Understanding Payment Schedules: What They Mean and What To Do

When a head contractor responds to your payment claim, they do so with a document called a “payment schedule.” Understanding what a payment schedule is, what it must contain, and what it means for your rights is critical to knowing how to proceed after you’ve served a payment claim.

What Is a Payment Schedule?

A payment schedule is the head contractor’s formal response to your payment claim under a Security of Payment Act. It’s the mechanism through which a head contractor either accepts or disputes your payment claim. The payment schedule must be issued within a set timeframe after receiving your payment claim — typically 10–15 business days depending on your state.

What Must a Payment Schedule Include?

Under Security of Payment legislation, a valid payment schedule must:

1. Identify the payment claim it responds to: The schedule must be clearly linked to your specific payment claim
2. State the scheduled amount: This is the amount the head contractor says they’ll pay. If they accept your full claim, the scheduled amount equals your claimed amount. If they dispute part or all of it, the scheduled amount is lower.
3. Identify reasons for withholding: If the scheduled amount is less than the claimed amount, the schedule must state the reasons the respondent is withholding payment. Vague reasons (“quality issues” without specifics) are problematic for the head contractor in adjudication.

What Happens If the Scheduled Amount Is Less Than Your Claim?

If the head contractor’s scheduled amount is less than your payment claim, they’re disputing part or all of your invoice. You have options:

• Accept the reduced amount (if you genuinely agree) and pursue the balance separately
• Apply for adjudication of the disputed balance — this is the recommended course of action

The timeframe to lodge an adjudication application is typically 10 business days from when you receive the payment schedule (QLD has 30 business days). Miss this window and you lose your right to adjudicate on this claim.

What Happens If No Payment Schedule Is Issued?

This is where SOP law is most powerful. If the head contractor fails to issue a payment schedule within the required timeframe:

• The full claimed amount becomes a debt legally owed to you
• The head contractor loses their right to dispute the claim in adjudication
• You can apply for adjudication or go directly to court to enforce the debt

Failure to issue a payment schedule is a significant legal default. Many subcontractors are owed money because head contractors simply don’t respond in time and have essentially forfeited their right to dispute.

Analysing a Payment Schedule — What to Look For

When you receive a payment schedule, review it carefully:

• Are the stated reasons for withholding specific and substantiated?
• Are any alleged defects supported by evidence or inspection reports?
• Are set-off amounts clearly specified and supported by documentation?
• Are liquidated damages claims properly calculated and supported by programme records?
• Is the schedule issued within the required timeframe?

Weak, vague, or unsupported reasons in a payment schedule are excellent grounds for an adjudication challenge.
