    Some dealerships will outsource auto glass repair and replacement to 3rd party shops, usually because of time and cost constraints. These repairs can come in various forms, from windshields to rear windows and side glass.  While this process is still considered the most common practice, many dealership service centers are seeing the opportunity for bringing glass repair in house, allowing profits to stay with the dealership.

    A company that has years of experience assisting dealerships and auto glass repair and replacement companies become more profitable, Mainstreet ™ has a tool specific for the auto dealership Service Center. GMS, Glass Management SaaS (software-as-a-service) is the one go-to Point of Sale (POS) Auto Glass Repair and Replacement Software providing confidence in procuring the right glass for your customer’s vehicle.  


    Today, some Insurance policies may require that windshield replacement be done using OEM glass for cars which are less than two years old. From any internet enabled device, GMS provides dealerships with quick access into the NAGS (National Auto Glass Specifications) database lookup feature. This simplifies glass identification further through the VIN Decoder, which  verifies a vehicle's make, model and year at one time. This has proven to be time saving and eliminate confusion on what to order. From ordering glass to managing inventory GMS provides quick look ups for integrations with Pilkington, PGW, Mygrant Glass, and more without having to leave GMS software interface.


    Michael Casella, Executive Vice President elaborates, “Glass repair professionals have been trusting Mainstreet for over 39 years with top-notch point of sale solutions for glass repair and replacement professionals. Today, we are thrilled to empower dealerships on how to cost-effectively run their glass replacement service as a value-add, all while training and supporting the entire software adoption process” 


    Additionally, the glass software is integrated with CDK Global, enabling a smooth transition to one of the most popular dealer management software systems used by dealerships. A popular feature is the insurance integration that sends invoices through secured EDI to all major insurance carriers. 


    “Many body shops struggle with automation for insurance billing many times causing a cog in their productivity, or more of an issue-not getting paid on time. Our dealerships love us because they can schedule jobs, order inventory, and process claims all in one place. Invoices go right to the insurance companies helping our clients get paid quickly.” Contributes Mark Haeck, Sales Manager, GMS.  

    To process non insurance payments, GMS offers a meet or beat merchant processing system, Glas-Pay ™. This proprietary system enables direct payments for credit card transactions through the GMS software.


    With a fully comprehensive point of sale system, GMS provides the dealership with all the tools necessary for easy quotes, inventory control, scheduling, and billing customers directly as well as insurance - all with world class support, a no-call queue mantra, and award-winning customer service.
