WHAT SUBSYNC IS

SubSync is contract software for subcontractors.

SubSync is a web application you sign in to. You upload the subcontract a builder has handed you, and SubSync reads it, so you know what you are agreeing to before you sign. Once the job is running, the same contract drives the paperwork that keeps you paid — the notices, the claims, the orders and the records behind them.

Contract review

Upload a subcontract and get a plain-English commercial review: the terms that matter, each one risk-rated against what the industry actually accepts, and a departure schedule you can take back to the builder.

Contract notices

Say what happened on site and SubSync drafts the notice — extension of time, variation, payment, defects — against your own contract's clauses, and counts the time bar in business days so the deadline is not a guess.

Variations and claims

Quote a variation, follow it from submitted to approved, and build the progress claim off what has actually been approved — so what you claim and what you are owed are the same number.

Orders and agreements

Turn a supplier's quote into a purchase order or a subcontract agreement on your own template, keep track of where each one is up to, and send the approved ones through to your accounting platform.

Site records

Diaries, photos, delays and inspections captured on a phone from site and kept against the job — so when a claim needs evidence months later, the evidence is already sitting there.

Supplier invoices

Supplier invoices land in SubSync, get coded against the job they belong to, and go through your approvals before anyone pays them or sends them to the books.

Connecting your email account is optional

Most supplier invoices arrive by email, and re-typing them is the job nobody wants. So SubSync can connect to an email account you already own — Gmail or Microsoft 365 — with your permission, to find the supplier invoices sent to it and code them against your jobs. You choose whether to connect an account, and you can disconnect it at any time.

SubSync asks only for permission to read that mailbox, and uses it only to find supplier invoices and their attachments. It never sends, deletes or changes email, and nothing it finds is paid, posted to your accounting platform, or acted on until a person in your business approves it.

SubSync's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements. Our Privacy Policy sets out what we do and do not do with mailbox data.

THE PROBLEM

Reviewing a subcontract shouldn't cost you a weekend.

Most Subcontractors sign without a real subcontract review — contracts they haven't read, terms they don't fully understand, deadlines that never feel reasonable. The risk lands on you — not the head contractor. Subcontract review software closes that gap for a fraction of what a lawyer charges to read the same sixty pages.

01

Hours, not minutes

A 60-page head-contract pass-through eats 1–2 hours of your time. SubSync does a commercial review in 15–20 minutes.

02

Hidden risk

Pay-when-paid, uncapped liability, indemnities, builder's discretion on what they pay you. Dangerous clauses are buried in plain sight.

03

Legal review costs a fortune

A proper legal review runs into the thousands per contract, and you might not even win the work. So most Subcontractors sign without one and carry the risk.

04

Notices fall through the cracks

Miss a delay notice or variation claim and your right to be paid disappears. The clock is unforgiving.

HOW SUBSYNC WORKS

Three jobs, handled.

From review to notice to agreement — the whole subcontract lifecycle in one place. SubSync is subcontract review software built around what happens after you sign, not just before.

Feature 01 Contracts

Upload, review, decide.

Drop in any subcontract or head-contract pass-through. SubSync flags risk, explains it in plain English, and gives you talking points based on common industry positions.
Feature 02 Notices

Notices in seconds.

Delay, variation, EOT, payment claim, suspension. SubSync drafts the right notice against the right clause — ready to send.
Feature 03 Orders

POs & Subcontract Agreements, drafted.

SubSync generates Purchase Orders and Subcontract Agreements from your quotes using your own templates. Auto-populated key parameters, ready for review.
Feature 04 Coming Q3 2026

Push terms downstream.

FEATURES

Built for how Subcontractors actually work.

Four tools, one workflow that respects your time on site. Built in Melbourne, for subcontractors on Australian commercial projects — the subcontract review software we wanted when we were the ones signing.

AI Commercial Reviewer

Plain-English commercial risk reviews.

Upload a head-contract pass-through or any subcontract and get a structured, plain-English commercial risk review in 15–20 minutes. Every flag links back to the exact clause, with a recommended position and a summary of common industry positions to take into negotiation.

  • Risk-rated clauses (high / medium / low)
  • Clause-by-clause explanations a non-lawyer can act on
  • Summary of common industry commercial positions
  • Side-by-side benchmark vs typical industry position
  • Departure schedule ready to send to the builder

New to this? Read what a departure schedule is and why builders respond to one better than a marked-up PDF, or start from the departure schedule template.

FAQ

Questions subcontractors actually ask.

Is SubSync legal advice?
No. SubSync provides commercial benchmarks and risk flags drawn from Australian construction-industry practice. We are not a law firm and our outputs are not legal advice, contract interpretation, or a professional legal opinion. We operate under a Legal Advice Exclusion as part of our insurance cover.
What contracts can I upload?
Any subcontract or head-contract pass-through: AS 4902, AS 4903, AS 2124, bespoke head contracts, and short-form trade agreements. PDFs and Word files, up to 40 MB.
How accurate is the AI?
Every flag cites the exact clause it's drawn from. Reviews are benchmarked against typical Australian commercial positions for construction subcontracts. We recommend treating outputs as a first pass that surfaces risk — not a replacement for your own commercial judgement.
Does it know state-specific Security of Payment legislation?
Yes. SubSync is aware of SOPA in NSW, VIC, QLD, WA, SA, NT, TAS and ACT. Pay-when-paid clauses, for example, are flagged against the void-and-unenforceable provisions in each state's SoP Act.
Will my contracts be used to train AI models?
Never. Your documents are not used for model training and are not shared with third-party model providers in identifiable form.
