# Billing

Devin has two pricing models:

* **Self-serve**: Free, Pro, Max, and Teams plans you can sign up for directly at [app.devin.ai](https://app.devin.ai). Self-serve usage is billed through a mix of included quota and on-demand credits. See [Self-serve plans](/admin/billing/self-serve) for full details.
* **Enterprise**: Devin Enterprise customers are billed in Agent Compute Units (ACUs) at the rate set in their order form. See [Enterprise](/admin/billing/enterprise) for how ACU consumption is tracked, or [contact sales](https://devin.ai/contact) for pricing.

For how Devin meters work in general (how usage accrues, idle/sleep behavior, and tips for keeping consumption under control), see [Usage](/admin/billing/usage). The tips on that page apply to both pricing models.
