The TransERP system is being implemented at MZK in Ostrołęka. In order to improve training and practical learning of the system for users, we have launched an additional test environment that will enable independent test work without the risk of entering incorrect data in the already partially launched production version of the system. TRANS ERP is a comprehensive, integrated IT system supporting all areas of the Public Transport Company’s operations. It was designed and developed as a dedicated solution supporting the management of a public transport company.
