That number is the cost of not being able to prove what you installed. WorkSiteCam timestamps and geotags every job photo — so a false warranty claim ends at your phone, not your bank account.

Opportunity-cost model: each warranty hour pulled from a billable job at $50/hr avg lost margin. Real-world callback patterns concentrate on specific crew/material/job-type combos — documenting them is the highest-leverage fix.
