Dead Simple Auto tracks every car you rent out — where it is, who has it, what it made, and what it quietly spent. Built for operators who outgrew a spreadsheet and don't want an enterprise contract.
Self-hostable. Your data stays on your hardware.
Most tools stop when the keys are handed over. The expensive part starts there.
Revenue minus expenses minus the loan, insurance and depreciation that run whether or not the car moved. Idle financed cars show their real loss.
A guided walk-around that maps every panel and rejects a photo that won't compare — so before and after are the same angle, and damage is provable.
Fuel, late return, mileage overage and toll charges become suggested deductions against the held deposit. Nothing is charged automatically.
Where every car is, where it's been, and geofences for the places it shouldn't go. Works with hardware you already have.
Import a statement, match each crossing to the rental that was driving, and pass it through. Cross-checked against the GPS trail.
Your own booking page, so a repeat customer doesn't have to cost you a platform commission.
You know the fleet made money last month. You don't know which three cars lost it.
The platform handles the booking. It doesn't do your books, and it won't defend you in a damage claim.
One stack you deploy yourself. Nothing phones home, and nobody else holds your customers' licences.

Dead Simple Auto is running a real fleet today. It is not yet a product you can sign up for, and it would be daft to pretend otherwise.
We're onboarding a small number of operators by hand. Leave an address and we'll be in touch — or just email hello@deadsimpleauto.com.
Thanks — opening your mail client so you can send it.
