We've extended the tiered and volume pricing models to allow charging customers a flat fee for every usage tier.

With this change you can charge customers a flat fee, per unit fee or combination of both in each tier.

For example, you can now charge customers a flat $200 fee for the first 20 units, then $5 for every unit in the 21-50 tier, and $500 + 3$ per unit from the 51st unit and upwards.
