# Overview

A **Customer** in Flexprice represents a business or individual that subscribes to your plans and is billed for usage. Each customer is uniquely identified and can be assigned to specific pricing plans and entitlements.

**Why Manage Customers in Flexprice?**

* **Track subscriptions**: Associate customers with specific plans and features.

* **Automate billing**: Generate invoices based on usage.

* **Manage entitlements**: Control feature access at an individual level.

* **Analyze usage**: Monitor consumption for better insights.

Customers can be created manually in the dashboard or through API calls for automation.

To configure **Customer Hierarchy** on a subscription (for example consolidated billing across subsidiaries, or a delegated payer who pays on behalf of another customer), see [Customer Hierarchy](/docs/subscriptions/customer-hierarchy). That guide also explains how **usage, analytics, wallet balance, and invoices** behave in **consolidated** (inherited) setups versus **delegated payer**, including why child customers may show no usage in usage-summary APIs and how to use analytics with `include_children` for parent-level rollups.
