The contract runs itself.

A building contract is a set of mutually binding promises with deadlines attached. Every notice has a clause it answers to, every claim has a date it dies on, and every certificate has a moment it must exist by. Miss one and you don’t lose the argument — you lose the money. eSiteOffice writes those documents, serves them, and watches every date, for whoever is running the contract.

Built by a NSW construction lawyer who has run building companies. “I’ve developed projects, built them, and litigated them. Cashflow is the lifeblood of construction. Without a written record, someone gets squeezed — whether it’s the owner, the builder, or the trade.” — Michael Phontos

Why it exists — the $1,600 variation that ended up in the Supreme Court

A builder hits buried concrete under a driveway. He photographs it, texts the client a $1,600 quote, gets back “fair enough, go ahead”, and does the work. Everything about that was honest.

That $1,600 became one of over 60 disputed claims, ran from the tribunal to the Supreme Court, and the two sides spent more than $500,000 in legal costs.

The paperwork the contract wanted for that claim should have taken five minutes — before the work started.

The document the contract asked for

Here is that variation as eSiteOffice draws it — with its schedules, priced, and waiting to be served. The three stages across the top are the contract running: draft and serve, their response, your reply — each with its own deadline.

A Variation Notice in eSiteOffice: a three-stage bar reading Draft & Serve, Response, Reply across the top, and beneath it the drafted notice on the builder’s letterhead citing Clause 13, with the variation priced at $1,455 plus $145 GST.

Try the part that’s already running

Construction contracts and Security of Payment legislation impose strict time limits. Miss them and valuable rights to payment can disappear.

eSiteOffice was built because those dates shouldn’t have to live in someone’s diary.

The drafting opens in September. The counting is live now. This site includes two free payment clocks that work out the statutory timetable from your answers about a payment claim. They ask questions because the website doesn’t know your contract. eSiteOffice does. In the app, the contract is recorded once, and every notice, claim and deadline is dated from its terms.

Who it’s for

The same contract looks different depending on which seat you’re in — but everyone in it owes documents, and everyone in it is owed documents. eSiteOffice runs the contract from whichever seat you occupy.

Owner-builders

You’ve taken the builder’s seat — the margin, and the legal position that comes with it — without a builder’s back office. Trades price you higher, banks lend you less, and both are reading the same thing: how organised you look.

Starts here — you engage the trades yourself →

Builders

Every variation, every progress claim, every extension of time is a clause with a deadline attached — across every job at once. The ones that cost you are never the ones you argued about; they’re the ones that quietly expired.

Starts here — you run jobs for a living →

Trades & subcontractors

Getting paid is a paperwork problem before it’s a money problem. The claim you didn’t make properly, the certificate you didn’t hand over, the back-charge you didn’t answer in time.

Starts here — you’re at the end of the chain →

Owners

Your builder holds a stack of documents the law says are yours — the contract, the licence, the insurance certificate that had to exist before you paid a deposit. And the change made on site and written down afterwards is the one you end up arguing about.

Starts here — someone else is building for you →

Strata managers

Repair and capital works on residential common property are residential building work, and the owners corporation’s duties reach you through the delegation. Where a delegated function is breached the offence lands on the agent — unless you can establish you took all reasonable steps. That is a file, and you need it on every scheme at once.

Starts here — you act for the owners corporation →

What it does, in plain terms

Writes the paperwork the law requires

The right contract for each engagement, the notice with the clause it answers to, the letter that starts the clock — drafted for you, not by you.

Watches every deadline

Time bars, response windows, insurance expiries, certificates due before money moves. The clock is watched so you don’t carry it in your head.

Keeps the record that wins

Every document served, dated, and filed with its proof. If a dispute ever comes, you hold the chronology — not a shoebox of texts.
