The paperwork part, in plain English.

A variation letter is one page: what changed, what it costs, how long it adds, signed before the work starts. Free copy-ready template for Australian trades.

Daywork is extra work charged at agreed hourly and daily rates instead of a fixed price. Free copy-ready sheet for time, plant and materials.

How variations work on Australian jobs: what counts as one, who signs, what each state expects in writing, and the habit that gets extras paid.

NSW home building contracts require variations in writing, signed by both parties. What the Home Building Act expects, and how builders comply without slowing down.

Queensland regulated contracts need a compliant written variation document and the owner's written agreement before varied work starts. Schedule 1B, plainly explained.

Victorian major domestic building contracts need a written variation notice and signed consent before varied work starts. Sections 37–39 of the DBCA, in plain English.

A signed variation gets paid; an unwritten one gets argued. Why customers dispute extras, what strengthens your position, and your options when they stall.

Proof of approval answers three questions: what was agreed, when, and whether both sides saw the same words. The evidence ladder, strongest to weakest.

A verbal agreement can be real, but proving it is another matter. How Australian states treat written variations, and what a signature actually buys you.

Scope creep isn't one big request — it's ten polite ones. Where it comes from, the three habits that stop it, and scripts for the moment it starts.

ServiceM8's Contract Variation Form is a real feature — here's how to build it in Settings, what plan you need, and how staff run it from the job's To Do tab.

Simpro has two kinds of variation: a cost centre on the job, or a linked variation quote or job. When to use each, and where the approval gap sits.

Tradify doesn't have a variation feature — it revises quotes. How quote revision and customer signatures work, and what to do about extras mid-job.

Fergus has a proper Variations feature — extra work gets its own job number and tracks through to invoicing. How to create one, and the approval it doesn't capture.

Same mechanism, different word. Australian contracts say variation, American ones say change order. The word matters less than getting the change in writing.
