Why it is more expensive to maintain a perpetual inventory system?

Maintaining a perpetual inventory system is more expensive due to the need for advanced technology and software to continuously track inventory levels in real-time. This system often requires significant investment in hardware, such as barcode scanners and RFID systems, as well as ongoing costs for software updates and support. Additionally, regular employee training is necessary to ensure accurate data entry and inventory management practices. These costs can add up, making perpetual inventory systems pricier compared to periodic inventory systems.
