Auto repair is adversarial because the information is asymmetric.

As with home services, the headline number depends on scope: IBISWorld puts the US auto mechanics industry at $92.1 billion in 2026, while broader definitions of automotive repair and maintenance reach several times that by including parts, tyres, collision and dealer service. The count of businesses is the more stable figure, and it describes a market of roughly 307,000 operators, nearly three-quarters of whose revenue sits with independents rather than national chains.

Independents are the structural majority and the structurally underserved. They compete against dealer service departments with far better software, and against aggregators whose business model requires them to stay between the shop and the driver.

The diagnostic moment is the leverage point. A driver with a warning light or a noise wants to know what is probably wrong, what it should cost, and whether it can wait. Answering that honestly and for free is cheap to do well with modern models, and it converts a frightened customer into an informed one before they ever reach a shop.

Having closed the gap, charging the shop for the introduction would reopen it. The durable revenue is the operating software behind the bay — scheduling, quoting, the phone, payments, multi-location reporting — sold to a shop that has already watched customers arrive at no cost.
