Court booking · ProShop · café — one system
Zentr Sport is a court booking and venue management system for badminton, tennis and pickleball that brings court booking, the ProShop and the café into one system. Customers book courts themselves via LINE around the clock, with no one watching the chat.
The problem
Most venues note bookings in a counter notebook, take more over chat, and get still more by phone. Those three channels don't know about each other. The gap between someone taking a booking and someone writing it in the book is exactly where double-bookings happen.
Everything in it
A venue is three businesses stacked together — selling court time, selling gear, and selling food and drink. Here they're one system: one court map and one point of sale.
One court map every channel sees the same — the counter, the booking website, and LINE OA. Overlaps can't happen at the source.
Retail sales with stock tracking, and a restringing queue you no longer note on sticky paper.
Food and drink sell through the same POS as the ProShop — no extra program.
Why a system
The problems aren't because people work badly. They come fromlimits no one, however good, can get past — a system doesn't replace people, it just exists in many places at once.
At the busy early-evening peak, one staffer can't take money, answer the phone and reply to chat all at once. A system can be everywhere at once.
Between taking a booking and writing it down, that court still looks open to someone else. The system locks the court the second it's booked.
People ask after work and before bed — hours the venue is already closed. Unanswered, they ask another venue the same night.
Which group books which day, who's paid and who hasn't — today that lives in someone's memory. The day they quit, the system still remembers.
How it works
From the first message to paying up and heading home — all on one timeline.
A customer
“Any courts left at 7pm tomorrow? We'll take 2” — Zentr understands the shorthand, typos and real wording players use.
Zentr
It reads all 6 courts, subtracts existing bookings, reserved regular groups and courts closed for repair, then replies with the correct early-evening price.
Zentr
The customer picks courts 3 and 4 and pays the deposit via PromptPay in chat. The system locks the courts that second; anyone who messages later won't see those slots.
During play
Sold from the same screen. Shuttlecocks are deducted one at a time from an open tube, not the whole tube.
The next morning
Past bookings are in the system — no notebook to open, no chat to scroll.
Features
A sports venue sells space by the hour to groups who come back every week and buy food while they play. Below is what the system does today — including what it doesn't yet.
Almost every after-hours question is “any courts left tomorrow?” — which the system answers itself from the real court map.
Regular groups are a venue's most predictable income. The system reserves courts ahead on the schedule you set.
A screen a late-shift staffer learns in ten minutes. See the whole day's court map on one page; open a bill, move a court or extend time without changing screens.
Search who booked what and when. This part is still basic — you can see past bookings and sales, but there are no charts or analytical reports yet.
In the real product
Not mock-ups — every one is taken straight from the Zentr Sport Platform.
What changes
Who it's for
If your revenue is hours times courts, every empty court-hour is already expired — you can't sell it back. Zentr Sport is built for exactly this business.
