Hi Karthik,
I think it would be best if we got in contact directly to discuss your exact requirements.
In terms of licensing and technology, junariCRM is open source software under the terms of the AGPL and is built on the
OpenERP OpenObject framework.
Please send me a PM with a contact number/email so that I can arrange a full demonstration of junariCRM and discussion of the other features in which you are interested.
