Progress Payments and Paying Ahead

A builder may ask you to pay quickly to keep trades moving or secure materials. Most homeowners want to cooperate. The danger is allowing cooperation to turn into payment materially ahead of contractual progress. In South Australia, the Building Work Contractors Act 1995 (SA) generally limits builders to genuine progress payments for work actually performed, apart from any authorised advance payment. A separate guide explains how progress payments work generally; this guide focuses on the specific risks of paying ahead of earned progress and how to protect your position when a claim arrives.

The payment schedule is a risk-allocation mechanism

Progress payments are intended to link money to defined construction milestones. The stage name on an invoice is not, by itself, proof that the contractual milestone has been achieved.

Paying ahead changes your commercial position

If you pay for work before it is contractually due, you may lose an important practical protection. If the builder later experiences financial difficulty or a dispute arises, money already paid can be difficult to recover.

Your lender’s approval is not a legal opinion

A bank valuation or progress inspection primarily serves the lender’s purposes. It should not automatically be treated as confirmation that every contractual precondition to payment has been satisfied.

Defects and variations require judgment

A minor defect does not necessarily mean a whole progress stage is unpaid, while substantial incomplete work may mean the stage has not been reached. Keep the original contract sum separate from approved variations, provisional-sum and prime-cost adjustments and credits so each invoice can be reconciled against a running project ledger.

Do not create a default while investigating

Progress-payment clauses often contain strict payment periods and consequences for non-payment. If you dispute a claim, act promptly, communicate in writing and obtain advice rather than simply ignoring the invoice.

Questions to ask before signing

What milestone is being claimed and has it actually been achieved? What documents are required? Are variations correctly included? Is the amount consistent with the payment schedule? What is the deadline to respond or pay?

The key lesson

Pay what is properly due, when it is properly due. That approach is fair to the builder and preserves the homeowner’s contractual protection.

Before You Sign

This guide provides general educational information for South Australian homeowners. It is not personalised legal advice. The effect of any issue depends on the wording of your own contract, schedules, Special Conditions, plans, specifications and the facts of the project. A good builder and a well-understood contract should work together. Before committing to one of the largest financial transactions you may ever undertake, consider having the actual contract reviewed so you understand the obligations, notice requirements and consequences before they are tested on site.
