Create an embedded signing session with pre-filled signature fields and enable or disable signature editing

Pre-filling a signature field with a recipient's name and disabling signature editing is a great way to protect a signed document from unwanted errors or tampering. The signer’s name will appear in the document where they can either confirm their signature or decline the eSignature invite. However, you can also allow signers to edit their signatures if your security policy permits it.

Sign Now - a great value, simple to use

Galen B

What do you like best?

Sign Now was very easy to setup and use. The experience for the customers is also very simple, and it's very easy to add fields. We used this for various types of agreements. Custom agreements were very easy to use, but we mostly used it for sending the same templated contract to all our customers. I also enjoyed that it expired the agreement, which helped our closing rate and assisted in tracking our sales team.
