Send your first document for signing in less than 5 minutes

We have invested a lot of effort to ensure that BoldSign is an intuitive and easy-to-use app despite offering tons of functionality. The only way to truly experience this would be to sign up for a free account and send a few signature requests yourself.

Fast and scalable api
Seamlessly integrate eSignatures into your apps

We offer a comprehensive REST API that lets you initiate, track, and fulfill signature requests from within your own applications. Our APIs have been built from the ground up to be scalable to easily handle millions of documents when required.

Code Window

Collect signatures from multiple people with just one link.

Embed signature URLs on your website or send secure URLs via email to multiple signers. This is perfect for getting documents like account applications, event registrations, and NDAs signed. No coding required: a user-friendly interface. A great alternative to DocuSign’s PowerForms. Start collecting signatures quickly!

Legally Binding

Legally compliant with U.S. and international laws

BoldSign is legally compliant with U.S. (ESIGN) and international (eIDAS) eSignature laws. We record all major activities that happen during the signing process and provide a downloadable copy of the complete audit trail report. The final document is also digitally signed so that any tampering in the future can be immediately detected.
