Take Inventory: Before you can determine a minimum order quantity, you need to know what your inventory levels are. Take a full inventory of the items you're looking to order and determine how much you have in stock.
Analyze Demand: After you know your inventory levels, analyze how much of the item you’re selling. Look at your sales data to get an idea of what the average demand is for the item and how often you need to replenish your stock.
Set Reorder Point: Use the inventory and demand information to set a reorder point. This is the point at which you will need to replenish your stock.
Calculate Lead Time: Lead time is the amount of time it takes for you to receive your order. Consider how long it typically takes for your supplier to deliver the item and factor in any additional time needed for processing or customization.
Determine Minimum Order Quantity: Once you have all the information, you can determine the minimum order quantity. This is the lowest amount of the item you need to order to restock the item.
