# Customer portal

> Let customers view and pay their invoices online — no account needed.

The **customer portal** is a self-service page where your customers can view and
pay their [invoices](/guides/sales-customers/invoices) online. They don't need a
TillBiz account — they open a secure link you send them.

## What customers can do

* **View invoices** sent to them, with your branding.
* **Pay online** — for example via M-Pesa where enabled.
* **See their history** of invoices and payments.
* **Reach support** if your business offers it.

## How it works

<Steps>
  <Step title="You send an invoice">
    When you [send an invoice](/guides/sales-customers/invoices) by email, it
    includes a secure link to the portal.
  </Step>

  <Step title="The customer opens the link">
    No sign-up required — the link gives them access to that invoice.
  </Step>

  <Step title="They pay">
    The customer pays online, and the invoice updates to **Paid** automatically.
  </Step>
</Steps>

<Tip>
  Because payment status updates automatically, the portal cuts down on the
  "have you received my payment?" back-and-forth and keeps your invoice list
  accurate.
</Tip>

<Warning>
  Portal links are tied to specific invoices and customers. Remind customers not to
  forward their links to others.
