Solutions/Head contractors

You carry the risk. Demand the visibility.

You’re accountable for every claim, variation, commitment and final account. ClaimStack brings the whole commercial chain into one connected system, so you always know where the margin stands.

The commercial OS for head contractors

Standardise commercial. Centralise control. Protect margin.

ClaimStack connects procurement, variations, claims, forecasting and reporting into one live commercial record, so you always know what’s committed, what’s at risk, and where the margin is going. No chasing. No spreadsheets. No surprises at month-end.

Standardise commercial across every project

Your best commercial process should not depend on who is running the job. Company-wide templates and one disciplined workflow mean every project runs claims, variations and cost reports the same way, so you get a portfolio you can compare and hold to a standard, not a dozen jobs each run their own way.

Capture, connect and report it.

In most businesses the project team is the glue between systems, copying a number from the claim to the register to the report and hoping nothing drifts. ClaimStack captures each commercial event once and keeps every view reading the same record, so that whole job disappears. Nothing is re-keyed, nothing is lost, and the people you pay to manage the numbers actually get to manage them.

Your forecast, backed by live truth

A forecast that is weeks out of date tells you where the margin went, not where it is going. Because the position moves as commitments, variations and claims land, exposure shows up while there is still time to act on it, to renegotiate, rescope or pull a job back, instead of explaining the overrun at final account.

Final account without the headache

When every commercial event was captured as it happened, closing a job out is reading the record, not rebuilding it from a year of emails and spreadsheets. The final account reconciles to the cent, the trail is already there if it is ever questioned, and the weeks a team usually loses to reconstruction go back into the next job.

You’re accountable for everything. But you can’t see everything.

01 Commercial detail is buried in inboxes and spreadsheets no one can reconcile.
02 Rework and missed variations cost margin you can’t afford to lose.
03 Your project team chases paperwork instead of managing the numbers.
04 No live picture of which projects are on track and which are slipping.
Real time, not month-end

A finger on the pulse of every project.

Commercial work does not stand still, and your view of it should not either. Every claim, variation and commitment feeds straight back into the live position, a continuous loop, so you see the change as it happens, watch the cash position move, and manage risk across the whole portfolio in real time. The issues surface while there is still time to fix them, not at month-end when the margin is already gone.

Changes in real time

A variation submitted, a claim assessed, a commitment raised, each one moves the position the moment it happens, so what you see is where the job actually is today, not at the last month-end.

Cash position, live

Watch the cash moving in and out across each project and the whole portfolio, so you know what is due, what is coming, and where a squeeze is building before it bites.

Portfolio risk at a glance

See which projects are ahead and which are slipping across the portfolio, ranked by exposure, so your attention goes where the margin is most at risk.

Time to act

Because the position updates continuously, an overrun or a slow-paying job shows up early, while there is still room to do something about it, not weeks after the fact.

The key win

More time delivering, less time updating systems.

The real cost of running commercial across a dozen tools is not the licences, it is the hours your team spends keeping them all in step. A number typed into a spreadsheet, then the claim, then the cost report, is three chances to drift and three jobs nobody wanted. ClaimStack captures each commercial event once and keeps every view connected, so the register, forecast, claim and cost report all move from the one entry. Your team stops maintaining systems and gets back to delivering the project.

Captured onceEntered a single time and read everywhere, no re-keying the same number into four places.
No duplicationOne connected system, not eight tools and a folder of spreadsheets to reconcile against each other.
Less adminThe hours spent updating systems and chasing paperwork go back into managing the job.

The whole workflow

The whole commercial chain, one record.

You run the job, so you carry every part of the commercial chain. On ClaimStack each workflow feeds the same live record, so a number entered once is trusted everywhere, from the first tender to the final account.

Procurement

Run each package from budget to awarded subcontract, level the bids like-for-like, and watch the committed cost and the saving post straight to the cost report.

Variations

Capture every variation against the contract clause that gives rise to it, assess it line by line, and approve it properly through the workflow, so the change is agreed the right way, tracked as an immutable record, and reflected in the cost report.

Payment claims

Claim up to the principal and assess your subcontractors down, cent-perfect and compliant with Security of Payments, with deadlines tracked and cashflow updated from every claim.

Cost reporting

Budget, committed, forecast and actual on one line, current whenever you open it, with the contract works and the variations measured apart so you see the real margin.

Forecasting

See where the cost to complete is heading, with variations in flight and known exposure in view, so you catch a problem while you can still act on it, not weeks after the fact.

The Financial Hub

Cost and revenue, one financial picture.

Every workflow, procurement, invoices, claims and variations, feeds the Financial Hub, where the whole money position of the business lives. Budgets and the cost landing against them on one side, certified revenue and what is still to come on the other. A builder does not wait on the accountant to stitch it together, the cost to complete, the revenue position and the margin on every project sit in one place, live, whenever you look.

CostBudgets, committed and actual, fed straight from procurement, subcontracts and invoices.

Frequently asked

How is ClaimStack different from spreadsheets?

Spreadsheets make the project team the integration layer, copying numbers between claim, register, forecast and report, and hoping nothing drifts. ClaimStack captures each commercial event once and keeps every downstream view connected automatically. No re-keying, no lost evidence at final account.

Can subcontractors and consultants use it too?

Yes. ClaimStack is built for the whole project team. Subcontractors submit claims in a consistent format, assessed against the live contract position. Every action is linked to the contract and project it belongs to, so the head contractor keeps a complete, traceable record.

Does it work with our accounting system and ERP?

Approved claims, invoices and commitments flow to Xero, MYOB and your ERP, no double entry. Documents connect from Procore, Aconex and email, so a commercial event carries its evidence.

Is it compliant with Security of Payments?

Every payment schedule carries adjustments, reasons and email records with a full audit trail, and automated reminders keep you ahead of statutory deadlines, so you’re protected if a claim is ever adjudicated.
