Hello!

I'm a bit new to the ZOHO CRM. I have got a small ecommerce (store). I need to use just a few modules of Zoho CRM. Main tasks:

1)One module in which all my customer data will be stored. It will be synchronized from my Magento.

2)Second module with orders (Sales orders module)

I tryed to use Leads module, but it does not have an option to add Sales Orders as the RELATED LIST.  I have tried to create my own personal module and the same issue , it does now allow to add Saled Orders as a RELATED LIST.

Which module can be customized so that I would be able to  open customer data and see his orders on one page?
