Help!

Hello everyone:

I'm using the POS Odoo, but I have that encontrato Reports / sales detail. I print daily sales but margins by product.

There is a module Margin per product, or have installed, but this does not make me calculate if I'm not going to Point of Sale / Ordering and billed orders.

But as you know, for every sale made at the POS order is generated, imagine selling products a day hundred, hundred orders have to check!

Is there another way to get the margins?

Or at least a way to link all sales of POS to a single order?

I really appreciate your help this already has me desperate, I turn here, because I'm tired and seek a solution to this.

Thank you
