Why did a claim you know is right come back lower? Usually because the person verifying it could not match a line to the site, the contract or the paperwork. Here is what gets checked, what to attach and what happens when the number is cut.
Quick Answer
Progress claim verification is the head contractor's or quantity surveyor's check that the work, materials and variations in a subcontractor's progress claim match what is on site and in the contract. To pass first time: itemise the claim to the contract schedule; attach dated photos, dockets and signed variation instructions; and expect any cut to come back as a payment schedule with reasons. If the wait strains cash, invoice finance is one way to bridge it.
Also called: payment claim verification, progress payment assessment, claim certification. "Payment claim" is the security of payment term; "certification" is often used when a quantity surveyor or superintendent signs off.
What is progress claim verification, and who does it?
Progress claim verification is the check a head contractor runs on a subcontractor's claim before agreeing what to pay. It is usually done by the head contractor's project manager, a quantity surveyor or a superintendent named in the contract, and it is measured against the subcontract, not against what the trade feels the job is worth.
A progress claim from a subcontractor is tested against three things: the work on site, the schedule of values or price breakdown in the subcontract, and the paperwork that comes with it. This is the construction meaning of the term. When a lender's quantity surveyor certifies work before a construction loan drawdown is released, that is a different check with a different purpose, and our progress claims and drawdowns guide covers it.
In practice, verification is the gate before the cash. Nothing is paid until the person checking the claim agrees the amount, or puts a lower figure and the reasons for it in writing. Knowing what they test, line by line, is how a claim gets through the gate on the first pass.
What does a head contractor or quantity surveyor check on site?
A head contractor or quantity surveyor checks measured quantities, the percentage complete against the schedule of values, materials on site, variations and defects. Each line of your claim is either matched to something they can see, count or read in the contract, or it is marked down.
| Item checked | How it is usually checked | Evidence to attach |
|---|---|---|
| Percentage complete | Site walk against the schedule of values, line by line | A claim itemised to the same lines as the contract schedule, showing previous, this period and cumulative amounts |
| Quantities installed | Measured on site or taken off marked-up drawings | Marked-up drawings, measurement sheets and dated photos |
| Materials on site, not yet fixed | Sighted on site; some subcontracts only pay once materials are fixed in place | Delivery dockets, supplier invoices and photos showing location and quantity, if the contract allows the claim |
| Variations | Matched to a written instruction and an agreed or assessed price | The signed variation instruction, the quote or rates used and the date of the direction |
| Quality and defects | Inspection against the drawings, specification and any hold points | Inspection and test records and hold point sign-offs |
| Claim period and form | Checked against the claim dates and content the contract requires | A claim dated in the right period with the contract reference, and a tax invoice where the contract asks for one |
| Workers, insurance and your own subcontractors | Checked for any statements the contract or state law requires | Signed payment statements and current insurance certificates |
From the head contractor's side the test is simple: can this number be defended to the client or superintendent above them? A line that cannot be matched to the site or the contract is the line that gets cut. So claim what the site shows, not what the program says should be finished by now. A trade that claims ahead of the site once tends to have every later claim measured more closely.
What evidence should you attach so the claim can be verified?
Attach whatever lets the checker tick each line without having to call you: an itemised claim, dated photos, delivery dockets, signed variation instructions and any statements your contract or state law requires. The evidence travels with the claim. If it arrives a week later, the checker waits, and so does your money.
- An itemised claim. Each line mirrors the contract schedule, with the amount claimed to date, this period and the cumulative total.
- Dated photos. Wide shots for location and close shots for detail, labelled to the claim lines they support.
- Delivery dockets and supplier invoices. For materials claimed but not yet fixed in place, where the subcontract allows that claim.
- Signed variation instructions. One per variation, with the agreed price or the rates you used.
- Statements and certificates. Worker and subcontractor payment statements and current insurance certificates, where your contract or state law asks for them.
What you attach
- Claim lines that match the contract schedule
- Dated photos tied to each line
- Dockets for materials on site
- A signed instruction for every variation
- Current insurance and payment statements
What the checker marks down
- A lump sum with no breakdown
- Percentages ahead of what is on site
- Variations claimed on a verbal okay
- Materials with no proof of delivery
- A claim lodged outside the claim period
What a claim must contain to be a valid payment claim is a separate question that varies by state, and our drawdowns guide covers what has to be on a progress claim. If the wait between claims is what is hurting, check eligibility for claim-based funding before the next one goes in.
How are variations checked when you claim them?
Variations are checked against a written instruction and an agreed or assessed price, so a variation claimed on a verbal direction is the line most likely to be held back. A variation without an instruction is a dispute in waiting.
Where the subcontract sets out how variations are directed and priced, the checker follows that clause to the letter. If a site manager asked for extra work and nobody signed anything, expect the checker to ask for the instruction before assessing it, and expect a lower figure, or nothing, if there is none. Get the direction in writing on the day, even as a short email that names the work, the location and the rate.
Claim each variation on its own line rather than folding it into a base contract item. A separate line can be approved while a disputed one is argued, and it stops one contested variation from holding up the whole claim.
