What kind of documents are supported?

You can use DocuSign to sign any kind of document: .doc, .docx, .pdf, .xls, .xlsx, .txt… anything. DocuSign works with your documents, and is integrated into many of the tools you already use like salesforce.com, Box.net and mobile platforms like the Apple iPhone and iPad.  If you have global customers, DocuSign offers browser-aware localization in the world's most common languages covering 66% of the global population to make it even easier and faster to conduct business beyond the more than 50 countries where DocuSign has already been used to securely sign legally-binding documents.  DocuSign fits in and helps you close business faster.
