Sign.Plus report card
Fair · out of 4.0 · graded Oct 18, 2026
Best for qualified signatures and signing by WhatsApp
Sign.Plus, from the Swiss company behind Fax.Plus, has apps for iPhone and Android and can reach signers by email, SMS or WhatsApp. It offers qualified signatures under EU and Swiss rules on every plan too, at $5 a recipient. But Personal is one user and 10 requests a month, and a team pays $19.99 a head.
Who Sign.Plus is for
- Great if your contracts need qualified signatures under EU or Swiss rules
- Handy when your clients answer WhatsApp faster than email
- Good for healthcare teams that need HIPAA with a signed BAA, on Enterprise
Who Sign.Plus is not for
- Tight if you're staying free, with 3 signature requests in total
- Pricey if you're a team, at $19.99 a user a month billed yearly
- Skip it if you want to try it without a card, as the trial asks for one
Why Sign.Plus gets a 2.4
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyPersonal is $9.99 a month billed yearly ($14.99 monthly), at this category's cheaper quarter, but it's one user and 10 requests a month. A team needs Professional at $19.99 a user, past the dearer quarter, and qualified signatures are $5 a recipient on top.
- CFree plan and trialThe free plan lets you sign your own documents, but it's 3 signature requests in total, not per month, and one template. The 14-day trial needs a card or PayPal and turns into a paid plan unless you cancel.
- BFeaturesTemplates with conditional steps, bulk send, in-person signing, public forms, SMS and WhatsApp sends, ID checks and qualified signatures. It covers the whole job across its plans, though Zapier and branding start on Business.
- CEase of useThere are iPhone and Android apps, but no store rating on record. It's a web app where you build templates and workflows before it pays off.
- BPlatforms and integrationsWeb, iPhone and Android, sending from Google Docs, Gmail and Word and pulling files from Google Drive, OneDrive, Dropbox and Box. Zapier is on Business, the API is sold separately, and there's no desktop app.

Keep it
The plain part of Sign.Plus you could make: documents, templates and forms. What surrounds it you could not. The 4 things listed below take a company, not a weekend.
It costs $119.88 a year.
What you could make
- Documents, templates and forms: an app builder makes these well.
What you could not
- A real app for iOS and Android. Something home-made would be a web page.
- It plugs into other products, Google Docs, Gmail and Google Drive among them, and has an API.
- What a company asks for before it lets staff use something: SOC 2 and HIPAA.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Sign.Plus’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
