Lagerhantering och Ombeställningar
The Reorder Point (ROP) is the inventory level at which you should place a new order with your supplier. It ensures you always have enough stock to meet customer demand while your new shipment is in transit.
Formeln:
Your reorder point formula is simple: (Average Daily Usage x Lead Time) + Safety Stock. This prevents stockouts while minimizing holding costs.
Safety Stock is extra inventory to buffer against unexpected demand spikes or supplier delays. Retailers typically use 10-25% for fast-moving items and 20-50% for items with unpredictable demand.
💡 💡 Pro Tips: Adjust safety buffer seasonally. Increase it before busy seasons (holiday, back-to-school) and decrease during slow periods.
