Is electronic signature legally binding?

Yes! Electronic Signatures are 100% legally binding in nearly every jurisdiction around the globe, including the U.S. and E.U.

Furthermore, electronic signatures are actually MORE difficult to forge than a traditional ink signature, because of the digital “fingerprinting” left at time of signature.

For all paying accounts, expert witnesses are available for court appearance or deposition in the highly unlikely event enforcement assistance is needed.

Either is fine, and there’s no real wrong answer – in the end the result is the same – you need both.

To setup e-signature then payment via paypal, create your form as usual (at ) and on the right side you’ll see some options under “User Flow” like this:

There you can choose an e-commerce product or service to auto-redirect the user after signature for payment. In this example, the user will flow from (1.) Your website, to >>  (2.) the signature page, then >> (3.) payment page, then (4.) back to your site for typically a receipt and thanks message confirming what ......More...
