I use RightSignature:<p><pre><code> http://rightsignature.com/
</code></pre>
SignSquid charges $9/mo for 10 documents. RightSignature charges $14/mo for unlimited documents.<p>I enjoy the workflow of RightSignature. I upload the doc/PDF of the contract, or import for Google Docs. I find the fields that need to be filled in, highlight them, and designate who fills it in (me or the counterparty).<p>I then fill in text fields using a text entry box and the signature using my mouse. They have a good system for tracking the mouse speed to show the width of the line, and the signatures look quite good with minimal effort.<p>When you want a counterparty to sign, they get an email asking them to follow a link. They then can fill in the fields and sign, without registering for the site. Finally, we both get a PDF of the final contract, and they store the final PDF on their site. You cannot "delete" the contract from their site once it has been executed, which corresponds to the gut feeling that the contract is cannot be undone (without executing a contract that overrides it).<p>I also think their design looks serious and conveys to proper gravity to a contract signing process.
