The position of small and medium-sized enterprises in Zala County develops peculiar to the situation in Hungary. The location of the county is not bad because there are five capitals within a radius of 250 kilometres. This central position and the small distances is much appreciated in logistics, especially in the case of local companies. The above fact also has a significant impact on the logistics processes of SMEs, many of which are closely linked to these companies, either as suppliers or as service providers. The county administration is aware of these favourable qualities, and in recent years significant developments have begun in the county council. Our entire research is related to micro-, small- and medium-sized enterprises in Zala County, especially service providers. Our research explores and models the logistics processes connected to the service providers. The analysis is performed with a generalised simulation model. In the framework of our study, we attempt to find the bottleneck to make the previously mentioned processes more efficient. The article also includes a literature review of the modelling of the problem and the logistics processes related to service provider companies. We are also going to present the results of the database-processing related to the topic. In conclusion, we wish to show how service companies have evolved in the local context and how the management of their logistics operations has changed.
