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 proposal already carries.
Five seats to start
Oneflow's Business plan starts with five users and is billed annually only. Calisto has no seats and no year to commit to.
Priced options and a deposit
A Calisto proposal carries up to four option tiers, lines from the price book and a deposit collected on the link, with the signature inside the same charge.
Approvals on every proposal
Oneflow's Business plan adds approvers before signing. Calisto holds a proposal at or above your approval amount for review before it is sent, at no extra charge.
Honest answers
Leaving Oneflow
Do my proposals move across?
Sent and signed proposals stay with Oneflow, with their signatures. Export them before you close the account. Templates rebuild in the block editor, and every proposal you send from Calisto keeps its own version history.
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 a proposal cost?
The pricing section on this page reads the live catalogue and is the authority on the figure. A proposal is charged once, when it first reaches your client. The signature, every signer, reminders, re-sends and new versions are inside that charge. Quotes cost nothing.
Is anything charged on top?
Two things, both stated plainly. A government ID check on a signer is its own product, priced per check. A change order signed after the proposal is accepted is its own envelope, charged as Calisto Sign.
What does Oneflow do that Calisto Proposals does not?
The table above says so plainly. AI writing, embedded video, a public API and native CRM connectors are theirs; the deal, the price book and the payment the proposal belongs to are ours.
