# RO Engine > RO Engine is shop management software for independent auto repair shops, built by a working shop owner. Its tagline is "The estimate that explains itself": the AI writes the maintenance recommendations on every repair order, and the customer's estimate explains each service in plain language — what it is, why it's due now, and what happens if they wait — written for the customer's own vehicle and sent to their phone. Customer education is the hardest part of selling maintenance; RO Engine does it on every car. One plan: $349/month, everything included, unlimited users, month to month. Each shop gets its own live copy of the app at its own address (yourshop.roengine.com), set up in minutes, free for 90 days. ## What it does - **AI service recommendations on every repair order** — cross-checks the manufacturer maintenance schedule (54,000+ OEM service intervals), the vehicle's own history and known failure patterns; surfaces overdue and coming-due work, remembers deferred work from past visits, and explains it in plain language. Advisors choose normal or severe service schedules. - **AI phone answering** — answers when the counter is busy, takes vehicle and customer details, and puts the call transcript on the customer record. Included, not an add-on. - **Two-way texting** with a local shop number and click-to-call. - **Digital estimate approval** — customers approve or decline line by line from a private link (no app, no login), with an AI-written explanation of each service ("What is it?", "Why now?", "What happens if you wait?") and a diagram of the car showing where each service is; declines are saved as deferred work for the next visit. - **Full comparison** with Tekmetric, Shop-Ware, Shopmonkey, AutoLeap and Mitchell 1 SE: https://roengine.com/compare/ - **Parts and purchase orders** — parts attached to the job, purchase orders and receiving, core charges and returns, margin visible before approval. - **Photo intake** — VIN from the door jamb sticker, mileage from the dashboard, plate capture, timestamped condition photos. - **Multi-point inspections** — green/yellow/red ratings with photos; tech notes rewritten for customers; red findings become recommendations. - **Oil-change decals** — next service calculated from the actual oil spec and OEM time interval, printed automatically. - Work orders, invoicing, customers, vehicles, scheduling and reports. ## Pricing - $349 per month, one plan, every feature on from day one.

Every feature runs in his own shop every day before it ships. ## Key pages - [Home](https://roengine.com/): product overview, pricing, free trial - [Start a free trial](https://app.roengine.com/signup): set up your own shop - [The shop owner's fact sheet](https://roengine.com/card-fees/): how payment processing fees fund much of the shop software industry, with sources - Contact: joe@roengine.com
