Make sure that you opened up the slot for the class under "Calendar"
To open up an available slot for a Class Service, you firstly need to book the slot into your calendar. To do so just click on the date and time you want to open up the slot for. Now select the Class Service from the drop-down provided and complete the booking.
When opening up the slot for your Class Booking make sure that you assign a location to the booking, as otherwise, 10to8 cannot show this slot as available.
Make sure that your class is not fully booked under "Set Up" > "Services"
To check the class capacity click on the service you are missing slots for. Now check the number of attendees you have set up and go to your "Calendar".
On your calendar go to the date and time you are missing the slot for and check how many customers have already booked. You can do this by counting the bookings next to the original appointment you booked to open up the slot.
If the number of attendees is the same as the one on the “Services” page, then your class is fully booked out and 10to8 will not be able to show further slots.
Check your notice period under "Set Up" > "Services"
The notice period limits your customers on how many hours/days they have to give you notice before being able to book. As a default setting, we use 24 hours which means that the earliest available slot is 24 hours or more in the future.
To edit this, click on the service you want to change the notice period for. Now you can use the drop-down provided on the page.
