Revenue recovery for collision repair

Supplements are the leaking bucket for shop revenue.
Not anymore.

WrenchWriter builds your insurance supplements in minutes, every line cited to OEM and industry-standard repair data.

Built 100% for the shop and the customer.

Everything your shop needs for supplements.
In one platform.

Today, writing a supplement means working across fragmented systems, portals, and data sources to find the right references. Every minute spent hunting is a minute pulled away from estimators assessing new vehicles and delivering customer satisfaction.

WrenchWriter ties it all together. It cross-references the job against OEM procedures and industry-standard repair data, surfaces the operations that aren’t included, and presents a complete, cited draft for your estimator to review and approve. Saving time, capturing missed revenue, and decreasing carrier touch-points.
