PROJECTS

Build a compliant payment claim, step by step.

Sopal's Payment Claim Builder guides you through every element the SOP legislation requires — claimant details, reference date, claimed amount, work identification, and any mandatory statements — then produces a claim ready to serve.

Jurisdiction-aware

The builder adapts its prompts and required fields to the Act that governs your contract — BIF Act (QLD), NSW, VIC or SA — so nothing required by your jurisdiction gets overlooked.

Guided, not guesswork

Each step explains what the legislation requires and why. If you are unfamiliar with concepts like reference dates or progress claims, the builder walks you through them in plain language.

Export and serve

When the claim is complete, export a clean, formatted document ready to serve on the respondent. Keep a copy in Sopal for your records and for any downstream adjudication work.

HOW IT WORKS

A structured build flow for every claim element

Payment claims under Australian SOP legislation must satisfy specific formal requirements. Missing or incorrect elements can affect whether the claim is a valid payment claim under the Act — which in turn affects your adjudication rights. Sopal keeps you on track.

  • Claimant and respondent identification
  • Reference date selection with due-date preview
  • Claimed amount and supporting schedule of works
  • Identification of the construction work or related goods and services
  • Required endorsements and statements where the Act demands them
  • Final review before export

VALIDITY CHECKLIST

Know your claim is complete before you serve it

The builder runs a completeness check before you export, flagging anything that looks incomplete or inconsistent. Catch issues at the drafting stage — not after service when it is too late to correct them.

  • Confirms a valid reference date has been selected
  • Checks that the work or related goods and services are described
  • Flags missing mandatory endorsements required by your jurisdiction
  • Verifies the claimed amount is recorded
  • Alerts you if the claimant or respondent fields are incomplete

THE LEGISLATION

What makes a payment claim valid under the SOP Acts

Security of payment legislation in Australia creates a statutory right to progress payments for people who carry out construction work or supply related goods and services. To trigger that right, a claimant must serve a valid payment claim on the respondent. The formal requirements for a valid claim differ in their details across jurisdictions, but share a common structure.

What the claim must identify

Across all four jurisdictions supported by Sopal — Queensland, New South Wales, Victoria and South Australia — a payment claim must identify the construction work or related goods and services to which the claim relates. This is a threshold requirement. If the respondent and any subsequent adjudicator cannot understand what the claim is for, the claim may be found to be invalid or may be given limited weight.

The standard does not require forensic precision, but the description must be sufficient to allow the respondent to understand the scope of work being claimed. In practice this means referencing the relevant contract, the period of work, the portion of the project, or any other identifying information that makes the scope clear. Sopal's builder prompts you to provide this information in a structured way.

Reference dates

A claimant can only serve a payment claim on or after a reference date. Reference dates are either set by the contract (for example, the last day of each month, or dates tied to progress milestones) or, where the contract does not provide for them, by the relevant Act. The rules differ by jurisdiction and have been amended over time — always confirm the current position under the Act that applies to your contract.

Getting the reference date right matters because a claim served before a reference date arises may not be a valid payment claim. Sopal prompts you to identify and record the reference date so it is documented as part of the claim.

Claimed amount

The claim must state the amount being claimed. In practice this is supported by a breakdown — a schedule of the work done, the rates or lump sums applying, and any deductions or adjustments. A well-supported claimed amount makes it easier for the respondent to provide a meaningful payment schedule and gives an adjudicator a clear basis for assessment. The builder provides a structured schedule so the amounts are set out clearly.

Mandatory endorsements and statements

Some jurisdictions require the document to include a specific statement, notice or endorsement to the effect that it is made under the relevant SOP legislation. The requirement, its exact wording, and the consequences of omission differ by state and have been subject to legislative amendment and judicial consideration. Sopal's builder includes the relevant prompt for the jurisdiction you select and flags this step during the validity check.

Service

A payment claim must be served on the respondent. Service requirements — who can be served, how service must be effected, and what constitutes valid service — are set out in the relevant Act and may also be addressed by the contract. This is a critical step: the timing of the respondent's obligation to provide a payment schedule (and therefore the timing of any adjudication application) runs from service of the payment claim. Sopal exports a clean claim document ready to serve; the method and timing of service is your responsibility and, if in doubt, should be confirmed with a lawyer.

Jurisdiction comparison

The table below summarises some of the key structural features across the four supported Acts. Timeframes and procedural details are indicative only — always verify against the current Act for your jurisdiction.

WHO IT IS FOR

Subcontractors

If you are claiming payment from a head contractor or principal, the builder guides you through each required element so you do not miss anything that could be used to challenge the claim's validity. Protect your adjudication rights from the outset.

Head contractors

Head contractors claiming against principals or developers face the same formal requirements. Use the builder to ensure your progress claims are properly structured and documented, especially on large or complex projects with multiple claim periods.

