# Request invoice / payment

## Overview

Send invoices by email to your customers, and request payment for your products. The email sent to your customers will have a link to a checkout page where the customer can make a payment to you. The **Request invoice/payment** functionality exists primarily for invoicing purposes where it may be necessary to bill for a product or service that does not have a static price, or the final sales price is unknown.

You can also use **Request invoice/payment** for billing excess server time for web hosts, or for services that need to be billed in addition to the product/pricing structure hard-coded via 2Checkout’s product listing.

## Reporting

You can track orders placed as a result of the Request invoice flow from **Orders & customers** > **Order search**. Filter the results by using the External reference included in the email sent to your customers. Alternatively, you can export the orders in full options template format, and check for the values in the External Reference No column.

Measure the performance of your Request invoice feature by accessing the [Email Metrics report](https://secure.2checkout.com/cpanel/email_metrics_report.php) available in the Control Panel. The information extracted in the report can be split based on the ordering flow used: ConvertPlus or Default 2Checkout flows.
