For Procore firms, pull Commitment Contracts, sign, and push the signed PDF back to the source contract automatically.

Australian data residency

Documents and audit trails hosted in Australia, aligned with the Australian Privacy Principles.

Flat AUD pricing

Signing that fits a construction business

Construction runs on contracts: subcontracts, supply agreements, variations, and purchase orders, often signed by people who are on site rather than at a desk. SignAndGo lets a subcontractor sign from a phone with no app or account, supports in-person signing, and can even capture a paper document by photo to sign on the spot. Every signature is legally binding under the Electronic Transactions Act 1999 and carries a full audit trail and a tamper-evident verification stamp.

If you run Procore, the integration goes further: pull a Commitment Contract (Work Order or Purchase Order Contract) straight from the project, get it signed, and the signed PDF is pushed back to the source contract automatically with the status set to Approved. Documents and audit trails are hosted in Australia, and pricing is flat and in Australian dollars with no per-signer fees.

Frequently asked questions

Are construction contracts legally binding when signed electronically in Australia?
Yes. Electronic signatures are legally binding under the Electronic Transactions Act 1999 (Commonwealth) and each state and territory equivalent. This covers subcontracts, supply agreements, variations, and purchase orders. SignAndGo records a full audit trail (timestamp, IP, email verification) and a tamper-evident verification stamp on every signed document, which is the evidence you want behind a construction contract.
Can subcontractors sign on their phone on site?
Yes. Signers complete documents on any device with no app or account required, so a subcontractor can sign a contract or variation from their phone on site. SignAndGo also supports in-person signing and capturing a document by photo for signing on the spot.
Does it integrate with Procore?
Yes. For firms running Procore, SignAndGo pulls Commitment Contracts (Work Order Contracts and Purchase Order Contracts) straight from the project, gets them signed, and pushes the signed PDF back to the source contract automatically with the status set to Approved. See the Procore subcontractor signing page for details.

SignAndGo is a flat monthly per-workspace subscription in AUD, from a free Personal plan up to Business at $99 per month, with no annual lock-in and no per-signer fees. The Procore integration is available on Business and Enterprise. Subcontractors and recipients are never charged.
