Zoey supports Customer Specific Products, and product access restrictions for different customer groups.

• For each account, you can specify their Products, which will then be hidden to all other customers.
• You can assign each product to be available to certain customer groups, allowing you to effectively decide what each group can order. If you maintain multiple product lines, or have lines exclusive to certain buyers, this gives you the ability to select who sees them.

Within a given product you can also control things like minimum/maximum quantities and quantity increments.
