CRM Lite is designed to be a low cost, but powerful solution targeted at smaller companies that do not want to pay $65/seat/month for the full blown Microsoft CRM 2013.
CRM Lite is based on SharePoint and is a great way to get started with CRM in the cloud. It is based on Microsoft Access, a full relational database, that is easier to maintain and modify than Microsoft CRM 2013.
