Instead of 'orders' there will be worked with 'quotations'
Also there must be some extra in admin, like;
*Quantity in stock per article (so automatically when admin approave order, than in stock you see the changes)
*Possibility to give client restrictions on quantity of orders orders
*must see all debt people
*all orders that are not paid yet, which people, more open by this client?
So all features, that are needed for businesses
