I need a simple contract module that will connect to products in Zoho CRM and that are time bound. I sell annual memberships and want to be able to track the start and end date of a contract (and various dates in between like the halfway point) and I want it all to connect to CRM Contact Records. I also want to create a workflow for these contracts so they can be submitted from my sales person to my sales manager for approval. Upon approval, I want several workflow tasks created related to delivering benefits to the contact whose contract has now been "activated".
