While both volume pricing and tiered pricing aim to incentivize customers, their structures are distinct. Scale pricing is straightforward: the more units you buy, the less you pay per unit. It's a direct correlation between quantity purchased and the per-unit price. On the other hand, tiered pricing operates within specific brackets or tiers. For example, purchasing 1-10 units might cost $10 each, but 11-20 units could be priced at $9 each. It's less about the total quantity and more about the specific range or tier the purchase falls into. This system can often be seen in service-based industries, like utilities or software services, where users are charged based on predefined usage tiers.
