# Customer Portal

The Customer Portal is a hosted self-service interface for customers to manage their billing. Customers can view and download invoices, update payment methods, track subscriptions, and manage account information—reducing support overhead for your team.

## Access Methods

* **Dashboard links**: Direct links generated from the Measure dashboard
* **API access**: Dynamically generated authenticated links via the [Customer Portal API](/api-references/customer-dashboards/get-customer-portal-link) for embedding in your application
* **Magic links**: Company-level portal access that customers retrieve using their email on file

## Customization

* **Branding**: Custom theming to match your brand
* **Content**: Selectable billing sections (invoices, subscriptions, payments, credits)

## Self-Service Subscription Management

* **Cancellation**: Customers can cancel subscriptions, effective at the end of the current billing term
* **Seat/license upgrades**: Immediate effect with prorated charges for the remainder of the billing period
* **Seat/license downgrades**: Takes effect at the start of the next billing cycle with no proration

Seat and license management is available for license-based and seat-based subscriptions only.
