    The problem

    Proof of work is scattered across phones and chats

    Photos get taken, but the right ones rarely reach the right client with the right context. When a question comes up, nobody can find the evidence.

    2. WhatsApp
    3. Scattered files
    4. Manual forwarding
    5. Client confusion

    Every photo is proof

    Not just a photo. A record that can't quietly change.

    Every photo records who took it, when, and a unique fingerprint so it can never be swapped later. Anyone can open the original in full size. If a photo really needs removing, an owner or admin has to approve it. Nothing disappears silently.

    What it does

    Everything a job needs, in one place

    Real screens from the ProofTrail Android app, showing the same data you see on the web.

    Evidence templates you control

    Set once which photos each kind of job needs, area by area, before and after. Every job then follows the same checklist.

    A gallery of proof, not a photo dump

    Photos are grouped by area and task, before against after, so a client or inspector can see the work in seconds.

    Every property on the map

    See which properties have work today, which have open jobs and which need nothing. Then open directions from the same screen.

    Issues resolved against the evidence

    A client raises an issue on the exact task. Whoever fixes it sees the original evidence, and proves the fix the same way.

    Works with no signal

    Jobs, checklists and evidence are saved on the phone. Nothing is lost offline, and nothing is shown as sent until it actually is.

    The right alert, to the right person

    A job submitted, a client issue or a fix ready to check can each notify a phone, send an email, or both, for each person.

    Web + Android

    The same business, wherever you check it

    Owners and admins see every web section on the phone: the same dashboard, jobs, clients, map and reports. Staff see their own work: today's jobs, their issues and their alerts.

    How it works

    One trail from the job site to the client and back

    Capture → Verify → Prove → Resolve → Retain.

    1. 01

      Capture

      Workers take exactly the photos the job template asks for, on the web or the Android app, with or without signal.

    2. 02

      Verify

      Coverage is checked against the template before a job can be submitted.

    3. 03

      Prove

      A proof report goes to the client by a secure link, or as a PDF.

    4. 04

      Resolve

      Clients raise an issue on the exact room or task, and the fix is proven the same way.

    5. 05

      Retain

      Evidence, approvals and an audit trail stay together as one durable record.

    Documentation

    Compliance-ready documentation, without the overpromising

    Every status change, assignment and approval is timestamped and attributed, so the record holds together on its own. ProofTrail does not provide legal advice or certification and cannot guarantee any outcome in a dispute. Check what your location and your clients require.

    Client approvals are recorded on the job, next to everything else that happened on it.
