Once an event is published, as the host, you will be able to see a list of the bookings in HoneyCal. You can add any of the subscribers to the list of bookings and can set any booking as "invited", "booked" or "cancelled". This means that you can easily add bookings for people if it is more convenient or they might have trouble making their own booking.
If you have set the track payments option, all bookings will be marked with the amount due based on the number of attendees times the price you set. You are then able to add payments on each booking to cancel off the amount due. You can add multiple payments, and note the amount and source (cash, cheque, bank transfer, etc). This is very useful especially when payments may be made in different ways at different times or when you host the same event regularly and people may pay for attendance in batches.
