Cartage.com now leads directly to Docusign.com. We have used Docusign since almost Day 1 - and still enjoy a "grandfathered" rate for our account. As another reviewer stated "I did not know about this - CARTAVI.COM is nothing but DOCUSIGN.COM! And glad that I know about it now. (Just used cartavi.com - and landed up on my account of DocuSign.com.) Now should I say that DocuSign is one of the leaders when it comes to Online Electronic Signatures - and they have maintained that leadership by providing us with one of the best product, easy to manage not only for us but also for our clients? In a nutshell - CARTAVI is nothing but DOCUSIGN at the time of writing this review - and yes, one of the most essential product for our business it is."
