Not getting paid for all your variations
Delays and disruption costing YOU money
Valuations always getting cut back
Cashflow constantly tight
Retentions dragging on
Feeling like you’re always “behind” on paperwork
Variations — How to make sure you get paid for every change
Delays & Disruption — How to protect your time and costs
Monthly Valuations — How to get paid in full, on time, every time
Delay and disruption used to kill our margins in dry lining - standdowns, re-sequencing, late access.
Subcontractor OS gave us a clear playbook: notify early, evidence everything, and submit clean delay analyses with commercial back-up.
We’re now turning lost days into agreed extensions of time and recoverable costs instead of disputes, and our cash flow is far steadier.

McConville Drylining & Plastering
Subcontractor OS has changed how we run the commercial side of our civils jobs.
I learned the hard way what a lack of structure costs; now we work proactively—notice first, tight evidence, clean submissions.
Issues that once drifted toward disputes are resolved sooner, variations are agreed faster, and our monthly cash flow is far more predictable.
It’s the commercial discipline we were missing.

Roadform
Subcontractor OS has been a masterclass in change control.
It’s shown us what ‘good’ looks like—early notices, solid evidence, and clean submissions—and we’ve adopted the same checklists and language internally.
The result is less friction with subcontractors, faster approvals, clarity for all parties and far more predictable cost and time outcomes.
I’m learning every week, and as a result we are delivering projects on time with things running smoother.

P. Loughran Construction
Subcontractor OS gave me a disciplined system that makes the commercial side predictable.
I’m now submitting variations and delay & disruption notices on time, fully evidenced and consistent.
The Subcontractor OS GPT is the real game-changer.
It drafts notices, checklists, and trackers in minutes so nothing slips.
Approvals are faster, disputes are rarer, and I’ve got the confidence that every claim stands up.

Coleman Civils and Construction
Subcontractor OS has transformed how we handle variations in fit-out.
We’re now catching changes we used to miss, submitting airtight back-up, and getting paid faster.
It’s made a clear difference to our bottom line.
