See it in action
In construction, disputes don’t go to the side with the best lawyers. They go to the side with the best records. ClarusPM makes sure that side is you — for contractors and subcontractors on site.
If it isn’t written down on the day, it didn’t happen.
The permit was opened. The gang was briefed. The instruction was given at 08:15. The extra was photographed before it was covered up.
That chain exists in ClarusPM. On WhatsApp it does not.
From £9/month · 14-day free trial · No card needed · On a tablet on site and on the office computer · The morning briefing saves and sends when signal returns · Supports your CDM obligations
Every level of contractor faces disputes. The difference between winning and losing is almost always the same — who kept the better record.
From your first job to your biggest contract
Whichever one you are, the risk is the same shape — a missing record, a missed deadline, a claim you cannot defend.
“The customer says they never asked for that extra. I have nothing in writing.”
When the customer disputes it — you have a dated record, a photo, and a voice note from the moment they asked.
“The main contractor keeps changing things and expects us to absorb the cost. They say we agreed verbally.”
When the main contractor says it never happened — you have proof it did.
“The client says we never told them about the delay. We know we did. But we can’t prove when.”
When the client disputes the timeline — the dated, locked site record is in ClarusPM.
“The client is disputing the final account. Our records are across 17 different systems and nobody can find anything.”
When the client disputes month 18 — the full project record is searchable and exportable in hours, not weeks.
Drop in your contract (NEC4, JCT or your own terms) and programme at project setup. ClarusPM reads them with AI and fills in the project details, activities, and planned dates automatically.
One disputed extra can wipe out the margin on a job.
Instructions are given on site, in a hurry, out loud. Weeks later, nobody agrees what was said.
The site record settles it.
The work is done, covered up and invoiced. Then the customer says they never asked for it, and there is no photo and no note.
Site instruction given 01/10/2026 at 08:15 — no record kept. Three weeks later, both sides remember it differently.
Long after the release date has passed. Completion certified, Defects Certificate issued, and still nobody has chased it.
ITP Hold Points unresolved, work continuing anyway. The PM does not know until it is too late.
Not modules you have to learn. Tools that run in the background, building the record you need before you know you need it.

ClarusDocs gives you the RAMS and permits. ClarusPM is where they get briefed, signed, and stored — with every operative’s signature locked to a timestamp.
The notification clock under clause 61.3: eight weeks under the main contract, often far shorter in a subcontract. ClarusPM counts the periods in your contract, not the textbook. ClarusPM was built by NEC4 practitioners: all 21 compensation event types, the clause 61.3 countdown, quotations, early warnings and payment certification are wired in. One unnotified compensation event costs more than years of subscription.
Every user sees exactly what their role needs. The site manager sees the site. The estimator sees the money. The PM sees everything — in real time.
Full access — all projects, all financial data, all modules.
Full accessDashboard, CE management, ITP approvals, RAMS, permits, programme.
Operational leadCommercial module only — CE values, applications, retention, BOQ.
Commercial onlyQA register, drawings, ITP, plant checks, daily reports. No financials.
Technical siteDaily reports, voice notes, RAMS, toolbox talks, plant, operatives.
Site operationsPay for the projects you are running, not per seat. Everyone working on a project — site managers, engineers, the PM — is included. 14-day free trial, no card needed.
The client or main contractor has the system. You have a WhatsApp message and a diary no one can find in month eighteen.
ClarusPM is the subcontractor’s own record of the event — with the timestamp, the photo, and the signed permit attached. Export the signed briefing or permit to PDF and submit it through whichever system the contract uses.
“We built ClarusPM because construction teams deserve a clear view of what is happening on their projects — not a spreadsheet, not a WhatsApp group, not an enterprise platform. One screen. The same picture for everyone. And when you need to prove what happened, the record is already there.”
