How it works
A contract variation, put in writing and signed by both parties, in a few minutes.
- Fill it inWho is sending it — the builder, a trade contractor or the owner — the state, both parties, the project, site and contract, what changes, and the price, line by line. Add the photos, quotes or drawings that back it; they go in after the signatures as numbered annexures. The net change, GST, total and revised contract price are worked out as you type, and the document builds beside the form. The preview is free.
- Sign and sendType your name and draw your signature. Pay for the document, or use one from a pack. We email the other party a link to read and sign it, with the PDF attached, and send you your copy. The first time you send from an email address, we email that address first, and the variation goes when you press Send — so nobody can send one in your name from an address they don't read.
- They sign from the emailThey open the link on a phone or a computer, read the variation and everything attached to it, tick that they agree to sign electronically, type their name and draw their signature. If they don't agree, they decline it and say why, and you're told.
- You both get the signed PDFIt ends with a signing record: each signature with the time in your state, the device and internet address it came from, and the consent given. If it isn't signed after 3 days we remind them, and again after 7.
- Keep the job's registerSign in with the email address you paid with — no password, we email you a link — and every variation you've sent is listed under its job, by project name or site address: where each one is up to, its PDF, and the contract price as each one is signed. Send a waiting one again, or start the next variation on the job with the parties, project, site and contract price carried forward.
The document follows your state
The statement printed on the document, the fields the form asks for and the hints beside them change with the state or territory of the site. Each state page sets out what its law says about variations, with the section and a link to the Act.
- New South Wales
- Victoria
- Queensland
- Western Australia
- South Australia
- Tasmania
- Australian Capital Territory
- Northern Territory
Is an electronic signature enough?
The Electronic Transactions Acts of New South Wales, Victoria, Queensland, Western Australia, Tasmania, the ACT and the Northern Territory, and South Australia's Electronic Communications Act, accept a signature given electronically when the method identifies the person and shows their intention, is reliable enough for the purpose, and the other party consents to it. VaryPro records each part: the consent each signer ticks, the email link they signed through, and the time, device and internet address of each signature. The exclusions in the Victorian, Queensland, Western Australian and South Australian laws (such as wills, powers of attorney, witnessed documents and court filings) don't include building contracts, and no regulator guidance we read says anything either way about signing a variation electronically. This is not legal advice — your contract and your state's rules come first.
What VaryPro is not
VaryPro prepares and delivers the document and records the signatures. It isn't a party to your contract, it doesn't check your figures against your contract, and it doesn't give legal advice.
VaryPro doesn't check who sends a variation, and a variation isn't a bill. If one asks you to pay into a new bank account, check with the sender on contact details you already have.
