Most of the surprise in an e-signature invoice comes from a few mechanics rather than from the headline price. They are worth understanding before you compare any two quotes, including ours.
Adobe Sign pricing: you buy Acrobat, and signing comes with it.
On the self-serve side there is no standalone Sign plan. E-signing is bundled into the Acrobat for teams plans, priced per licence: Acrobat Standard for teams at US$16.99, Acrobat Pro for teams at US$23.99 and Acrobat Studio for teams at US$29.99 per licence per month, on an annual term billed monthly. A free trial covers up to 10 licences.
Pro for teams is the realistic floor.
Bulk send, web forms, Braintree payments and the Microsoft and Box e-signature integrations start with Acrobat Pro for teams. Standard for teams has none of them. Compare the plan you would actually run, not the lowest price on the page.
Volume is not the problem.
Adobe states there are no usage caps on the Acrobat for teams plans, so you can collect an unlimited number of e-signatures. Unlike envelope or invite allowances elsewhere, the bill grows with licences, not with documents.
The enterprise features are quoted, not listed.
CRM integrations such as Salesforce, Microsoft Dynamics 365 and Zoho CRM, the API, advanced signer authentication and the compliance portfolio belong to Acrobat Sign Solutions, which has no public price and is licensed per user or per transaction. Adobe itself notes that the e-signature capabilities in Acrobat Standard and Pro do not offer the same level of compliance as Sign Solutions.
AI is a separate line item.
Adobe’s contract intelligence comes with the Acrobat AI Assistant, an add-on that Adobe listed at US$4.99 per month for individual customers, and it is included in Acrobat Studio for teams. Pro for teams does not include it.
What to ask for in writing.
Ask any vendor on your shortlist for the same three numbers: the total annual cost at your real document volume, what happens when you exceed the allowance, and what the second and third year look like after any first-year discount. Those three answers reorder most shortlists more than any feature table does.
