# Customer Portal

> Provide customers secure access to view and download their invoices

The customer portal provides a secure and streamlined way for customers to access their invoices in one place. Instead of managing multiple emails or logins, customers receive a single-use, one-time access key that grants them entry to their personalized portal.

## What customers can do

Within the portal, customers can view and download all issued invoices associated with their account, including the following details: invoice status (paid, pending, or overdue) and due dates.

## Enabling the customer portal

To include a customer portal link in invoices:

1. Navigate to **Settings** > **Invoice Preferences**
2. Locate the **Customer Access** section
3. Enable the option to include a link to the customer portal in the invoice

When enabled, customers will receive a portal access link with each invoice, allowing them to check invoice status and view related usage information.

## How it works

When a customer receives an invoice with a portal link:

1. They click the unique, one-time access link
2. The portal authenticates them automatically without requiring a password
3. They land on their personalized invoice dashboard
4. They can view all invoices, check statuses, and download PDFs

## Security

The customer portal uses single-use access keys for security:

* Each link is unique and time-limited
* No passwords or account creation required
* Access is automatically scoped to the customer's invoices only
* Links expire after use or after a set time period
