# Subscriptions Overview

> Accept recurring USDC payments using spend permissions on Base

Defined in the [Coinbase Wallet SDK](https://github.com/base/account-sdk)

<Info>
  Base Subscriptions enable recurring USDC payments. Users grant your application permission to charge their account periodically, eliminating the need for manual approvals on each payment. **No fees for merchants or users.**
</Info>

## How Subscriptions Work

<Steps>
  <Step title="User Creates Subscription">
    User approves a spend permission for your application to charge a specific amount periodically.
  </Step>

  <Step title="Application Charges Periodically">
    Your backend charges the subscription when payment is due, up to the permitted amount per period.
  </Step>

  <Step title="Automatic Period Reset">
    The spending limit resets automatically at the start of each new period.
  </Step>

  <Step title="User Can Cancel Anytime">
    Users maintain full control and can revoke the permission at any time.
  </Step>
</Steps>
