The Smart Operating System for Auto Shops.
CarSignal is a shop management platform for independent auto repair shops. We replace the fragmented stack shops juggle today. Booking, intake, quoting, parts ordering, invoicing, payments, and customer communication all within one smart system. Instead of charging SaaS fees, we monetize through a 1% fee on the payments rail, so shops switch off $500+/month tools like Shopmonkey and Tekmetric without adding a line item. Every invoice paid through CarSignal is revenue; every shop that switches saves money on day one.
