Book after payment is made

Hello,

How can I set the confirmation of booking after payment is made?
At the moment it says occupied after adding to cart and I dont want that..

Thanks..

Hi,
At the moment, when the time slot is selected, status of timeslot will be changed to Occupied. It means user can't select that time slot again. But if user doesn't complete the order, the time slot will be available for other customers.
Thanks
