Why SumoSign

Transparent tiers. No hidden fees.

One price, one counter

Flat per organization with no per-seat math. An envelope is an envelope whether it's sent from the dashboard, the API, or your agent — no separate automation cap.

Your agent runs the workflow

Full API, MCP, and llms.txt access on every plan. Give your agent one API key — it prepares, sends, and tracks. Every signature still comes from a real person.

No surprise overages

We publish the envelope numbers and tell you at 80% usage. You choose whether to upgrade — nothing is billed behind your back.

Ready to stop apologizing for your signing experience?

Pick the tier that fits and get set up today. If you need procurement, SSO, or a dedicated rollout, our team will have you configured within one business day.
