Nothing overwritten. Every revision retained against the contract.

Everything a subcontractor needs to claim with confidence.

01 Claims and variations in a consistent, professional format every time.

02 Variations captured and tracked, never lost in an email thread.

03 Know exactly what you are owed against the live contract before you submit.

04 A complete record that protects you if a payment claim is ever disputed.

On a paid plan

Run your own work, both directions.

Responding to the head contractor is free forever. Move up to a paid plan and you run and brand your own projects and manage your own subcontractors and suppliers, with the whole commercial workflow working for you, up the chain and down.

Claim up, assess down

Submit your progress claims and variations up in a consistent, SOP-compliant, cent-perfect format, and assess the claims your own subbies send you on exactly the same process.

Variations that keep their margin

Capture every variation at the source with its evidence, so work is never done and never claimed, and you can see whether the changes you take on actually make you money.

Your own cost position

Track budget against committed, forecast and actual on your own packages, so you know where each job stands and what you are really making, not just what you have invoiced.

Procure your own trades

Run your subcontractor and supplier packages from budget to awarded order, and watch the committed cost and the saving land straight on your cost report.

Free when invited

Respond for free. Pay only to run your own.

If a head contractor invites you onto their project, ClaimStack is free, forever. Submit your progress claims and variations, respond to assessments and keep your full record at no cost, with no per-seat fee for being on someone else's job. You only pay when you step up to run your own projects and manage your own supply chain, and even then, every subbie and supplier you invite is free too.

Free to respond, always

Invited onto a job, you claim and respond at no cost. No per-seat fee for being on someone else's project, no subscription just to get paid.

Pay only to run your own

One flat price per seat, the same for every role, and only when you run and brand your own projects. ClaimStack is never priced on your turnover.

Your supply chain, free too

The subbies and suppliers you invite join free, so your whole chain is on the platform without a bill for each of them.

More than a claims tool

Claims, variations, cost and procurement in one place, so the platform grows with you instead of stopping at the claim.

On Payapps, subcontractors pay a subscription to claim, on their published pricing, whether the contract is self-managed or one your builder invited you to. On ClaimStack, anyone invited into a project claims free, with no seat limits, and only the paid subscriber ever carries the cost. See the full comparison →
