In recent years, there has been many changes related to POS systems. Companies are confronted with increased data protection requirements, changes in VAT regulations, legal standards or various control units, to name just a few. Keeping these requirements up to date in one or more countries at the same time is a huge effort and requires high level of discipline. As a consequence, many companies rely on agencies or partners to implement local regulations on site. This leads to a great effort put into coordination of those large projects to ensure that the same software is available in all regions.
