Need Input from YOU - My Zoho CRM - eCOMMERCE Colleagues re How You Process Your Orders Within Zoho CRM

Any input from you would be most helpful on this 1 question:  How do YOU process your online orders?

We do not invoice customers.  ALL of orders are paid up front.  Both the customer and me are notified by email when a new order comes in.  Our shopping cart software generates an order number with each new order.

How do YOU process your online orders?

How do YOU know which orders have:

1.  been received by your suppliers confirmation,
2.  been shipped
3.  been paid

ANY "process" information you can provide to me would be most helpful.  

THANK YOU!!
