Shop Management Software Built for Independent Repair Shops
Run estimates, digital inspections, repair orders, invoices, scheduling and payments in one place — without enterprise pricing, complexity, or a drawn-out setup project.
Brake inspection
2019 Ford F-150
Document the issue, send the estimate and keep the approval tied to the job.
Built for how a shop actually runs
The four things that touch every job, done right.
Show them what you found — don't just tell them
Attach photos and video straight to the estimate or invoice. Customers can actually see the worn brake pad or the leaking hose before they approve the work, not just take your word for it.
A flagged issue, tagged and attached directly to the customer's estimate.
From estimate to invoice in one click
Build an itemized estimate, send it to the customer for approval online, then convert it straight to an invoice once the work's done. Shop fees, taxes, and compliance fields are already built in.
Get paid without chasing anyone down
Email a secure payment link and the customer pays online, no terminal, no waiting on a check. The money goes straight into your shop's own Stripe or Square account, never through us.
Paid Online
Deposited to the shop's own account
Know where every job actually stands
Assign a job to a tech and track it from drop-off to done. No more walking the bay to ask where things stand on a given car.
Everything an independent shop actually needs
No modules to unlock, no per-seat tax, no tiers to negotiate. It's all in.
Invoicing & Estimates
Itemized line items, shop fees, taxes, and compliance details built in. Send estimates for customer approval online, then convert straight to an invoice.
Online Payments
Customers pay their invoice online through a secure link, powered by Stripe or Square. Money goes straight into your shop's own account — never through us.
Digital Vehicle Inspections
Attach photos and video to any estimate or invoice so customers can see exactly what you found.
Appointment Scheduling
A real calendar with month, week, and day views, plus an at-a-glance view for what's on deck today.
Repair Order Tracking
Assign jobs to techs and track status from drop-off to done, right alongside the invoice.
Customer & Vehicle History
Every customer, every vehicle, every past service — searchable in seconds from anywhere in the app.
Reviewing an inspection together before the customer approves the work.
Built by someone who knows the industry
Underhood is built by a founder with 25 years in the automotive industry — not a software company that's never set foot in a shop. The goal is simple: software that fits the way an independent shop actually works and stays capable as the business grows.
Built for the mobile automotive tradeThe work moves. Your software should too.
Phone-first business software for detailers, PDR techs, wheel repair, mobile paint, reconditioning, and other automotive trades that do the work where the vehicle is.
$29/month per business — first month free
Runs entirely from your phone
Create a job, add services, and run your whole day from your pocket — no laptop, no office.
Walk the lot in one trip
Log every car for one dealership account in a single visit, then send one link that gets all of them approved at once.
Sign-off on the spot
Hand over your phone for an on-site signature, or send a link instead — either way it's dated and documented.
Get paid before you leave
Send a payment link on the spot through your own Stripe or Square account — the money is yours, we never touch it.
Straightforward pricing
Two focused products. No surprise add-ons.
