Hello Spiros.

Each service can have multiple durations. Since your appointments will come in as pending, you would be able to edit the appointment and change the duration from the back-end. For example, a customer books the default duration of 1:30 and after you determine you'll need 2 hours, you edit the appointment and change the duration:

Please note, though, that if another customer books an appointment after that one, and blocks the available time that could be changed, you wouldn't be able to change the duration.

For example, Customer 1 books an appointment at 09:00 which lasts until 09:30 + 30 minutes of buffer time (which is included in the total duration). If another customer books an appointment at 10:00, you won't be able to extend the duration of the first appointment, because the time will be blocked by the other appointment.

Buffer times are added to the Service settings.

Hi again Spiros.

I'm sorry to disappoint you, but unfortunately, there's no way to disable it through plugin settings.

Depending on the form, though, we may be able to send you custom CSS to hide it.

Can you please send me the URL where I can see the form (with the custom duration enabled)?

You're welcome, Spiros.

Please feel free to reach out to us if you have any further questions or concerns!
