# Supported overage models

Stigg supports flexible overage pricing models that can be billed independently from the base subscription cycle (e.g., monthly overages for annual subscriptions). The supported models include:

* **Per unit**: Charges a fixed price for each additional unit consumed. Example: \$0.01 per additional unit.
* **Per block**: Charges a fixed price for a predefined block of units. Example: \$1.00 for every block of 1,000 units.
