Docshaker.com is an online service for signing agreements online. Docshaker takes your .doc, .docx or .odt files and converts them into online-ready documents for clients to sign with a mouse. It's a flexible system which allows users to prepare templates which can be customised when being sent to clients and also allows multiple inputs from multiple signees.
