This paper presents a combined method for selecting ERP systems, integrating BPR efficiency, reducing IS payroll, considering international differences, and using the PIRCS meta-method for smart multicriteria selection. Various criteria, such as cost, functionality, support, and flexibility, are analyzed to aid in decision-making. The study also explores the benefits of open-source ERP software and outlines the steps involved in the selection process.
