DocuSign and Adobe Sign are US-headquartered platforms; data may be processed in US facilities subject to the CLOUD Act and Patriot Act. Annature is an Australian platform — a fair local competitor.
What Makes SignAndGo Different
Every feature built with the Australian business in mind — not retrofitted from a US platform.
Legal Compliance (ETA 1999)
Every signed document meets the requirements of the Electronic Transactions Act 1999 (Cth) and state equivalents. Tamper-evident audit trail admissible in Australian courts.
100% Sydney Data Residency
All documents, metadata, audit trails, and backups stored in Google Cloud australia-southeast1. No overseas transfer. Aligns with Australian Privacy Principles (APP 8).
AI Field Detection
Gemini AI scans your uploaded PDF and places signature, initials, date, and name fields automatically — no manual drag-and-drop for common forms.
14 Australian Legal Templates
NDA, employment, contractor, lease, service agreement, deed of release, power of attorney, and more — drafted for Australian law, not retrofitted from the US.
Remote Witness Signing
For property deeds and documents that require a witness, SignAndGo supports fully remote electronic witnessing — rare in this category, essential for Australian legal use.
Verification Stamps
Every signed PDF gets a public verification URL — anyone with the document can confirm it was signed via SignAndGo and hasn't been altered since.
Team Workspaces
Invite your team, manage shared templates, track envelope status, enforce consistent branding. Role-based permissions for admin, sender, and signer.
Developer API + Webhooks

The Legal Foundation of Australian eSignatures
Australia recognised the legal validity of electronic signatures in the Electronic Transactions Act 1999 (Cth). Under section 10 of the Act, a signature requirement is met electronically if three conditions are satisfied: (1) the method used identifies the person and indicates their intent to sign, (2) the method is reliable in the circumstances, and (3) the other party consents to the electronic method.
Every Australian state and territory has passed mirror legislation: Electronic Transactions Act 2000 (NSW), the Electronic Transactions (Victoria) Act 2000, the Electronic Transactions (Queensland) Act 2001, the Electronic Transactions Act 2011 (WA), plus SA, Tas, ACT, and NT equivalents. For the vast majority of commercial and personal documents in Australia, an electronic signature has identical legal force to a handwritten one.
SignAndGo exceeds the Act's reliability requirement through a layered evidentiary stack: IP address capture, geolocation, device fingerprint, timestamped audit trail, tamper-evident PDF seal, and a public verification URL per document. If a signed document is ever contested in court, the evidence is ready on day one — not reconstructed under subpoena.
