SignAndGo and Annature are both Australian-built e-signature platforms that keep your data onshore.
The genuine difference is the pricing model. SignAndGo is a flat monthly subscription with included envelopes, built for finance, insurance and professional-services teams. Annature is a pay-as-you-go, per-envelope platform with built-in identity verification and payments. Different models suit different volumes.
Here is how the two stack up on the dimensions that matter most to Australian businesses. Every Annature figure links to Annature's own published page and the date we checked it (28 June 2026).

Per-envelope pricing like Annature's can be more economical at low volumes; a flat plan like SignAndGo's becomes more predictable and often cheaper once you send regularly. Work out your monthly envelope count and compare.
A fixed plan beats per-envelope billing once volume is steady. Professional is $59/mo AUD for 100 included envelopes, so a regular sender knows the bill in advance.
ABN Lookup auto-fill, a GST calculator, 14 Australian legal templates, and Xero and Procore integrations, made for finance, insurance and professional-services teams.
An AI assistant (Sharna), AI document preparation and summary, and an AI connector for Claude and ChatGPT via MCP, so you can drive signing from the tools you already use.
