-time fulfillment, and freed the owner to focus on design and growth.
