Case Study: Glass Doctor of Charlotte boosts profits 10% and improves efficiency with RingCentral

RingCentral Helped This Small-Business Franchisee Boost His Company’s Bottom Line, Increase Efficiency, and Improve its Already-World-Class Customer Rating

Glass Doctor of Charlotte is a 35-employee franchise in the construction/service industry (founded 1987, HQ Matthews, NC) known for a world-class Net Promoter Score of 81. Despite strong reputation, the business relied on legacy phone lines that slowed response times, increased employee stress, and limited real-time communication—threatening service consistency in a competitive market.

Migrating to RingCentral and RingCentral Video delivered an intuitive, all-in-one platform (calls, voicemail-to-text, call recording, mobile number transfer, team messaging, and video meetings) that staff adopted quickly. The solution improved scheduling, training, and inter-franchise collaboration, boosted operational efficiency by about 10%, and strengthened customer service and the company’s bottom line.
