Example: You book on for a session a week before the session, but suddenly you now can't attend that session. Currently how we do it: you put on one of the WhatsApp group chat for that session "Sunday fun session" I can't make it this Sunday, someone can take my place. Response: I will, send me you bank details so I can transfer you the money. How I would like it to be, you go on the app press the cancel button and then space becomes available for another person. When you cancel you receive a refund, You could also add if you cancel too late like a couple of hours before you don't receive the refund. You could also add notifications for cancellations, so that people know there is a free space. Also, you could add a reminder for people that they are booked on to the session, so that they turn up, and if they then can't turn up they are reminded to cancel freeing up the space for someone else. Also automatically add booked sessions to your calendar app so that you get reminders. Why do our club want this: As we are a popular pickleball club sessions fill up fast and we used to use Teamo chats to communicate but we filled the 250 people limit fast so had to move to WhatsApp. An example of this in detail 1. Booking a Session On Monday, Alex opens the SHARP Pickleball app and sees that the Sunday 10 AM fun session still has spaces. He taps "Book Now", pays £5 through the app, and it automatically adds the session to his calendar. Reminder & Calendar On Saturday, Alex gets a push notification reminder from the app: 🟢 “You’re booked for Sunday 10 AM Pickleball! Can’t make it? Cancel now to free your spot.” He also sees the event in his Google Calendar, with an alert set for 9 AM on Sunday. Unexpected Change On Saturday evening, Alex finds out he has a family commitment and can’t attend. He opens the app, taps “Cancel Booking”, and instantly gets a message: 🔄 “You’ve cancelled your session. A refund of £5 has been issued to your account.” 💡 Because it’s more than 12 hours in advance, he qualifies for the refund. Notification Sent to Others At the same time, Lisa—who was on the waitlist—gets a notification: 🔔 “A space has just opened up for Sunday 10 AM Pickleball! Book now before it’s gone!” She taps the link in the notification and grabs the spot. If Alex Had Cancelled Too Late If Alex had cancelled just 1 hour before the session, he’d see: ⚠️ “Sorry, it’s too late to cancel. No refund available.” But his spot would still be made available to others in case someone nearby could still take it. Benefits in Action Alex didn’t need to message a WhatsApp group. No sharing bank details or chasing money. Lisa got to play because of the notification. Everyone involved is kept informed and the process is simple, fair, and fast.
