When a question comes up, nobody can find the evidence. 1. Phone gallery 2. WhatsApp 3. Scattered files 4. Manual forwarding 5. Client confusion ![A single piece of evidence with capture time and fingerprint hash](https://stasx.com.au/assets/products/prooftrail/pt-m-evidence-detail.jpg) 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. Tamper-evident Every photo carries who, when and a fingerprint hash Audit trail Status changes, assignments and approvals are attributed Controlled removal Deleting a photo needs owner or admin approval Web + Android Owners see every section on the phone too 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. ![ProofTrail evidence templates list](https://stasx.com.au/assets/products/prooftrail/pt-m-templates-list.jpg) ### 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. ![ProofTrail evidence gallery with before and after photos](https://stasx.com.au/assets/products/prooftrail/pt-m-evidence-grid.jpg) ### 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. ![ProofTrail property detail with map pin](https://stasx.com.au/assets/products/prooftrail/pt-m-property-detail.jpg) ### 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. ![ProofTrail issue resolution screen](https://stasx.com.au/assets/products/prooftrail/pt-m-issue-resolution.png) ### 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. ![ProofTrail Android app working offline](https://stasx.com.au/assets/products/prooftrail/pt-m-offline-cache.jpg) ### 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. ![ProofTrail alert settings](https://stasx.com.au/assets/products/prooftrail/pt-m-notifications.png) 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. prooftrail-tau.vercel.app ![ProofTrail web evidence grid with before and after photos](https://stasx.com.au/assets/products/prooftrail/pt-w-evidence.jpg) ![ProofTrail Android map of properties](https://stasx.com.au/assets/products/prooftrail/pt-m-map.jpg) How it works ## One trail from the job site to the client and back Capture → Verify → Prove → Resolve → Retain. - 01 ### Capture Workers take exactly the photos the job template asks for, on the web or the Android app, with or without signal. - 02 ### Verify Coverage is checked against the template before a job can be submitted. - 03 ### Prove A proof report goes to the client by a secure link, or as a PDF. - 04 ### Resolve Clients raise an issue on the exact room or task, and the fix is proven the same way. - 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. ![ProofTrail audit log of status changes and assignments](https://stasx.com.au/assets/products/prooftrail/pt-m-audit-log.jpg) ## Give every completed job a proof trail Explore the live product, or talk to us about rolling ProofTrail out across your team.
