# Invoices

> Create, send, and track invoices — standalone or from an existing order.

**Invoices** let you bill customers who pay later, rather than settling at the
till. Create an invoice, send it, and track it through to **paid**.

<Note>
  Invoices are part of the **Invoices** feature. If it's not in your sidebar, your
  plan may not include it — see
  [Subscription & licensing](/guides/billing-addons/subscription-and-licensing).
</Note>

## Create an invoice

<Steps>
  <Step title="Open Invoices">
    Select **Invoices** from the sidebar.
  </Step>

  <Step title="Start a new invoice">
    Click **New invoice**. You can build it from scratch or generate it from an
    existing [order](/guides/sales-customers/orders).
  </Step>

  <Step title="Add the customer and items">
    Choose a [customer](/guides/sales-customers/customers) and add line items —
    products from your catalog or custom lines with your own description and price.
  </Step>

  <Step title="Set due date and terms">
    Add a due date and any notes. Pick an
    [invoice template](/guides/sales-customers/invoice-templates) for the look.
  </Step>

  <Step title="Save or send">
    Save as a **draft**, or **send** it to the customer by email.
  </Step>
</Steps>

## Invoice status

| Status        | Meaning                                     |
| ------------- | ------------------------------------------- |
| **Draft**     | Being prepared, not yet sent                |
| **Sent**      | Delivered to the customer, awaiting payment |
| **Paid**      | Settled in full                             |
| **Overdue**   | Past its due date and unpaid                |
| **Cancelled** | Voided                                      |

## Sending & payment

Send an invoice by email and the customer receives a link to view and pay it via
the [customer portal](/guides/billing-addons/customer-portal). You can also export
an invoice as a **PDF** to print or share manually.

<Tip>
  Overdue invoices are flagged automatically so you can follow up. Keep customer
  email addresses up to date so reminders reach them.
