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 SigniFlow if
- Fits if you want signing wired into Microsoft 365 and workflows
- Makes sense if you must keep documents on your own servers
Look elsewhere if
- Tight if you stay on SignFree, which stops at 1 user, 3 workflows and 50 documents
- Pricey if you need biometric checks or QES certificates, both marked as extra cost
- Skip it if you want a private tenant price, as those are quoted on request
- Watch out: the page does not say if the $15 price is available monthly, and the trial length is not stated
How we grade them
| 1.6GPAAdobe Acrobat SignWeak | 2.2GPASigniFlowFair | |
|---|---|---|
| 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. | CBusiness Cloud is $15 per user a month, above the cheaper quarter at $10 and under the middle at $20. |
| 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. | CSignFree gives 1 user, 3 workflows and 50 documents of storage, plus a free trial of unstated length. |
| 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. | CWorkflows, a forms designer, digital signatures and Microsoft 365 connectors. Facial liveness, AES and QES certificates and 2FA are extra-cost items. |
| 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. Forms and workflows have to be built, and private tenants are configured. |
| 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. | BWeb, with Microsoft 365, SharePoint, Okta, Microsoft AD and LDAP connections and a full API on private tenants. |
| Best for | teams that need Acrobat's PDF tools anyway | workflow signing with a cloud or self-hosted option |

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.
