Book it. They check in. You keep the record.

One link puts the hirer's checks, your agreement and the deposit on one record. Sample data.

  3. 03The record

    The sealed hire record on a phone, every section on record, on sample data

    The car is back. Closing the hire seals the record.

The evidence exists. It is just everywhere.

Who drove, what they signed, what was held, what the car looked like. Without one system it is spread across phones, paper and message threads, and hardest to find on the day someone asks.

Booked Friday. Sealed Tuesday. Every step timed.

When a hirer, an insurer or an authority asks what happened, the answer is one record, not a search.

KeyProof keeps the evidence together. It does not decide who is at fault, and it is not insurance. Where it stops

You run the hire. They carry the pass.

The booking lives on your phone. The hirer needs no app and no account, and keeps a hire pass until the car is back.

One firm never sees another firm's hires.

What protects a hire record today. Read about security

Tenant separation
A request for another firm's hire is refused and logged.
Tested every release
Isolation tests call the real routes as two firms. A release cannot deploy without them.
Identity documents
ID images stay with Stripe. KeyProof keeps only the result.
Insured
Professional indemnity and cyber cover with Hiscox. The company's own, not cover for hirers.
