Your whole team, one flat price. Pro is $35 a month for the whole workspace: no per-seat fees, unlimited people and documents. Send a document, get it signed on any phone, and keep one sealed PDF with a certificate. Signers can pay while they sign, straight into your own Stripe account, and Pro adds no fee. Build on it with a REST API, five SDKs, a CLI and an MCP server, or run it on your own server for free (open source, AGPL).