Contract administrators and quantity surveyors

If you prepare payment claims on behalf of claimants, the builder gives you a repeatable, structured process that produces consistent, well-documented claims across all the projects you manage — and across multiple jurisdictions.

Developers and principals

Understanding what a valid payment claim looks like helps you assess incoming claims from contractors and identify whether they meet the statutory requirements before the payment schedule deadline arrives.

WORKS WITH

Part of the Sopal Projects suite

The Payment Claim Builder is one of several tools in Sopal Projects designed to support the full payment-claim lifecycle. Once a claim is built and served, the same project in Sopal holds the record of the claim for any downstream steps.

  • Payment Claim Review — if you have received a payment claim and need to assess it before the payment schedule deadline, use the Payment Claim Review tool to work through the claim systematically.
  • Payment Schedule Builder — draft a payment schedule in response to a payment claim, with the same guided, jurisdiction-aware approach. See Payment Schedule Builder.
  • Payment Schedule Review — assess a schedule you have received from a respondent. See Payment Schedule Review.
  • Due Date Calculator — calculate the key dates running from service of a payment claim: when a payment schedule is due, when the scheduled amount becomes payable, and when an adjudication application can be made. See Due Date Calculator.
  • Interest Calculator — calculate statutory interest on overdue amounts under the relevant Act. See Interest Calculator.

All tools are available in Sopal Projects and in Sopal Plus (which also includes the Sopal Research database of 7,300+ Queensland adjudication decisions and AI-driven case-law research).

FAQ

Questions, answered.

Does the builder tell me whether I have a valid payment claim?

The builder guides you through the structural elements the legislation requires and flags incomplete fields before you export. It does not give you a legal opinion on whether your claim is valid — that depends on your specific contract, the facts of your situation, and the current state of the law. If you are unsure whether a claim you are about to serve is valid, speak with a construction lawyer. Sopal is general information, not legal advice.

Which jurisdictions does the builder support?

The builder supports Queensland (Building Industry Fairness (Security of Payment) Act 2017), New South Wales (Building and Construction Industry Security of Payment Act 1999), Victoria (Building and Construction Industry Security of Payment Act 2002), and South Australia (Building and Construction Industry Security of Payment Act 2009). The prompts and required fields adapt to the jurisdiction you select.

What is a reference date and how does the builder help me with it?

A reference date is the date on or after which you are entitled to serve a payment claim under the Act. Reference dates are typically set by the contract (for example, the last day of each month, or dates linked to milestones). Where the contract does not provide for them, the Act sets default dates. Serving a claim before a reference date has arisen can affect the claim's validity. The builder prompts you to identify and record the reference date applicable to your claim. Because the rules differ by jurisdiction and have been subject to amendment and judicial consideration, you should confirm the position under the Act that applies to your contract.

Do I need to include a statement that the document is a payment claim under the Act?

Yes, in most jurisdictions the legislation requires the claim to include a statement to the effect that it is made under the relevant Act. The exact wording required, and the consequences of omitting it, differ by jurisdiction and have been the subject of legislative amendment. Sopal's builder includes the relevant prompt for the jurisdiction you select and flags this element in the pre-export checklist. Confirm the current requirement under the Act applicable to your contract before serving.

How detailed does my description of the work need to be?

The legislation requires the claim to identify the construction work or related goods and services to which it relates. Courts and adjudicators have generally held that the description must be sufficient to allow the respondent to understand what is being claimed — it does not need to be exhaustive, but it must be meaningful. In practice, referencing the contract, the relevant period, and the scope or portion of work is a sensible starting point. The builder prompts you to provide this information in a structured way.

Can I use the builder for subcontract claims as well as head-contract claims?

Yes. The builder is designed for any party in the contractual chain who has the right to make a payment claim under the relevant Act — including subcontractors, sub-subcontractors, suppliers, and head contractors. The key question is whether your contract is a construction contract for construction work or related goods and services under the Act. If you are unsure whether the Act applies to your contract, seek legal advice.

What format does the exported claim take?

The builder exports a formatted document that sets out the claim elements in a clear, structured layout suitable for service on the respondent. You retain a copy in Sopal linked to the relevant project for your records. The specific format of the export can be reviewed when you complete the build flow.

Is the Payment Claim Builder the same as the Payment Claim Review tool?

No. The Payment Claim Builder is for claimants — it helps you draft and export a payment claim you intend to serve. The Payment Claim Review tool is for respondents (or claimants checking a claim they have received) — it helps you work through an incoming payment claim to assess it against the statutory requirements before the payment schedule deadline. Both tools are included in Sopal Projects.

Does Sopal Projects include any research tools to help me understand the law around my claim?

Sopal Projects includes the claim and schedule builders, reviewers, and calculators. If you also need access to the adjudication decision database (7,300+ Queensland decisions) and AI-driven case-law research across NSW, QLD and VIC, you need Sopal Research or Sopal Plus, which bundles both products. Plus is often the most cost-effective option if you need both.

GENERAL INFORMATION
