# How do invoices work?

## Overview

2Checkout sends PDF invoices via email to both business customers and shoppers after finalizing payment (when the order's status switches to **Finished**).

{% hint style="danger" %}
**Important!** The system sends Purchase Order invoices immediately after you've confirmed the Purchase Orders, before the order's status switches to **Finished**.
{% endhint %}

## Customizing invoices

We offer the possibility of customizing the invoices sent to your shoppers via our Professional Services team. Depending on your needs, we can help you customize details such as additional order and product fields, to better suit your preferences and offer relevant information to your shoppers.

## Availability

The invoice customization service is available only to eligible accounts.

For any kind of invoice customization requests, feel free to contact us.
