Service history app
Build a Service History That Sells Your Car for More.
Used-car buyers pay extra for cars with proof of care. Maintory builds that proof — quietly, over years — and exports it as a polished PDF when you're ready to sell.
Why service history matters at resale
When two near-identical used cars sit side by side, the one with a documented service history almost always sells faster and for more. Industry surveys consistently estimate that a complete service record can add 5–15% to a private-sale price, depending on the vehicle and the buyer's diligence.
The reason is simple: a buyer can't inspect the inside of an engine. What they can do is read a list of every oil change, every brake job, every coolant flush — and decide that the car was cared for. That piece of paper is the cheapest insurance against being lowballed.
What a good service history contains
- Every routine service with date and mileage — oil, filters, tires, brakes, fluids.
- Every non-routine repair — what broke, when, where it was fixed.
- Receipts or invoices (or photos of them) for the bigger items.
- Mileage progression showing you didn't roll the odometer back.
- One clean summary page so the buyer can grasp the story in 30 seconds.
Maintory generates this automatically. Every service entry and expense you've logged becomes part of a chronological record. The PDF export bundles it into a single, polished document with totals, category breakdown, and a clean timeline.
Start now, even if you're not selling for years
The best time to start a service history was when you bought the car. The second-best time is today. Even a partial history — the last 12–24 months — is better than nothing, and most buyers care more about recent care than ancient records.
Maintory makes adding past services trivial: tap the date, pick a category, enter the mileage, done. You can backfill a year of service in about 10 minutes from a glove-compartment stack of receipts.
How Maintory handles service history
- Per-car timelines. Every service belongs to a specific car. If you switch cars, history doesn't get tangled.
- Reminders that turn into history. Mark a reminder as complete and it slides into the completed-service log automatically.
- Photo attachments (Premium) for receipts and invoices — invaluable when a buyer asks "got proof?"
- PDF export (Premium) — a polished document ready to email, AirDrop, or print.
- Anonymous auth. Your data is yours; no signup, no account creation, no shared servers analyzing your driving.
