Software for Online Record of Sales

One of the key elements of retail facilities is a cash register system because it optimizes the checkout process. Even though retail firms usually present a conservative behavior towards innovations, they still need both human resources and high-quality machines to help maintain the smoothness of daily processes, especially with cash registers and POS systems since they carry out the most crucial process in the whole establishment. Law and regulations are also an issue that firms must deal with. Most of cash registers and POS systems in the Czech Republic are to be deemed useless due to the introduction of the new Act of Online Record of Sales. This means that old machines and systems will have to be replaced by newer ones. The goal of this thesis is to design and implement a solution for retail firms to cope with legal requirements of the regulation. To achieve this goal, the thesis first deals with the requirement analysis of POS systems. It also provides a detailed analysis among significant features of the statutory regulation while describing the fundamentals of that regulation. A design of a POS system is then proposed based on gathered information. Its implementation is then carried out using the web as its platform. The POS system implements a client-server model using some of the newest and most popular JavaScript web technologies including jQuery, Express framework, Node.js and MongoDB database system. The output of this work is an on-line application which provides many important features to support retail businesses and thus can become a convenient and beneficial solution for entrepreneurs.
