Some risk factors exist within the implementation process of an ERP system in small companies. However, researchers claim different views on which impacts the implementation of ERP systems have. Actually, there are relatively few empirically based ERP implementation studies in small companies and its impact, as most of such studies are focused on larger companies. This paper is based on a case study at a small company. The aim of the paper is to explore risks at a small company when planning to implement an ERP system. The analysis shows that an ERP system is a good solution to avoid using systems that are not integrated. An ERP system could integrate all information in only one system, and all information could easily be accessed within that system. The implementation therefore lead to decreasing costs in the daily work as the activities and processes can be performed more effective and efficient.
