Built around the hire, from booking to return.

For the owner of an independent hire firm: what KeyProof does at each point of a hire, and what stays your call.

Real product, sample data.

01Before the hire

Book it once. Send one link.

  • Enter the car, the dates and the hirer’s mobile once. If the car is already booked over those dates, you are warned before you confirm.
  • Save a draft without sending anything. A draft never counts as a booking.
  • The hirer gets one private link: no app, no account. They give their details, supply a DVLA share code and sign your agreement, and their photo ID is matched to a selfie through Stripe.
  • You check the share code on GOV.UK and record that you did.

02Handover

The car goes out with the evidence.

  • A guided walk of named photos, each timestamped and fingerprinted when it is taken.
  • A hire cannot be marked as on hire without a recorded deposit and the full handover photo set.
  • The deposit is a hold on the hirer’s card in your own Stripe account, or recorded as taken your way.

03During the hire

Today shows what needs you.

  • A car still out after its end date goes to the top, ahead of today’s collections and returns.
  • A penalty notice is matched to the hire that covers the offence date. Where none or several match, KeyProof asks you.
  • The hirer’s link becomes their hire pass until the car is back.

04Return

Back in, beside the photos it left with.

  • The same photo set at return, so the car’s condition out and back sits on one hire.
  • Releasing a deposit cancels the hold, so the money never leaves the hirer’s card. Keeping part of it needs a reason and a note.
  • Automatic release after a clean return is optional. A hire held as evidence is never released automatically.

05After the hire

The record stays.

  • Closing the hire seals the record as it stood.
  • Send an insurer a read-only link that expires after 30 days. You can revoke it.
  • Export a CSV of recorded payments and expenses for your accountant.

What KeyProof does not do.

So you know exactly where it stops.

Tracking
Overdue means past the end date. KeyProof does not track the car or its location.
Chasing
Chase opens WhatsApp with the message ready. You send it, from your own phone.
Damage
KeyProof records before and after. It never scores damage or decides whether a charge is fair.
Double-booking
A clash is a warning you can override, not a block.
Your money
Payments through Stripe settle to your own account. KeyProof never holds your money or takes a cut of a hire.
