Possibilities for Functional Improvement of B2B Systems on Serbian Market

B2B systems are still in a state of flux. There are numerous techniques for implementation and even more approaches for theoretical debut and classification. Most of existing solutions have certain functional limitations, depending on market and industry they serve. This paper focuses on the horizontal network marketplaces, as a specific type of B2B systems. The possibilities for improving functionalities of B2B systems and removing limitation factors in development and use are discussed. It further presents existing wide spread solutions and limitations of Serbian market, as an example of environment with a low level of IT readiness. We designed and implemented B2B Web portal "Market4Net" which offers and illustrates possible improvements in the domain. This portal is intended for Serbian market and aims to overcome described difficulties. Our research mainly concentrates on development aspect of B2B, but also touches some issues related to collaboration management and trust building mechanisms.
