The Insurance Carrier Guide to Glass Shop Network Management
The glass shop network is the delivery mechanism for your entire glass program. Every policyholder interaction, every repair, every ADAS recalibration — it all happens through your network shops. How you build, manage, and optimize that network determines the quality and cost of your glass program. This guide covers the complete network management lifecycle.
Network Design: Coverage, Density, and Capacity
Effective network design starts with understanding your claims geography. Where are your policyholders located? Where do they drive? Where do claims occur? Map your claims data against shop locations to identify coverage gaps — areas where policyholders have no nearby network shop — and over-served areas where multiple shops compete for limited volume.
Network density should be proportional to claims volume. Urban areas with high claim concentration may need multiple shops to handle volume without delays. Rural areas may need fewer shops but with broader mobile service coverage to reach dispersed policyholders. The goal is that every policyholder can access a qualified network shop within a reasonable distance and timeframe.
Credentialing: Setting the Quality Bar
Every shop in the network should meet minimum credentialing standards before receiving any dispatches. These standards should include current general liability insurance with minimum coverage of one million dollars per occurrence, current garage keepers insurance, AGRSS registration or equivalent installation quality standards, trained and certified technicians, and adequate facilities and equipment for the types of work being performed.
For shops performing ADAS recalibration, additional credentialing should include verified calibration equipment from approved manufacturers, documented calibration procedures for the vehicle makes being serviced, adequate indoor space for static calibration with proper dimensions and lighting, and technician training specific to ADAS systems.
Performance Management: Measuring What Matters
Once shops are credentialed and receiving dispatches, ongoing performance management separates good networks from great ones. The metrics that matter most are response time, which measures how quickly the shop contacts the policyholder after dispatch, scheduling time measuring how quickly the work is scheduled, completion time measuring how quickly the work is finished, documentation quality measuring the first-pass invoice approval rate, and cost efficiency measuring the average total claim cost compared to network benchmarks.
These metrics should be tracked continuously, reported quarterly, and used in annual network reviews. Shops that consistently exceed expectations should be recognized and rewarded with dispatch priority. Shops that consistently underperform should receive coaching with clear improvement expectations and timelines.
Communication and Relationship Building
The best shop networks are built on relationships, not just contracts. Regular communication about program changes, pricing updates, documentation requirements, and performance expectations keeps shops informed and engaged. Annual or semi-annual network meetings create opportunities for face-to-face interaction, feedback collection, and relationship strengthening.
Two-way communication is especially important. Shops on the front lines see things that the TPA and carrier may miss — emerging fraud patterns, parts availability issues, new vehicle challenges, and policyholder feedback trends. Creating channels for shops to share this intelligence improves the entire program.
Network Optimization: Continuous Improvement
A shop network is never finished. Vehicles change, coverage areas shift, shops open and close, and performance varies over time. Annual network reviews should assess geographic coverage against current claims patterns, evaluate individual shop performance against benchmarks, identify shops for recruitment in underserved areas, and remove shops that have failed to meet performance standards after coaching.
The carrier and TPA should also monitor industry trends that affect network requirements — ADAS technology evolution, EV growth, new vehicle designs with specialty glass, and changes in shop business models. Proactive network evolution positions the program to handle future challenges before they become service problems.
