GlassBiller

GlassBiller provides a specialized workspace to manage your auto glass business from any device. You can move away from paper-based systems by using a digital dashboard that handles everything from initial customer quotes to final insurance payouts. The platform focuses on reducing the time you spend on administrative tasks by automating the complex parts of the glass industry, such as looking up NAGS parts and calculating labor rates automatically.

You can coordinate your entire team with a drag-and-drop calendar that syncs with technician mobile devices for real-time updates from the field. It simplifies the often-frustrating process of insurance billing by integrating directly with major providers, ensuring your claims are submitted correctly the first time. Whether you operate a single mobile unit or a multi-location shop, you can track your profitability and manage customer relationships without switching between multiple tools.
