Every dollar of negotiating power you will ever have with a contractor exists before you sign. The moment the contract is executed and the trade is on site, the market disappears and you’re a customer who can’t leave. That asymmetry is why negotiation isn’t haggling — it’s the last cheap decision in the whole engagement.
Rule one: never negotiate an unlevelled quote
Negotiating a total you don’t understand just moves an unknown number down. Level the quotes first — line by line, blanks chased, allowances benchmarked — so you know what you’re buying before you argue about what it costs. The quote comparison guide covers the method; the levelling spreadsheet does the bookkeeping.
Levelling also hands you your negotiating material. “Your piering allowance is half the other two quotes” is a conversation. “Can you do better on price?” is a shrug.
What’s actually negotiable (and what isn’t)
Trades don’t move much on labour rates — and squeezing the rate is how you end up with the B-team on your job. The movement lives elsewhere:
| Lever | What to ask for | Why they’ll move |
|---|---|---|
| Allowances | Re-quote lowballed PC/PS items at realistic rates | Costs them nothing now; honest trades prefer it |
| Provisional sums | Convert PS items to fixed prices where scope is knowable | Certainty for you, a job they can program for them |
| Deposit | The state-capped or lower figure, not “half up-front” | Legal exposure is on them — check the ask with the deposit checker |
| Payment schedule | Payments behind completed, inspected work | Reasonable trades expect this; the resistant ones are telling you something |
| Exclusions | Price the exclusions now, in writing | An excluded item priced today is competition pricing; excluded until mid-build is variation pricing |
| Scope bundling | A sharper price for two packages together | Real saving for them: one mobilisation, one program |
The contract terms worth more than the price
Owner-builders negotiate the total and sign whatever paperwork arrives. Professionals do the opposite — because these clauses decide what the job actually costs:
- Variations in writing, priced before work proceeds. The single most valuable sentence in the contract. Verbal variations at mid-build rates are where five figures leak — see variation creep.
- Payment tied to milestones, not dates. “On completion of frame inspection” beats “30 days from signing” every time. The bank structures drawdowns this way for a reason; mirror it.
- Fixed price over cost-plus wherever the scope is documented. Cost-plus transfers every risk to you and removes the trade’s incentive to be efficient.
- A defects liability period (six months is common on trade packages) with a small retention or final payment held against it. Your leverage after handover is whatever the contract kept for you.
- Start date, duration and a communication clause for delay. You don’t need penalty regimes on a trade package — you need the right to know, in writing, when the program slips, because your slippage compounds across every following trade. The delay-cost counter shows what a fortnight actually costs you.
- Inclusions as a schedule, not a conversation. Anything you discussed that isn’t written down was never agreed.
How to run the conversation
- Negotiate from the levelled sheet, not from feelings. Every ask points at a specific line: an allowance, a blank, an exclusion, a PS.
- One round, in writing. Send the levelled findings, ask each shortlisted trade to respond on the specific items, give a real deadline. Endless rounds burn goodwill with the trades you actually want.
- Trade certainty, not just money. Flexible start windows, decisions made on time, prompt payment behind milestones — these are worth real dollars to a contractor and cost you nothing. Say so, and use them as currency.
- Let the price stand if the terms move. A quote at full price with realistic allowances, a lawful deposit and a written variations clause routinely beats a “discounted” quote without them.
Red flags that end the negotiation
Won’t put variations terms in writing. Insists on the oversized deposit “for materials”. Gets vaguer, not sharper, when you ask about specific lines. Pressures you to sign before a deadline that exists only in the conversation. Any one of these is the negotiation telling you what the build will be like — believe it, and use the second-place quote.
When to get help
Negotiating one trade package from a levelled sheet is very doable. Doing it across every major package, knowing which allowances are fantasy and which asks the local market will actually wear — that’s the $290 Quote Teardown: you get the findings and the specific asks, and you run the conversation holding them.
