„Last year we started preparing to implement a brand new release of an e-commerce system in cooperation with Rossum & Hamilton team. This implementation was based on our experience with previous versions of the system and it reflected the needs of the Czech Army and the Czech Republic regarding transparent and nondiscriminatory electronic trading. The resulting product fully meets our needs and allows us to further automate the conducting of safe and transparent tendering for our resort. Cooperation with Rossum & Hamilton was excellent on both professional and personal level and the performance of the project team was flawless. The experience from the project is a solid foundation for cooperation on further development of the system.“
