# Carts and Checkout

A cart is a virtual shopping basket that customers can use to pick products they want to purchase. Checkout is the process of the customer placing an order. This overview introduces the available features related to carts and checkout.

## Features

### Cart Management

Customers can manage their cart including adding, updating, and removing items from the cart.

  {
    type: 'link',
    href: '/modules/carts-and-checkout/storefront/implement-cart',
    label: 'Storefront: Implement Cart',
    customProps: {
      icon: Icons['academic-cap-solid'],

    customProps: {

    }
  },
]} />

### Shipping and Payment

Developers can integrate any third-party provider or custom logic to offer shipping and payment options for customers during checkout. They can integrate them using existing plugins or by creating their own.

Admins can specify available shipping and payment processors during checkout for customers based on their [Region](../regions-and-currencies/overview.mdx).
