Use cases by sector
Garages and automotive services
Approved estimates, warranted parts and customers who do not remember authorising anything.
The classic garage argument is not technical: it is about what was authorised. The customer remembers a figure, the garage remembers a phone call, and nothing is in writing because the vehicle was on the lift and a decision was needed there and then.
The three moments worth putting in writing
- 1
Reception
Vehicle condition, mileage, what the customer asks for and what you observe. With photos.
- 2
Repair authorisation
Amount, scope and acceptance. It prevents 90% of arguments.
- 3
And the extension, if something turns up
A second scope accepted, not a phone call each side remembers differently.
Important
The third causes the expensive complaints. Another fault appears with the vehicle stripped, the customer is phoned, work continues — and the final invoice doubles the estimate the customer does remember. An acceptance from a phone at that moment costs a minute.
What the garage gains besides avoiding rows
| Element | What it is for later |
|---|---|
| Reception photos | Pre-existing damage later blamed on the garage |
| Authorisation with an amount | Non-payment and consumer complaints |
| Traceability of the fitted part | Claiming from the supplier if it fails under warranty |
| History per vehicle | Seeing what was done last time without digging through paper |
Watch out
The third row recovers the most money and is kept the worst. When a part fails under warranty, claiming from the supplier requires knowing which reference was fitted, when, and to which vehicle. If that only exists on a purchase invoice, the claim is lost for lack of traceability, not for lack of merit.
What can be automated without complications
Worth knowing
It applies equally to commercial vehicle workshops, agricultural machinery, marine and in-house fleets. The machine changes; the authorisation and warranty problem is identical.
›Must the customer install anything to accept?
No: they get a link, read it and accept from their phone.
›Does a phone acceptance count as evidence?
Yes, and considerably better than a call each side remembers.
›What if the customer does not reply?
They are reminded automatically; until they accept, the work is not extended.
