If your office is going paperless, one of the things you'll need to deal with is how to handle documents, such as contracts, that need to be signed. The good news is that electronic signatures can now be easily handled over the Internet.
One of the products we highly recommend is EchoSign - www.EchoSign.com. Using EchoSign, you can upload an electronic document (Microsoft Word, PDF, etc) or fax in the document if you only have a paper copy. Next, you enter the recipients signature with a note and then just hit "send". The application handles the collection and storage of the signature so you don't have to store everything on site.
Electronic signatures have generally been legally recognized around the world for many years. The Electronic Signatures in Global and National Commerce Act(E-Signature Act") became effective in the US on October 1, 2000. Since then, online electronic signatures on commercial transactions and most other agreements have an equal legal status to a written signature.
EchoSign can be integrated with Salesforce.com and its currently used by over 3,000,000 businesses and business people.
