What Adobe Acrobat Sign prices separately, beside what a Calisto envelope already carries.
The Acrobat seat
Signing comes with an Acrobat licence, so the seat price includes a PDF suite whether the sender needed one or not. A Calisto envelope is priced as an envelope.
The 150th transaction
Team plans cap sending at 150 transactions per user per year. On Calisto there is no cap; the busy month costs exactly its envelopes.
Identity and SMS
Government ID verification and SMS delivery are priced on top. In Calisto, identity is its own per-check product, switched on per document.
Calisto Sign is priced per envelope. Never per seat.

Leaving Adobe Acrobat Sign
Completed envelopes generally stay with Adobe Acrobat Sign, because their certificates are theirs. Download them before you close the account; anything you send from Calisto Sign carries its own certificate and audit trail.
Templates rebuild with drag-and-drop field placement on the PDF you already have. Field positions are in PDF points, so a template you place once is exact on every send.
Upload the contract from the offer above. We read the term, the fee and the notice period, and what leaving costs you is held as credit in your Calisto wallet, released once you show us it is cancelled.
The pricing section on this page reads the live catalogue and is the authority on the figure. One envelope holds every document and every signer the agreement needs, and is charged once, when it is sent; drafting and placing fields cost nothing.
The table above says so plainly. Qualified electronic signatures, a developer API and native connectors to third-party CRMs are theirs; the record the signature belongs to is ours.
