Lemon is an open source point of sale for linux and other unix systems. It is targeted for the small and medium sized business, and has been conceived for ease of use and customization.

It allows to change the look by editing a CSS file and making personalized images. This, to provide a modern good-looking interface to impact the user and the client that looks at it.

It is considered a general point of sale, not focused to a specific sector. It can be used at a general store, a fast-food restaurant or a book store.

These are some features:

• Tested with a parallel port ticket printer
• It must work with a barcode scanner
• It is probably that works with touch screens
• It supports product photos
• It has a grid view
• It has a separate editor for the database tables (products,users,clients...)
• It is translated to Spanish, French and Chinese (simplified).

Lemon depends on qt4 and kde4, so you must install kde4.
