Sign documents. Stay in control.
Secure electronic signatures for Australian finance, insurance, and professional services teams. Send, track, and complete documents with tamper-evident audit trails.
Or run it from your AI: connect SignAndGo to ChatGPT or Claude and ask it to send documents, chase signers, and file signed PDFs. See how it works →
Bring your own AI.
Ask Claude or ChatGPT about your envelopes. Get instant status across your workspace, surface stalled signers, draft sends from existing templates, void or remind in a single message, all without leaving the chat.
First Australian e-signature platform with native Model Context Protocol (MCP) support. Your AI sees only the envelopes you allow, with separate consent gates for read and write. DocuSign, Adobe Sign, Annature don't offer this.
File uploads and bulk write operations work best from Claude Desktop, ChatGPT Desktop, or custom MCP clients. Supported environments →
The signing experience your recipients actually enjoy. Clear fields, one-tap signing, a tamper-evident trail on every document.
Built for teams who need more than a signature
Scattered approvals slow you down
Create structured signing workflows with sequential or parallel routing. Track every envelope from one dashboard.
Audit gaps create compliance risk
Every action is logged with a tamper-evident hash chain. Download verifiable audit certificates for each completed document.
Shared logins and weak access controls
Assign roles and permissions per user. Separate teams with workspace and subgroup isolation.
More than just signatures

ABN Lookup
Enter an ABN and we auto-fill company name, entity type, and GST status from the Australian Business Register.

Everything you need to manage document signing
AI-Powered Template Library
14 professionally drafted Australian legal templates: NDAs, leases, employment contracts, and more. Our AI assistant customises them with your details in seconds.
Edit directly on the document
Double-click any text field to type directly on the PDF. Pre-fill names, dates, and amounts before sending. Your recipients just sign.
Sharna: AI Assistant
Our 24/7 AI assistant helps you create documents, choose templates, and troubleshoot issues. Ask Sharna anything. She knows SignAndGo inside out.
Your own templates
Save frequently used documents as templates. Add recipients and fields once, then reuse for every new signing request.
Automatic reminders
Set reminder schedules per envelope. Recipients receive follow-up emails until they sign.
Tamper-proof audit trail
Every signature event is cryptographically chained. Verify the integrity of any document's history at any time.
Access controls
Assign admin, sender, or viewer roles. Control who can create, send, and manage documents across your team.
Workspace separation
Isolate data by workspace. Subgroups let you control access within a workspace for different teams.
Anti-Fraud Protection
Device fingerprinting, VPN and proxy detection, and geographic controls to prevent fraudulent signing attempts.
Developer API
Full REST API with Bearer token authentication, real-time webhooks, and scoped API keys with granular permissions.
Folders and filters
Organise envelopes by status, date, or custom folders. Find any document in seconds.
Document Verification
Every signed document gets a unique verification ID. Anyone can verify authenticity at signandgo.com.au/verify. No uploads needed, just the ID.
AI Document Summary
Signers can request a plain-language AI summary before signing. Highlights key obligations, rights, and potential concerns. A reading aid, not legal advice.
Drag & Drop Everything
Drag files to upload, drag to reorder documents in bundles, drag recipients to set signing order, and drag fields with snap-to-grid precision.
Witnessed signatures
Add a witness to any signature. They receive their own secure link once the signer has signed, and how they verified identity is recorded in the audit trail.
Approvals and countersigning
Require an internal approval before anyone is asked to sign, or place the approver last so a manager countersigns to complete. Approvers review without placing a signature.
Send to view
Not everything needs a signature. Send a notice or policy for review, get told the moment it is opened, and receive a receipt when it is acknowledged.
In-person signing
Sign on the spot at a counter, on site, or across a desk. Hand over your own device and capture the signature there, with the same audit trail as a remote signature.
Ask signers for documents
Place an upload field and require a licence, certificate, or proof of insurance alongside the signature. Every file is virus-scanned before anyone can open it.
Web forms
Publish a link that anyone can fill in and sign, with no envelope to send first. Ideal for onboarding, consent, and intake that arrives on its own schedule.
Collect payment at signing
Take a deposit or fee at the moment of signature, so the agreement and the payment happen together instead of chasing an invoice afterwards.
Verify who is signing
Require a signer to check their government ID with a liveness selfie before they can sign. Set it per document or as a default, and the result is recorded in the audit trail.
Contract analysis
Run an AI review over a contract before it goes out. Surfaces obligations, dates, and unusual terms so nothing is signed unread. A reading aid, not legal advice.
Fits the tools you already run
Signed documents should land where the work already happens, not in another inbox to be filed by hand.
Xero
File signed documents straight onto the right contact, and create contacts from your signers. Connect several organisations, across more than one Xero login.
