Stop getting questioned. Start sending proof.
When a customer calls two weeks later saying the problem wasn't fixed, you need more than your word — you need timestamped documentation that was built before you left the driveway.

What is a mobile mechanic service report?
A mobile mechanic service report is a professional record of an on-site vehicle repair that documents the customer's complaint, the diagnosis, the work performed, the parts used, and the test results that prove the fix. It gives the customer a clear account of the job and protects the mechanic if the repair is ever questioned.

The problems every Mobile Mechanic faces
Customers dispute work they can't see
You replaced the alternator, tested the charging system, and drove it 10 miles to confirm. But if you didn't document it, you have nothing to show when they call back saying it 'still doesn't feel right.' Mobile mechanics lose more money to undocumented disputes than almost any other trade.
Explaining labor time to non-mechanics is a losing battle
Customers see 45 minutes of wrench time and forget the 2 hours you spent diagnosing, sourcing the part, and road-testing. Without a clear breakdown of what you found, what you did, and why it took as long as it did, the invoice always looks high.
Getting referrals from invisible work
You drove to their house, fixed a hard-to-diagnose idle surge, saved them a $600 dealer bill, and left. They were happy. But they have nothing to show their neighbors. There's no business card, no report, no proof you exist — and that referral never happens.
WorkReceipt fixes it
Here's how WorkReceipt fixes it
Every repair documented before you leave
Snap the before and after, voice-note what you found and what you did, and WorkReceipt generates a professional customer report with AI — right there in the driveway. They get a link before you pull away.
AI explains the work in plain English
You say 'replaced the MAF sensor, cleaned the throttle body, cleared codes.' WorkReceipt turns that into a customer-facing summary any non-mechanic can understand and appreciate — without you writing a word.
Reports customers forward to their neighbors
A professional branded report with your business name, photos, and a summary of what you fixed travels. Customers share them. That's how word-of-mouth compounds for mobile mechanics who document their work.
What your customer receives
Here's what a WorkReceipt looks like
A sample report — yours is built from your own job photos and a quick voice note, in about 60 seconds.
No-Start Diagnosis + Fuel Pump Replacement
Vehicle arrived as a no-start. Performed full diagnostic including fuel pressure test, battery load test, and code scan. Identified failing in-tank fuel pump producing only 22 PSI (spec: 55–65 PSI). Replaced pump assembly and filter, re-tested at 61 PSI, and confirmed clean start with multiple ignition cycles. Vehicle restored to full operation.
Work Performed
- OBD-II code scan — P0087 (fuel pressure low) confirmed
- Fuel rail pressure test: 22 PSI (well below 55 PSI spec)
- Battery load test passed at 625 CCA
- Removed and replaced in-tank fuel pump assembly (Delphi OEM-equivalent)
- Replaced inline fuel filter
- Post-repair pressure test: 61 PSI — within spec
- 10-minute test drive with no returned codes
Spark plugs at rear of engine show moderate wear. Recommend replacement at next service interval (or approximately 8,000 miles) to maintain optimal fuel efficiency and prevent misfires.
This is an example. Real WorkReceipts are generated by AI from your own voice note and photos — in about 60 seconds.

Questions
Mobile Mechanics: frequently asked questions
Can I document the diagnostic codes and test results, not just the repair?
Yes. Add the fault codes you pulled, the readings from your gauges or meter, and the test results after the fix — WorkReceipt's AI writes them into a clear before/after summary that shows the diagnosis, not just the finished job.
How do I show the customer which parts I used?
Note the part and brand in your voice note or notes field — 'Delphi fuel pump, OEM filter' — and it appears in the work-performed list and the invoice description, so the customer sees exactly what went into the repair.
How does this help if a customer says the repair didn't fix the problem?
A timestamped report with your diagnostic readings, the part replaced, and the post-repair test (pressure, code scan, test drive) is exactly the record you need when a customer disputes whether the work was done. It's a lot harder to argue with a documented 61 PSI reading than a memory.
Can a customer approve or sign off on the repair from their phone?
Yes. Every report includes a share link the customer can open on any phone — no app — and they can tap to accept the completed work, which is timestamped for your records.
Do I need to type up the report myself?
No. Snap the before/after photos, say what you found and fixed, and the AI writes the customer-facing summary in about 60 seconds — you review and send from the driveway.
