I would like to know what do you recommend in terms of stock management and stock valuation if you run multiple store / point of sales in odoo. 

Let's say I have a store in Paris and a store in New York, both of them receive product from the main warehouse based somewhere in France.  

Do I want to create one warehouse for each store  and one main warehouse ?

Or 

Do I want to have one main warehouse and create a specific location for each?

what do you think is the best way to manage it ?

Also in terms of stock valuation it seems like I can only see the valuation of my global stock but can't see it for every warehouses

?

Thanks a lot,
