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.

SignAndGo, by contrast, uses flat monthly plans starting free, with a $59/month AUD Professional plan that includes 100 envelopes.
Is SignAndGo a good Annature alternative?
If you send documents regularly and want predictable monthly costs, SignAndGo's flat plans with included envelopes are designed for exactly that. If you send only occasionally, a per-envelope model like Annature's can suit low volumes. Estimate your monthly envelope count, then compare against SignAndGo's plan inclusions.
SignAndGo vs Annature: what is the main difference?
The core difference is the pricing model. Annature charges per envelope ($1.75 each as of 28 June 2026); SignAndGo charges a flat monthly fee with envelopes included. SignAndGo also ships Australian-specific tooling (ABN Lookup, GST calculator, 14 Australian legal templates) and AI features including a connector for Claude and ChatGPT.
Are both SignAndGo and Annature hosted in Australia?
Yes. SignAndGo hosts on Google Cloud in Sydney (australia-southeast1) with Australian data residency. Annature hosts on AWS in Sydney (ap-southeast-2), per annature.com.au/trust-security (checked 28 June 2026). Both keep data onshore in Australia.
Is SignAndGo’s e-signature legally binding in Australia?
Yes. Electronic signatures are legally binding in Australia under the Electronic Transactions Act 1999 (Commonwealth) and each state and territory's equivalent Act, provided the signer consents and is identified. Every document signed with SignAndGo carries a tamper-evident audit trail with cryptographic hash-chain verification, timestamps, and a verification stamp to evidence each signing event.
Which is cheaper, SignAndGo or Annature?
It depends on volume. At low volumes, Annature's $1.75 per envelope (as of 28 June 2026) can be cheaper. Once you send dozens of documents a month, SignAndGo's flat plans (for example $59/month AUD for 100 envelopes on Professional) typically work out more predictable and lower per-document. Calculate your expected monthly volume to compare.
What is the best e-signature software for Australian businesses?
The best fit depends on volume, sector and feature needs. For Australian finance, insurance and professional-services teams that send regularly and want predictable pricing plus AU-specific tooling (ABN Lookup, GST calculator, AU legal templates), SignAndGo is purpose-built. For occasional senders who want pay-as-you-go billing with built-in identity verification, Annature is a strong Australian option. Both host data onshore in Sydney.
