# Set a reservation to 0 € (complimentary / invited guest)

> How to handle a reservation that should cost zero (invited guest, courtesy, compensation).

## When this case comes up

A reservation should be at 0 € for one of these reasons:

* **Hotel-invited guest**: press visits, FAM trips, owner's family, internal prizes.
* **Compensation for an incident**: a guest had a bad experience and is compensated with a free stay.
* **Initial charge error**: an amount was charged that shouldn't apply (for example, a promotion that wasn't applied when creating the reservation).

The path depends on where the reservation currently is. Start with the scenario that best fits your case.

## Create a new reservation at 0 € as an invited guest

If the reservation hasn't been created yet and you want to handle it as a complimentary stay:

<Steps>
  <Step title="Click Create reservation">
    From the calendar or main menu, click **Create reservation**.
  </Step>

  <Step title="Pick the Invited option">
    In the reservation type options, choose **Invited**.
  </Step>

  <Step title="Configure the reservation">
    Enter the guest data and stay details (dates, room, etc.).
  </Step>

  <Step title="Check the accommodation amount">
    For this reservation type, the accommodation **stays at 0 €** automatically.
  </Step>
</Steps>

<Note>
  You can still add **additional services**:

  * If the guest needs to pay for them, leave the regular price.
  * If they shouldn't be charged either, edit the service and set its amount to 0 €, just like on any other reservation.
</Note>

## Set an existing reservation to 0 € (no invoice issued yet)

If the reservation already exists but **doesn't have an issued invoice yet**, you can take it to 0 € applying a 100 % discount:

<Steps>
  <Step title="Open the reservation">
    From the calendar or the search, open the affected reservation.
  </Step>

  <Step title="Go to Price">
    In the **Reservation** section, go to **Price**.
  </Step>

  <Step title="Click Adjust prices">
    A popup opens where you can edit the rate, assign another room category or change the price.
  </Step>

  <Step title="Open See detail">
    Inside the popup, click **See detail**.
  </Step>

  <Step title="Enable the percentage discount">
    Turn on the **Show discount in percentages** option.
  </Step>

  <Step title="Apply 100 % discount">
    On the calendar at the bottom, apply a **100 % discount** to the corresponding dates. The total goes to 0 €.
  </Step>
</Steps>

## The reservation already has an issued invoice or a linked payment

If the reservation is already invoiced or has a recorded payment, **you can't modify the price directly**. A **corrective with a full credit note** is required, and we handle it from our side.

**Contact support** with:

* **Booking reference**
* **Reason** for the complimentary (invited guest, compensation, etc.)
* **If there's a linked payment**: whether the refund goes back to the original method (card, transfer) or stays as credit

We'll let you know when it's clean.

## When to contact support

**Whenever there's a validated invoice or a linked payment.** A corrective with a full credit note is only handled from the Odoo back-office.

<Warning>
  Don't void the validated invoice yourself or delete the payment. Fiscal numbering is irreversible, and voiding without the proper corrective can create a mismatch that gets reported to the tax authority (through VeriFactu in Spain).
