Summer and winter price list with no manual switching
Enter summer and winter rates in advance and they switch over by themselves on the date you set. Within a season you grade prices as finely as you need, so morning clay can cost less than early evening.
Members and their prices
In tennis, the membership is usually the core of the club. Members have their own prices, even when you have agreed something different with one person than with the rest. A member sees it right at booking time, so nobody at reception is arguing over whether the discount applies.
Coaches and recurring sessions
Coaching hours, one-off or recurring, hold their place in the schedule and nobody books over them. A coach manages their own schedule and does not have to ring reception for every change.
