## How to choose a e-signature tool

* Choose Docusign when the other side expects it, or you need agreement management, ID verification and enterprise compliance. Watch the envelope caps: Standard and Business Pro include 100 per user per year.
* Choose Dropbox Sign for unlimited signature requests on a flat per-user plan, or a well-documented API for sending documents from your app.
* Choose Documenso for an open-source tool with a free hosted plan and flat team pricing, or to keep signed documents on your own servers.
* Choose DocuSeal to embed a signing form inside your own product: its open-source edition is free to self-host, and the API costs $0.20 per signed document.
* Count documents, not seats. A team that sends a few hundred contracts a year can outgrow Docusign's caps long before it needs another user.
