WHAT A SEAT DOES NOT COVER
The seat is the start of the bill, not the end of it.
What Oneflow prices separately, beside what a Calisto envelope already carries.
Five seats to start
Oneflow's Business plan starts at five users and is billed annually only. A Calisto envelope is charged once, when it is sent, whoever sent it.
eID and SMS signing cost extra
eID and SMS signatures are marked as paid extras. In Calisto, identity is its own per-check product, switched on per document.
A contract platform around the signature
Oneflow sells contract management with signing inside it. Calisto Sign is the signature on its own, next to Docs and Proposals, each priced by what it does.
Honest answers
Leaving Oneflow
Do my signed documents move across?
Completed documents generally stay with Oneflow, 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.
Can I bring my templates?
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.
Can I get out of my current contract?
Upload the contract from the offer above. We read the term, the fees and the notice period, and hold what leaving costs you as credit in your Calisto wallet. Cancel, show us the proof, and it is released. A person reviews some claims, such as a contract in another currency.
What does an envelope cost?
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.
What does Oneflow do that Calisto Sign does not?
The table above says so plainly. National eID signing, a developer API and native CRM connectors are theirs; the record the signature belongs to is ours.
