My friend owns a business delivering real-estate flyers around the bay area. He needed a web application to take orders (both from his customers as well as his employees on behalf of customers) and manage those orders. The site was written in Rails and is completely custom based on his business goals.

It provides a modest public facing side for customers to place orders, get product information and contact the business. The ordering process is more complicated than the traditional shopping cart because of the various options a customer has in selecting a product. Credit card transactions are handled through Authorize.net.

There is also an administrative side, in which authorized users can view and edit customers, orders, products and services. All information you see on the public facing side is editable through the administrative interface, such as the FAQ, prices and product descriptions.

The site can be viewed here.
