The users can choose the models, materials and accessories, set the desired dimensions and see the calculated prices immediately. Alongside there is a real time drawing of the configured objects.
The visitors add the items to their shopping cart and build an offer themselves. All shopping cart items and the contact data are then accessible and editable by the employees of the company.
The administrative area provides a full control of the site content but it also manages the full process—offers, orders, deliveries, logistics, installation, invoicing, payments, and more. - Bent Fishinghttp://www.bent-fishing.com/
Bent Fishing is website where the users can browse and search for fishing-related items. The shopping cart can be transformed into an order.

Additionally, it is possible to find all the direct connections between two stops and see a combined schedule of all lines that connect the stops.
The administrators can manage the existing lines, stops, routes, and import the schedules from the GPS data provider.
