# Customer Service Overview

## Overview

The Customer Service enables you to create and manage customer profiles at payment processors using the Java SDK. Storing customer details with connectors streamlines future transactions and improves authorization rates.

**Business Use Cases:**

* **E-commerce accounts** - Save customer profiles for faster checkout on return visits
* **SaaS platforms** - Associate customers with subscription payments and billing histories
* **Recurring billing** - Link customers to stored payment methods for automated billing
* **Fraud prevention** - Consistent customer identity improves risk scoring accuracy
