When deciding on an inventory model for your import/export business, you must consider the nature of your products, your market, and your suppliers. Just-in-time (JIT) is an option that can minimize inventory costs and risks, but it requires reliable suppliers, accurate demand forecasting, and efficient logistics. Alternatively, economic order quantity (EOQ) is a model that calculates the optimal order quantity to minimize total cost of ordering and holding inventory. This model necessitates consistent demand, stable prices, and low order lead times. Safety stock is another option that keeps a buffer of extra inventory to prevent stockouts due to unexpected demand or supply fluctuations. This model requires careful inventory tracking, regular replenishment, and adequate storage space. Ultimately, you should choose the inventory model that suits your business goals, budget, and capabilities and review it periodically to ensure its effectiveness.
