OrderCup support strong basic Product details for your store by having  a Product Master table. The Product Master is populated by fetching Product Details from the store, rather it is populated from information on the products in the  existing fetched orders in your OrderCup store.

To build the product table from the current set of orders, go to Settings --> Products  and click the Import Products link. This will initiate a background job to build the Product Master and may take a few minutes.
