Easily collect legally binding eSignatures online from our app or yours. An enterprise-grade electronic signature application and API with all the bells and whistles at an affordable price.
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.
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.
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.
All paid plans include access to all the available features. With BoldSign, you don’t constantly need to upgrade to get access to new features.
Syncfusion, the company behind BoldSign, has been building enterprise-grade software for over 20 years. We are committed to making market-leading electronic signature software.
We promise that you don’t have to deal with hidden document limits, feature limitations, or unexpected overage charges.
We strive to provide the best possible customer support experience and are always ready to assist in any way we can, even if you are on a free plan.
