When the job is costing more than you’ll be paid

Do not let the job make the decision for you

A job can look fine at tender stage and still turn sour once labour, materials, plant hire and rework start stacking up. The danger is not just a thin margin. It is finishing a project that drains cash you do not have, while hoping the final claim somehow fixes the loss.

The fix is to slow down before the numbers force the decision for you. If you stop without a plan, you can lose leverage with the builder or client, miss chances to recover extra costs, and leave unfinished work that becomes harder to explain or charge for later in writing.

Work out the real cost to complete

Start with a real cost-to-complete figure, not a hopeful one. Add the labour still needed, materials not yet ordered, subcontractor bills, plant costs, supervision time, defects you still have to fix and the cash timing between now and final payment. That is the number that matters to you in practice.

If that figure shows a loss, do not guess your way through it. Check what has already been committed, what can still be changed, and whether the remaining scope can be re-priced or narrowed. Business.gov.au says a quote should include itemised costs, variations and payment terms, which is why the paperwork matters.

Look for variations you can still claim

Variations are the first place to look for lost margin. Materials may have risen, the client may have changed scope, or the program may have shifted. Business.gov.au says variations are best put in writing and signed by both sides, and that change requests should spell out scope, cost and timeline.

If you have been asked to keep going without a clear variation, treat that as a warning sign. A verbal promise might be real, but it is still easy to argue about later. Put the change in an email or letter, attach it to the contract, and keep the job file tidy.

Talk before you run out of money

Before you call it quits, speak to the builder or client while you still have options. Explain the cost gap plainly, show the extra work or cost pressure, and ask for a written response on what they will pay now and what they will confirm later. Silence usually narrows choices.

That conversation should also test whether there is a practical way to keep the job moving. A milestone payment, a deposit, a narrower scope or a pause with agreed protection may be better than an unplanned walk-off. Business.gov.au says construction payment laws can help recover payment for work already done, but the rules differ by state or territory, so get advice before you stop work today.

Get advice before you stop work

If the job is already beyond easy repair, get your file in order before you make the next move. Pull together the signed contract, quote, variations, emails, site photos, cost-to-complete notes and any payment history so the advice is based on facts, not memory. That record matters later as well.
