# How billing works

Quake AI uses **resource-based monthly billing**: you pay a fixed monthly amount for the subscription package and add-ons you choose.

Invoicing and subscription records live in the **Quake AI account portal**.

## Billing cycle

Quake AI issues invoices monthly at the start of each billing period.

## What your bill includes

Your bill includes your **subscription plan** (compute and included resources for that tier) plus **add-ons** you enable, such as extra object storage or additional public IPs.

Each plan includes **unlimited data transfer**; Quake AI does not charge separate egress fees for normal use.

## Guarantees

Named monthly plans include a **30-day money-back guarantee**.
