What makes Siggy different: the space between e-signature suites and proposal tools

Last updated 27 October 2026

There are two kinds of signing software: the big per-seat suites and the proposal tools that end with a signature. Siggy is built for the Australian practice in the middle, where an agreement needs a verified identity, a signature and a payment in one step.

If you shop for signing software today you meet two families. On one side are the suites, DocuSign chief among them: enormous, trusted, priced per user, built for a sales floor or a legal department that sends thousands of envelopes a year. On the other are the proposal tools, Qwilr, PandaDoc and their cousins: web pages that sell, with pricing tables and videos, where the signature is the last section of the pitch and the payment is a checkout at the bottom.

Australian practices sit between the two: the accountant with four staff, the NDIS provider with thirty participants, the builder with a quote book, the clinic, the adviser. They do not send pitch decks. They send agreements: engagement letters, service agreements, deeds, declarations, contracts. And the thing they actually need from an agreement is not a nicer-looking page. It is for the client to be who they say they are, to sign, and to pay, in one step, with a record that will hold up years later. That gap is what Siggy is built for.

Priced for a practice, not a seat

Both families price per user. DocuSign's Australian plans are per user per month with an envelope allowance per user, and Qwilr's are per user with minimum seat counts on its higher tiers (sources 2 and 3). A five-person practice pays five times. Siggy's plans are per practice: Professional includes 5 team members and 100 envelopes a month for $15 a month, Business 15 members and 200 envelopes for $20, and a busy month costs a dollar an extra envelope rather than a plan change. The pricing page has the full grid, and the DocuSign comparison does the arithmetic with DocuSign's published Australian figures.

Identity, signature and payment in one envelope

An agreement with a stranger has three questions in it. Who is this? Do they agree? Have they paid? Siggy answers all three from the same link your client opens on their phone.

  • Who is this. Identity verification checks an Australian driver licence, passport or Medicare card against the issuing authority's records, with a face match and PEP and sanctions screening, from $6.00 a check. It is the check the TPB and the AML/CTF regime expect, built into the signing flow rather than bolted on.
  • Do they agree. Sequential or parallel signing, drawn or typed signatures, access codes, SMS links, reminders, a tamper-evident seal and a Certificate of Completion that records the who, when and where of every signature.
  • Have they paid. Payments on signing: a one-off, recurring, or both, by card or bank debit through your own Stripe account, with the signed copies released only when the money is in. Siggy keeps 0.5%, capped at $5 on a one-off payment; Stripe's fees apply as usual.

Australian, in the ways that matter

Siggy is built and hosted in Australia, with Australian data residency and an Australian support inbox that answers in Australian hours. The content library is written for Australian law: whether a deed needs a witness in your state, what the ATO accepts on a client declaration, what tranche 2 means for an accounting practice. Bank debit at signing means BECS, not ACH. Identity checks run against Australian documents. None of this is exotic; it is simply the default here, where elsewhere it is a localisation.

The honest limit is scale. If you are a national firm sending tens of thousands of envelopes with a procurement team and an SSO requirement, the suites are built for that and we would say so; Enterprise is a conversation, not a checkout. And if what you send is genuinely a pitch, a page that needs to sell before it is signed, a proposal tool earns its keep. Siggy is for the moment after the pitch, when the agreement needs to be real.

The middle, on purpose

The suites made signing legal and boring, which is a compliment. The proposal tools made the sales document beautiful. Neither was built for the Australian practice whose agreements are the business: the engagement letter that starts the year, the service agreement that starts the support, the contract that starts the build. Siggy takes the one thing each family does well, legally sound signing on one side, a payment where the yes happens on the other, and adds the thing neither does: a verified identity on the same link, priced so a four-person practice can afford to use it on every client.
