POS Systems: Integrating IoT inventory management with Point of Sale (POS) systems automates the updating of inventory levels based on real-time sales data. When a sale is made, the POS system communicates with the IoT inventory system to adjust stock levels instantly. This integration ensures that inventory records reflect the latest sales activity, reducing discrepancies and providing a more accurate overview of stock usage. It also helps in maintaining optimal inventory levels, minimising stockouts and overstock situations.
Kitchen Display Systems (KDS): Connecting IoT systems with Kitchen Display Systems (KDS) enhances kitchen operations by synchronising inventory data with order processing. As orders are placed and processed, the KDS updates the inventory levels in real-time, ensuring that the kitchen staff is always aware of the available stock. This integration helps prevent situations where ingredients are unexpectedly unavailable during peak service times, leading to smoother operations and better customer satisfaction.
Supply Chain Management Software: IoT inventory systems can be integrated with supply chain management software to refine forecasting and ordering processes. By sharing real-time inventory data with these tools, restaurants can improve demand forecasting and make more informed ordering decisions. This integration supports efficient replenishment of stock, reduces the risk of over-ordering or under-ordering, and enhances overall supply chain efficiency. It also allows for better coordination with suppliers, leading to more accurate and timely deliveries.
Benefits of IoT-Enabled Inventory Management
Reduced Food Waste
IoT systems significantly reduce food waste by providing real-time data on inventory levels and expiration dates. For example, if sensors detect that certain items are nearing their expiration date, the system can alert staff to use these items before they spoil. This proactive approach minimises waste and maximises the use of purchased goods.
Optimised Inventory Levels
Accurate tracking of inventory levels allows restaurants to maintain optimal stock levels. By analysing usage patterns and predicting future needs, IoT systems help prevent both overstocking and stockouts.
