Which inventory management strategy is useful for managing prices based on purchase quantity?

The inventory management strategy that is useful for managing prices based on purchase quantity is Quantity/Volume Pricing. This approach allows businesses to offer different price points depending on the quantity of items purchased. It incentivizes customers to buy in larger quantities by providing a discount or a lower price per item as the purchase volume increases. This strategy not only aids in managing inventory levels but also helps to boost sales by encouraging bulk purchases.

In the context of business operations, utilizing Quantity/Volume Pricing can lead to reduced order processing costs and improved inventory turnover, as customers are more likely to buy higher quantities to take advantage of the cost savings. This makes it an effective strategy for both inventory management and sales optimization.

On the other hand, the other options do not specifically relate to price adjustments based on the quantity purchased. Standard Pricing involves fixed prices regardless of quantity, Percentage Discounts offer discounts off a price but don't necessarily relate to how many items are bought, while Flat Rate Pricing provides a single price for a product or service, without consideration for the quantity purchased.
