I am looking for a simple Android front end POS system which will run on 15" Touch screen terminals. The system will be based on multiple departments with simple to add products. The system will not require a stock management system. The system will have end of day reports by product, department & payment method. This system will require a simple CMS to allow editing of departments and products with the ability to work when the system is on and offline. Please do not apply if you have not completed a project like this before. Simplicity is key to this project.
