The $3.2 Billion Problem

Research consistently shows that Australian subcontractors lose over $3.2 billion in unpaid invoices every year. The Security of Payment Act exists specifically to fix this — and yet more than 90% of subcontractors who are owed money never use it.

Here are the five most common reasons — and how to fix each one.

Reason 1: “I don’t know how the SOP Act works”

Most subcontractors have never received any formal education on their legal rights under the Security of Payment Act. The construction industry’s focus is on the tools and the work — legal training rarely features.

The fix: You don’t need to become a legal expert. PayClaim’s AI analyses your entitlement and explains exactly what you’re owed and why. You just need to know the Act exists — and that you can use it.

Reason 2: “Lawyers are too expensive”

This is the biggest barrier. Traditional SOP Act claims handled by solicitors cost $5,000–$15,000 — sometimes more for complex matters. For a $25,000 invoice, that’s 20–60% of the amount you’re trying to recover.

The fix: PayClaim automates the entire process for $69 per claim. The legal framework is defined and consistent — AI can generate compliant documents faster and cheaper than any law firm.

Reason 3: “I don’t want to damage the relationship”

Subcontractors often worry that asserting their legal rights will cost them future work. This is understandable — but misguided. A client who owes you money and won’t pay it has already demonstrated their attitude toward your relationship.

The fix: Payment claims are professional legal documents, not aggressive threats. Most head contractors simply pay when they receive a formal SOP Act claim — because they know exactly what happens if they don’t.

Reason 4: “I’m not sure if I qualify”

The language of the Acts is formal and can be confusing. Subcontractors often wonder whether their particular work qualifies, whether their contract is covered, or whether they’ve missed a deadline.

The fix: PayClaim’s AI analyses your specific situation against the Act and gives you a clear entitlement assessment with a confidence percentage. You’ll know in minutes whether you can claim.

Reason 5: “I’ve already written it off”

After months of chasing, many subcontractors simply stop pursuing unpaid invoices. They absorb the loss and move on.

The fix: Check your deadlines — if the invoice is recent, you almost certainly still have time to claim. PayClaim can assess your entitlement in minutes, even for invoices that are several months old.

The Bottom Line

The Security of Payment Act is one of the most powerful commercial tools available to Australian subcontractors — and it’s almost never used. PayClaim exists to change that.
