How to Evaluate Glass Shop Performance in Your TPA Network
Not all shops in a TPA network perform equally. Identifying top performers and addressing underperformance requires consistent measurement across key metrics.
Response time is the first indicator. How quickly does the shop contact the policyholder after receiving a dispatch? Shops that consistently respond within two to four hours demonstrate operational discipline and customer focus.
Documentation completeness measures process quality. Shops that submit invoices with all required NAGS numbers, photos, and supporting documentation on the first pass are easier and cheaper to work with. Track first-pass approval rates.
Invoice accuracy reflects billing integrity. What percentage of a shop invoices require pricing corrections? Shops with low adjustment rates understand the program and bill correctly. High adjustment rates may indicate training needs or intentional over-billing.
Customer satisfaction connects everything. Whether measured through post-repair surveys, complaint tracking, or carrier feedback, customer satisfaction is the ultimate measure of shop quality.
Volume consistency shows reliability. Shops that accept dispatches consistently and complete them on schedule are more valuable than those that cherry-pick jobs or frequently decline work.
Use these metrics in quarterly network reviews. Share performance data with shops so they know where they stand. Recognize top performers publicly and work constructively with shops that need improvement. If improvement does not happen, be prepared to replace underperforming shops.