In Victoria, the Building and Plumbing Commission says security of payment amendments in force from 15 April 2026 removed the separate concepts of claimable variations and excluded amounts. The same amendments mean a notice-based time bar has no effect if an adjudicator, court, arbitrator or appointed expert finds it unfair, which matters when a variation notice goes in late. That changes what can sit in a payment claim there; it does not remove the need to prove the variation was directed. How the Victorian changes play out for a trade's debtor book is covered in invoice finance in Melbourne, and whether a disputed variation can be funded is answered in our progress claim finance guide.
Why does the verified amount come in lower than your claim?
The verified amount usually comes in lower because a percentage was claimed ahead of the site, a variation had no instruction, defects were found, a back charge was applied or documents were missing. Retention is deducted on top, so the amount paid is lower than the amount verified even when nothing is in dispute.
- Overclaimed percentage. The line is claimed further along than the site walk shows.
- Unapproved variations. No signed instruction, or a price nobody agreed.
- Defects and incomplete work. Work that fails inspection is valued at less, or at nothing, until it is fixed.
- Back charges and set-offs. Clean-up, damage or delay costs the head contractor says you owe, deducted from the claim.
- Missing documents. No dockets, no photos, no statements the contract requires.
- Wrong claim period. A claim lodged early, late or for work outside the period.
Retention is held under the contract, typically a percentage of each claim up to a cap, and is usually released in stages such as practical completion and the end of the defects period. How retention is treated when a claim is funded is covered in our progress claim finance guide.
Where this commonly lands: the first claim to a new head contractor comes back lower, the trade learns what that checker wants, and the next claim passes. Asking for the head contractor's claim format and evidence list before you lodge the first claim shortens that learning curve.
What happens after verification if you get less than you claimed?
If the head contractor will pay less than you claimed, security of payment laws require a payment schedule that states the amount it will pay and its reasons, within a set number of business days. A schedule must give its reasons. A lower number with no explanation does not meet the test.
In New South Wales, the NSW Government security of payment guidance (last updated 28 September 2026, read 9 October 2026) says a payment schedule must be provided within 10 business days after the claim, that a schedule is only valid if it is provided within the set periods, and that only a claimant can start adjudication. In Victoria, the Building and Plumbing Commission's guidance is that a respondent must either pay the full amount by the due date or provide a payment schedule within 10 business days.
Other states set their own periods, and our drawdowns guide sets out the security of payment deadlines by state. What to do when the schedule is lower than your claim is answered in the progress claim finance guide. Whether to dispute a payment schedule or apply for adjudication is a question for your solicitor.
The reasons in a payment schedule are often the most useful thing a trade gets back from verification. They name the exact lines, and the exact evidence, to fix before the next claim goes in.
How do trades cover wages and materials while a claim is being verified?
Trades usually cover wages and materials during verification from their own cash buffer, a line of credit or a facility that advances against claims, and which one fits depends on how regular the claims are and how reliably the head contractor pays. The full comparison, including what funders check and why many restrict progress claims, sits in our progress claim finance guide.
If your claims are regular and your head contractors pay on time, invoice finance or a business line of credit may fit, and the invoice finance guide explains how advances against unpaid invoices work.

More construction reading sits in the Construction Hub, the construction loan pack and the Business Owners Hub.
Progress claim verification is a line-by-line match of your claim against the site, the subcontract and the paperwork. Claims that pass first time are itemised to the contract schedule, carry their own evidence and hold a signed instruction for every variation. When a claim comes back lower, the payment schedule's reasons tell you exactly what to fix before the next one.
Key takeaway: claim what the site shows and send the evidence with the claim, because verification is the gate before the cash.Frequently Asked Questions
A subcontractor progress claim is verified by the head contractor, usually through its project manager, a quantity surveyor or a superintendent named in the contract. They check the claim against the site and the subcontract schedule before agreeing what to pay. Our progress claim glossary entry covers the term itself.
Contractors making progress claims in Australia typically need an itemised claim matched to the contract schedule, dated photos, delivery dockets for materials, signed variation instructions and any payment statements or insurance certificates the contract or state law asks for. Exact requirements vary by contract and by state. Our progress claims and drawdowns guide covers what has to be on the claim itself, and a tax invoice may be needed as well.
Project progress claims are checked against the contract by matching each claimed line to the schedule of values, the percentage complete on site and any approved variations. Lines that cannot be matched are reduced or held until the evidence arrives. On larger jobs a quantity surveyor usually does this check for the head contractor.
A head contractor that wants to pay less than your progress claim generally has to give a payment schedule with its reasons under security of payment laws, within a set number of business days. In New South Wales, a payment schedule is only valid if it is provided within the set periods. As the subcontractor, what you can do next is covered in our progress claim finance guide, and whether to dispute the schedule is a question for your solicitor.
Whether you have to claim variations separately in a progress claim depends on your subcontract, but showing each variation as its own line, with its signed instruction attached, makes it far easier to verify. Bundled variations are often held back until the checker can match them to an instruction. Our insight on how lenders read progress claims on a unit build shows the same discipline at work on funded projects.
