Hi Laura,

Thanks so much for your interest in Amelia. 

So 1st of all, if one service is booked next Friday at 10 am, I want then all the other services to be unavailable at this time, is that possible? - Yes, of course. You will be one employee and no overbooking will be possible. Once the appointment is booked the others are becoming unavailable for that period of time. 

Then I want to be able to say precisely when bookings can be made. For example, for one service which last 1h15mins it would be: Tuesday from 9.30 to 10.45 then from 10.45 to 12.00 But Thursday it could be 4pm to 5.15 and then 5.15 to 6.30 Is that possible? - Yes, you can define this in the employee's working hours, see the image below.

You can try this on our demo website: https://sports.wpamelia.com/

I am asking because with other plugins, the start day of each day has to be the same for one service. I'd also like to have only one booking page with all services available through a dropdown. Like the one you have to select a practitioner, except here there is only one practitioner who can perform several services so the dropdown list would be for services. - If there's just one employee the employee drop down will not be shown by default. 

Because I don't want a page that displays all services and then we have to click on one to make a booking. I want this to be a one page process. Lastly, do you have shortcodes available ? So that if for example I have already built a nice page on my website with a builder, showcasing a service, car I just add on this page the booking calendar through a hashtag? - Yes, you can see the list of shortcodes on our documentation: https://wpamelia.com/amelia-shortcodes/

Hope this helps and let me know if you have any additional questions.
