More than a third of adjudications end with nothing

Across 1,582 Queensland adjudication decisions made under the current Act, 567 ended with the claimant recovering nothing at all. Not reduced. Nothing.

Under the Act it replaced, that figure was one in seven. It has since held at about one in three, and the last two and a half years look the same as the ten before them.

Counted from 7,601 Queensland adjudication decisions published between November 2004 and June 2026. A nil decision is not always a jurisdictional one; what these numbers measure is the money recovered.

Built for compliance

Three things have to be right before a claim goes out: what is in it, whether it meets the requirements on its face, and when it is served. Paystruct handles each of them in turn.

Build the claim from the contract

The breakdown lives on the contract, so every claim starts from the same items and the same numbering. You enter progress; the arithmetic follows.

Quantities and units on every line, not percentages alone
Previously claimed, this claim and claimed to date always reconcile
Variations, adjustments and retention carried through automatically
Your item numbering, headings and sub-items kept intact

Check it against the requirements

Before anything is served, Paystruct works through what the legislation asks of a payment claim on its face, and shows the section it is working from.

Reference dates worked out from the contract, and checked against earlier claims
Timing measured in business days, on the calendar for your State
Descriptions tested for whether they identify the work
Anything it cannot decide is put to you rather than assumed

Know where you stand on dates

Once a claim is served the clock is running. The calendar shows what has been served, what is owed back, and how long is left to respond.

Public holidays and the December shutdown excluded

Set the contract up once

The contract holds the parties, the dates, the security and the breakdown. After that a claim is a period and a set of figures, not a document rebuilt from scratch.

Create an account

01

Set up the contract

Parties, State, reference dates, retention and the schedule of works. Upload the contract and have the terms read out of it, or enter them yourself.

02

Build the claim

Enter progress against each item as a quantity, a percentage or a dollar figure. Variations, adjustments and retention come through from the contract record.

03

Check it before it goes

Paystruct works through the requirements it can check, and asks you about the ones that depend on facts only you have.

04

Serve it and record it

Export the claim pack, serve it the way your contract allows, and record the date, the method and the proof against the claim.

Built for claimants

Whoever is making the claim, up the chain or down it.

For subcontractors

Claim what you are owed, on time, every month.

For head contractors

Claims up the chain, obligations down the chain.

Common questions

Which States does Paystruct cover?

Queensland, New South Wales and Victoria. Each has its own rules, and they are not the same: Queensland works on reference dates, New South Wales removed them in the 2018 amendments, and Victoria moved to a similar model in the 2026 reforms. A contract is set up under one State and the dates, wording and section references follow it.

Does Paystruct tell me whether my claim is valid?

No, and you should be sceptical of anything that says it does. Whether a claim is valid turns on your contract, the facts and the legislation. What Paystruct does is work through the requirements that can be checked from your own data, put the ones that depend on your facts in front of you before anything is served, and keep the record of what went out and when.

Is this legal advice?

No. Paystruct is software. It is not a law firm and does not act for you. For a contested claim, a final claim, a terminated contract or an adjudication, get a lawyer.

Do I have to move everything across to start?

No. Set up one contract and make one claim. If the job is already running, upload the claims you have already served and Paystruct builds the breakdown and the history from them, so your numbering carries on where it left off.

What counts as a contract?

One head contract or subcontract, with its own parties, dates, security, breakdown and claim history. Separable portions of the same contract are not counted separately.

What does it cost?

Your first contract is free. Every contract after that is $49 per month, excluding GST, with every feature included and no fee per claim. See pricing.

Can I still use my own claim format?

The claim pack is built from your contract breakdown, so it carries your item numbering, your descriptions and your attachments. The cover letter, the summary and the supporting statement are all editable before anything is served.

What happens to my records if I stop paying?

They stay yours. Claim packs and the record behind them export as PDFs at any time, so the history of what you served and when does not sit only inside Paystruct.
