It's a app that allows you to create some suppliers and set a markup percentage for each one and select which categories they can add their products to with a login name and password.

The suppliers can then login to their own pages where they can add products to their categories entering the cost price that they sell the product to you for. The front of the shop will show the list price determined by the markup on cost you had set for that supplier.

The suppliers can only see and modify their own products and not any other suppliers.
