An Authentisign alternative for real estate
Real estate e-signing you can price before you call anyone.
Authentisign usually comes bundled with a brokerage software suite. Sign Work Pro is a standalone signing tool for realtors and brokerages, with prices on the website, signing links by text and WhatsApp, and an audit trail you can check yourself.

| Ask | Sign Work Pro |
|---|---|
| Can I see the price without a sales call? | Yes. Plans are on the pricing page: US$4.99, $9.99 and $19.99 a month, flat, with no per-envelope fees. Brokerages pay from US$3.49 per realtor a month. |
| Can I buy it as one agent, without my brokerage’s suite? | Yes. Start a 14-day free trial with no credit card, then pick a monthly or annual plan. Cancel any time. |
| Can clients sign from a text or WhatsApp? | Yes. Links go by SMS, WhatsApp or email (and Messenger or Instagram when you’re already chatting with the client there), with an email fallback if a text fails. |
| What proof do I get? | A hash-chained audit trail, plus a Certificate of Completion added to every signed document. |
| Can I tell if a signed page was changed? | Yes. Every page carries the envelope ID and the signed document’s SHA-256 fingerprint. |
| Can I strike out a term and have it initialled? | Yes. A built-in Strikethrough tool, with the replacement text and initials burned into the final PDF. |
| Where do clients find their documents later? | In a free client portal holding everything they have signed with you. |
| Does it work with my transaction-management software? | Yes. Set the copy email to the transaction’s address in Lone Wolf, zipForm, SkySlope or similar, and the signed contract and its certificate are delivered into that transaction automatically once everyone has signed. Nothing to download or upload. |

Questions
Choosing an Authentisign alternative: FAQ
Why would a realtor look for an Authentisign alternative?
Authentisign is usually bought as part of a brokerage’s software suite, so the choice is often made by the office rather than the agent. Agents who pay for their own tools, or offices that only need signing, sometimes want a standalone tool with published per-agent pricing, text and WhatsApp signing links and a client portal.
Can I use Sign Work Pro if my brokerage already uses a software suite?
Yes. Sign Work Pro works on its own, and it fits alongside the suite you already have: set the copy email to the transaction’s address in Lone Wolf, zipForm, SkySlope or similar, and each signed contract, with its Certificate of Completion, is delivered into that transaction file as soon as the last person signs. No uploading documents yourself.
Is Sign Work Pro legally binding?
Yes. Sign Work Pro captures consent, intent, identity checks and a tamper-evident audit trail, and adds a Certificate of Completion to every signed document. That is the evidence electronic-signature laws such as BC’s Electronic Transactions Act, PIPEDA, ESIGN and UETA look for.
What does it cost for a whole brokerage?
Brokerage licenses are priced per realtor, from US$3.49 a month each, with one license key for the whole office. Individual agents start at US$4.99 a month. You can cancel at any time.
