Please add Zoho Sign to your evaluation list. We have a Free plan - 5 documents/month and our API plan is charged per document/signature.

We also offer unlimited document signing, tighter integrations, and a reliable technical assistance for all our users.

While selecting an e-sign app, users should consider legality of the app's signature and how it complies with their local laws. The market is also overcrowded with over 200+ e-sign apps and decision-makers prefer the most popular ones for these reasons: legality, ease-of use, technical support, scalability, security and privacy.

We are just four years into this e-sign space and companies both small and big are loving Zoho Sign. Give us a try. DM for any help.
