Reorder frequency is the number of times you place an order with your supplier within a certain period, and it can have a major impact on your inventory costs, cash flow, and customer satisfaction. To find the best option for your business, you need to evaluate your reorder frequency. There are various strategies you can use for this, such as economic order quantity (EOQ), fixed order quantity (FOQ), fixed order interval (FOI), and vendor-managed inventory (VMI). With EOQ, you will be determining the optimal order size that minimizes your total inventory costs, including ordering costs and holding costs. FOQ involves setting a constant order size that is placed whenever your inventory level reaches the reorder point. FOI is a regular time interval between orders regardless of your inventory level. Lastly, VMI is a collaborative arrangement where your supplier monitors your inventory level and replenishes it as needed.
