I'm new to ZohoCRM and want to use it for a B2C Company.

My process flow is -> get order from website / partners, create invoice and ship goods -> keep track of customers with emailers, phone calls, etc -> keep track of which partner is giving how much business

I followed the steps in the help section and disabled account from everywhere.

Now when I received an order, I made a new contact and filled in the name, address, Partner (custom field).

Then I went to invoice and created an invoice (for products which I have already added). However this invoice doesn't have the address pre populated and I need to re enter it. This is redundant work for me. 

Is there a way out?

Is there a better way of doing these things?

Second question: How can I track which partner has given how much business.
