SIGNiX

Which one is for you
Pick Adobe Acrobat Sign if
- Fits if your team edits PDFs in Acrobat already and wants signing included
- Works for teams that send many agreements, since team plans put no cap on e-signatures
Look elsewhere if
- Skip it if you only want e-signatures, as you're paying for a whole PDF editor
- Not for you if you might cancel early, as every plan is a year's commitment and leaving late costs half of what's left
- Too light for regulated work, as Adobe keeps its full compliance for Sign Solutions, sold through sales
- Pricey if you want bulk send or branding, which need Pro at $23.99, or the AI Assistant, an add-on below Studio
- Watch out: the Sign phone app is rated 2.2 on iPhone, and no Android app is listed
Pick SIGNiX if
- Fits if you work in banking, title or insurance and want a tamper-evident digital signature
- Makes sense if you also need remote online notarization from the same vendor
Look elsewhere if
- Skip it if you want to try before paying, because there is no free plan or trial
- Pricey if you want your logo on it, since custom branding is $499 a year on top
- Not for you if you need the API on a small plan, as it is Enterprise and quoted
- Watch out: the page shows $180 a seat but also a 100-transaction minimum billed at $300, and does not explain how they fit
- Watch out: remote notarization is a separate product from $299 a year plus $10 a transaction
How we grade them
| 1.6GPAAdobe Acrobat SignWeak | 1.6GPASIGNiXWeak | |
|---|---|---|
| Value for money | CAbout $51 a month for three on Acrobat Standard for teams, at $16.99 a licence on the annual plan billed monthly. That's the dearer end of this category, but it includes a full PDF editor and uncapped e-signatures. Bulk send and branding need Pro at $23.99. | C$180 per user a year is $15 a month, between the category's cheaper quarter at $10 and its middle at $20, but the page also shows a 100-transaction minimum billed at $300. |
| Free plan and trial | DNo free plan. There's a 14-day trial of Pro or Studio for teams, but it runs on into a yearly commitment: cancel more than 14 days after it ends and you pay half of what's left. | FNo free plan and no trial on record anywhere on its pages. |
| Features | CSend from Acrobat, several signers at once, tracking, audit trails, web forms and branding, plus the PDF tools. But Adobe itself says the signing in Acrobat Standard and Pro doesn't reach the compliance level of Acrobat Sign Solutions, which is sold through sales. | CPKI digital signatures, templates, mass mailer and audit trail. Branding is $499 a year extra, and the API and white labeling are Enterprise. |
| Ease of use | F2.2 from about 650 App Store ratings for the Acrobat Sign app, by far the lowest in this category. You can send from Acrobat on a computer instead, but on a phone this is the app. | CNo store rating on record. Web only, with templates and signer authentication to set up. |
| Platforms and integrations | BWeb, desktop Acrobat and iPhone, with Word, Teams, Salesforce, Workday, Box, Dropbox, Google Drive and OneDrive. No Android app is listed, so it misses an A. | CWeb only, with no integrations listed; the API is for Enterprise. |
| Best for | teams that need Acrobat's PDF tools anyway | banks and title firms that want PKI-sealed signatures |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
