What Nusii prices separately, beside what a Calisto proposal already carries.
Users by the plan
Nusii plans include one, three or five users, and each extra user is charged every month. Calisto has no users to count; anyone in the account sends.
Active proposal limits
Plans cap active proposals at 5, 20 or 50 and above. Calisto has no cap; each proposal is charged once, when it reaches the client.
Payments above the entry plan
Payments and CRM integrations start on the Agency plan. A Calisto proposal collects a deposit on the link through the gateway the account already uses.

Leaving Nusii
Sent and signed proposals stay with Nusii, 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.
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.
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.
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.
The table above says so plainly. Automatic reminders, your own domain, a public API and native CRM connectors are theirs; the deal, the price book and the payment the proposal belongs to are ours.
