A Progress Claim Is Being Disputed

The scenario

On a staged contract you have lodged a progress claim for work completed to date. The customer responds with a payment schedule or a reply that disputes part of it — they say a milestone is not finished, the measured quantities are wrong, or variations were not approved. Crucially, they are withholding the entire claimed amount, not just the part in dispute, which puts pressure on your cash flow at exactly the wrong point in the job.

This is one of the most common flashpoints in commercial trading, and it is also one where the contract — and in some industries, security-of-payment legislation — sets out a specific process you ignore at your peril.

What's really going on

Progress-claim disputes usually mix a genuine measurement question with a negotiating tactic. The genuine part might be a milestone that is 90 per cent rather than 100 per cent complete, or a variation done on a verbal nod that was never papered. The tactical part is withholding the whole claim to gain leverage over the disputed slice — a classic pressure play that relies on you needing the cash.

In construction and related industries, many jurisdictions have security-of-payment regimes with strict timeframes for issuing payment claims and schedules. Missing a step can forfeit rights for either side. So a progress-claim dispute is rarely just a commercial disagreement — it often sits on top of a contractual and sometimes statutory framework that rewards whoever follows the process precisely.

Your options

• Ring-fence the undisputed amount. Press for immediate payment of the portion that is not genuinely in dispute, so the argument narrows to the real gap.
• Substantiate the claimed stage. Produce site records, photos, signed dockets, measurements and variation approvals that evidence the work claimed.
• Negotiate the variance. Where the gap is a measurement or scope question, a documented compromise on that slice can unlock the rest.
• Use the contractual or statutory process. Issue or respond to payment schedules within the required timeframes; in some industries adjudication is a fast, binding route.
• Take specialist advice. Security-of-payment timeframes are unforgiving, so get advice before a deadline passes.

Recommended approach

Move first to separate the undisputed money from the disputed money. There is rarely a good reason for the customer to hold a payment in full when only part is genuinely contested, and saying so plainly — backed by your records — often releases the bulk quickly. For the contested portion, lead with evidence rather than argument: signed dockets, dated photographs, approved variations and measured quantities settle most progress disputes faster than correspondence does.

If your work falls under a security-of-payment regime, treat the timeframes as the priority — they can determine the outcome regardless of the merits. Document everything contemporaneously on future claims so the next dispute is shorter. For the wider picture on commercial recovery and evidence, the Academy lesson library is a useful reference, and where a balance remains unpaid you can refer the debt with the claim history attached.

What to avoid

Do not let the customer treat a part-dispute as a reason to hold the whole claim — challenge that immediately, because conceding it teaches them to do it every time. Avoid relying on verbal variation approvals; if it is not in writing it is hard to prove, so paper variations before you do the work. Never assume the merits will save you under a security-of-payment regime — missing a statutory deadline can be fatal regardless of who is right. This is general guidance, not legal advice; because progress-claim law is technical and varies by jurisdiction, obtain specialist advice on your contract and your timeframes.
