Booking options (bookable offers) can be added, edited or canceled in the booking details. If individual booking options are to be removed, the *Cancel* option should be used and **not Delete**. *Delete* is only recommended if an element that has just been added is to be removed again during editing (before the invoice is updated).

Typical use case: Changing a workshop selection. To do this, the existing offer must be edited and the workshop selection can be changed in the details (Fig. 2: point 3)

When changing the price group, the option *Calculate price based on price group again* can be selected so that the price is automatically adjusted after saving (Fig. 2: point 1).

The tax rate can also be adjusted (Fig. 2: point 2). If a handling fee is to be charged, further information can be found [here](https://manual.converia.de/en/attendees/manage-persons-and-attendees/managing-bookings-and-invoices/cancellation-at-a-glance/editing-or-canceling-booking-options/charge-a-handling-fee-and-show-it-on-the-invoice).

* Finally, the invoice must be updated before the editing process is completed and a new invoice document is created.
* The comment function can be used to document changes or deviations for other Users in the backend.
* No automatic emails are triggered when edits are made in the backend. If required, the participants can be informed via *booking info mail* (sent to the person who booked in, tab in the booking details) or *invoice info mail* (sent to the invoice recipient, tab in the invoice details).

#### Important next steps

If a free booking becomes a chargeable booking, please remember to [adjust the payment method](https://manual.converia.de/en/attendees/setting-up-the-registration/basic-setup-of-the-registration/methods-of-payment) on the invoice accordingly.

If an additional payment is due, please inform the participant. You can find details of the procedure [here](https://manual.converia.de/en/ticketing-processing-with-converia/general-information/send-payment-information-for-subsequent-payment).
