MRP One vs Siemens Opcenter

MRP One is a cloud MRP II platform for manufacturers, covering production planning, materials, workloads and shop-floor operations. Its MRP engine calculates purchasing requirements from bills of materials, sales orders, inventory and supplier lead times. Planning tools include AI-assisted demand forecasting, automatic and manual scheduling, Gantt charts, conflict detection and capacity alerts. Inventory management shows stock levels and reservations, allocates materials, flags shortages and tracks stock movements. Workers can report labor, machine time, scrap and quality data using barcode scanning or touchscreen input. MRP One lists metalworking and fabrication, furniture and woodworking, electronics and assembly, textiles and apparel, and custom manufacturing as target industries. It runs entirely in the cloud, without installation or on-premises deployment. Enterprise plans include custom API integrations; other customers can discuss integration needs with the company. The free plan is limited to one user, 12 workcenters, 15 workers, 25 active orders and a 1 GB database. Small Teams costs €115 a month, while Growing Teams costs €175 a month.
