   * The charges will be included in the next recurring invoice and can be viewed on the pending invoice.

## Viewing and Managing Pending Invoice

A **Pending Invoice** refers to an invoice that contains charges scheduled to be merged into the next recurring invoice for a subscription-type booking. These charges are kept as pending and are not immediately issued. The Pending Invoice serves as a temporary holding place for these scheduled charges, allowing users to view, edit, and manage them (e.g., adding or removing items) before they are finalised.

The pending invoice can be found at the **top of the Booking → Billing → Invoices** list with the type **Pending**. This invoice only includes charges scheduled to be merged into the next invoice and does not contain the recurring charges for the booking.
