# Billing & Invoices

> How engagement and Monitoring Retainer invoices appear and get paid in your portal

Invoices for your engagement and any Monitoring Retainer are delivered through your portal rather than a separate billing system. The **Invoices** page shows every invoice your assessor has issued to your organization.

## What you'll see

Each invoice shows:

* A short description of what it's for
* **Status** — Open, Paid, Void, Uncollectible, or Past due (shown automatically once an open invoice passes its due date)
* **Amount**, invoice number, and the date it was **issued**
* **Due date** (for open invoices) or **paid date** (for paid invoices)

## Paying an invoice

When an invoice is open, a **Pay** button takes you to a secure, hosted payment page to pay online. Invoices that are void, uncollectible, or already paid don't show a pay link.

<Note>
  Not every organization has invoices to pay through the portal today — some engagements are still invoiced and paid through other arrangements agreed with your assessor. If you're unsure how your engagement is billed, contact your Ayliea engagement lead.

## No invoices yet?

If nothing has been issued to your organization yet, the page shows an empty state: your assessor will send invoices here, and you'll be able to pay online as soon as one is issued.
