Getting paid
The work got done. The argument starts at invoice time.
Almost nobody refuses to pay a variation to your face. What happens instead is quieter: the invoice lands, the replies slow down, and suddenly the extra work you did on a nod is “not what I understood”. Here's why that pattern runs, what actually strengthens a claim, and what to do when it's already happening.
Why variations stall What weakens a claim The chase, in order
01 — The pattern
Nobody refuses. They just stop replying.
The unpaid variation rarely dies in an argument. It dies in the gap between doing the work and invoicing for it — weeks in which the customer's memory quietly rearranges itself around what they remember agreeing to, which is usually less than you remember, and cheaper.
That's why “they seemed happy at the time” counts for so little afterwards. Happiness at handover isn't approval of scope and price — it's relief that the job's finished. The only thing that survives the gap intact is paper both sides signed while they still agreed.
02 — What weakens you
Four habits turn a fair claim into a coin flip.
Starting before sign-off
Once the work exists, agreement becomes retroactive — you're negotiating with someone who already has the benefit.
Vague descriptions
“Extras as discussed” describes nothing a third party can price. If the wording wouldn't survive being read aloud to a stranger, it won't survive a dispute.
No time impact recorded
The delay claim arrives attached to the money claim. A variation that priced the work but never recorded days added hands them half the argument free.
Invoice as first paperwork
If the line item's first appearance is the invoice, its entire history is your word. The invoice documents a charge; it doesn't document an agreement.
03 — When they've gone quiet
The chase, in order, without torching the relationship.
Resend the signed variation
Plain cover note: “Resending the variation we agreed on 12 August — flagging it rides with Friday's invoice.” No emotion, just the document back on their screen.
Offer the call, confirm in writing after
Phone calls move things — then evaporate. Whatever gets said, send the two-line summary afterwards: “As discussed, the additional fencing at $1,430 inc GST proceeds Thursday.”
Formal second letter
Amount, what it covers, when it was approved, due date, and the next step if it stays unpaid. Factual, not furious — this letter is evidence now.
The last resorts
Each state runs a civil tribunal for building disputes (NCAT in NSW, QCAT in Queensland, VCAT in Victoria), and industry associations offer mediation. Keep working other jobs either way, and don't self-help by withholding anything you hold — that converts your good claim into their counterclaim.
04 — If nothing was signed
Unwritten variations can still recover something. Just harder.
Where residential contracts require written variations — NSW, Queensland and Victoria each do it their own way — the contractual claim generally fails without one, and what's left is a fallback asking a tribunal to value the work reasonably after the fact. Texts, photos and progress records all help build that picture; they're just reconstructing an agreement that should have been captured in a minute at the time.
None of this is legal advice — live disputes belong with someone qualified. But the direction of travel is simple: the cheapest debt collection is a signature collected before the work started.
Straight answers
Questions people actually ask.
Can I stop work until they pay for the last variation?
It depends entirely on your contract — some allow suspension on notice, some forbid it, and payment legislation adds rules of its own in each state. Stopping without checking converts your payment claim into their breach claim. Read the contract first; if it's live or large, get advice before you put the tools down.
Is a text message approval enough to enforce payment?
A text showing the price sent and some positive reply is real evidence — far better than nothing. Its weakness is wording: it shows a number travelled, not that both sides agreed the same scope behind it. A signed one-pager beats a thread every time, but a bad text beats no record at all.
Do I need a lawyer to go to the tribunal?
Small building claims are designed to run without one, and tribunals are deliberately less formal than courts. Whether your matter suits that track depends on the amount and complexity in your state — many people run small claims themselves and spend the money that saves on getting the paperwork right next job.
How do I stop this happening again?
One habit: no varied work starts until there's a signature against the wording — scope, price including GST, days added, dated both sides. It takes about a minute on site with the right tool and it deletes this entire page from your future. The template guide shows the seven things it needs to contain.
