Stairstep pricing

Stairstep pricing uses a series of predetermined "steps" or thresholds at which the price of the product or service increases. The customer does not pay per unit, but one price for the entire range their usage falls in.

Unit-based example

An example could be the following schedule:

Tier Number	Lower bound	Upper bound	Price
1	0	≤ 100	25.00 EUR
2	> 100	≤ 1000	20.00 EUR
3	> 1000	∞	15.00 EUR

A customer pays a fixed price for the entire range. Using the example usage of 200 GB, the customer would pay 25.00 EUR + 20.00 EUR = 45.00 EUR.

Amount-based example

Stairstep pricing is the only pricing type where the pricing is not percentage-based, but an amount itself.

The tiers are still based on monetary amount values, but the price per step is also a full amount. In the below example, a customer that processed $43K reimbursed transactions will pay $100 + $80 = $180 for that billing period.
