## What is Billing & Payment?

Billing & Payment is the center for interacting with all product/service branches within the scope of GreenNode Service, including **vServer, vStorage, vMonitor, vCloudcam, vCDN, and others**.

Here, we will focus on handling business regulations that directly affect customers' financial management, such as **Payment orders, Creating product invoices, Recording resource usage information (configuration changes), and Automatic invoice payments**.

The benefits of integrating the Billing & Payment system within the scope of using GreenNode Service are:

* Providing uniformity in the user experience within the scope of GreenNode Service products.
* Concentrating on customers' financial-related data when using the service helps minimize data discrepancies and easily reconcile data.
* Easy and quick integration provides a full set of Billing & Payment features when deploying new product lines.
* Providing accurate and intuitive analysis data at the GreenNode Service level, helping customers have an overview and develop appropriate.
