Everything you need

Built for teams that sign a lot of things

From first draft to countersigned PDF, Proposo covers the entire proposal lifecycle — in one open-source, self-hostable platform.

Beautiful editor

A modern drag-and-drop editor that feels like Notion. Blocks, tables, pricing, images — everything you need to write a killer proposal.

Track every click

Know the second your proposal is opened, scrolled, and signed. Real-time notifications keep you in the loop.

Legally binding e-signatures

Full audit trail, tamper-proof hashes, timestamp authority support. Meets eIDAS, ESIGN, and UETA requirements.

Templates & workflows

Create reusable templates for your team. Automate approval chains, countersignatures, and follow-ups.

Self-hostable

Run it on your own infrastructure. Your data stays yours — no third-party processors, no surprises.

Open source

MIT-licensed and built in public. Fork it, extend it, audit it — or use our hosted service.
