Legally compliant with U.S. and international laws

BoldSign is legally compliant with U.S. (ESIGN) and international (eIDAS) eSignature laws.

The final document is also digitally signed so that any tampering in the future can be immediately detected.

A friend recommended BoldSign as a solution comparable to DocuSign but built for SMB use. It’s been easy to use and easy for my customers to use as well. I absolutely recommend BoldSign.

The perfect alternative to DocuSign. BoldSign is the sleek, modern interface. It’s easy to navigate as a first time user and the learning curve is minimal!

BoldSign provides a quick and easy way for me to send forms to my business partners. These forms can be signed on most devices, without an account and for free! The sheer level of ease puts BoldSign ahead of the competition.
