mutual funds through a demat is more wiser than through regular broker ?

Hi,

During my financial planning, i was advised to achieve my long term goals through SIPs in mutual funds.

Now currently i am doing my SIPs through FundsIndia. But the planner suggested to do it through a demat account for long term instead of platforms like FundsIndia. Also i dont do trading in shares so the demat account will be only used for mutual funds SIP.

I have a HDFC Savings account, so if at all it is advisable to prefer demat account for sips then i will consider it through HDFC.

So should i consider to switch over from FundsIndia to Demat Account for my mutual funds SIPs, with keeping factors like cost , security and others in mind .

Please list thee factors based on which it easy to decide over it .

Thanks,

Hitesh
