Quick answer: a ball machine locker for tennis venues
Tennis Machine SG (GX TECH PTE. LTD., UEN 202503838W) installs and operates a Smart Tennis Hub — a self-service locker holding a professional tennis ball machine, 130+ pressureless balls, a cart and a ball picker — at Singapore sports centres, tennis academies, hotels, schools and other court venues, with no capital expenditure or staffing for the operator. Players book, pay and unlock it from their phones, which gives solo players a reason to book courts at off-peak times. Tennis Machine SG pays the venue a base rental plus a share of the gross rental revenue generated at the site, or a fixed rental, gives the venue its own page on tennismachine.com.sg, and starts every placement with a risk-free 3-month pilot.
Who It Works For
Sports centres & court operators
A self-service amenity that turns quiet hours into bookable ones, and gives players a reason to choose your courts.
Tennis academies & coaches
Players practise between lessons, coaches set drills to work on, and recurring weekly slots can be held for your programmes.
Hotels & resorts
A ball machine guests can book from their phone, with nothing for the front desk or a sports desk to run.
Schools & institutions
Courts that sit idle outside timetabled sessions, opened up for self-service practice without adding staff.
Corporate campuses
A staff wellness amenity on the company’s own courts, run entirely by us and at no cost to facilities.
Empty Courts Are a Partner Problem
Most quiet court hours aren't a lack of players — they're players without someone to hit with. Plenty of people would book a court at 7am or 3pm on a weekday if they had a partner. A ball machine is that partner, available whenever your courts are.
The Hub doesn't take court time from anyone. Players book the court with you, exactly as now, and reserve a machine slot to match — so every machine session is a court booking you might not otherwise have had.
-
Off-peak becomes bookable
Solo players fill early mornings, weekday afternoons and late slots that doubles groups never ask for.
-
Practice drives play
Players who drill on their own between matches and lessons play more — and book more court time to do it.
-
Coaches get a practice partner
Coaches can set homework drills on the machine, and academies can hold recurring weekly slots for their programmes.

Your Venue Gets Its Own Page on Our Site
Every public Hub gets a location page of its own — directions, a map, live machine status and booking links — written to be found by players searching for ball-machine practice near them, and listed on our locations page. Every player who books a machine at your Hub needs a court from you to use it on.
Commercial Terms for Venues
Venues with steady court traffic usually do best sharing the upside; a fixed rental is there if you'd rather have certainty.
Recommended for venues
Base rental + revenue share
A base rental covering electricity, plus a share of the gross rental revenue the Hub earns at your courts, calculated from monthly Stripe statements. The busier the Hub, the more you earn.
For certainty
Fixed rental
A flat monthly rental, indicatively from S$60 per site, inclusive of electricity. Nothing to reconcile, and simple to budget.
Term
One year, auto-renewing, terminable by either party on one month's written notice, after a risk-free 3-month pilot. We're equally happy to adopt your standard concessionaire or licence terms.
Proof, not a pitch deck
Already Running, With Nobody on Duty
Our first locker has rented out a professional ball machine with no staff present since early 2026. It sits at Yew Luck Luck Convenience Store, a short walk from the courts at ActiveSG Sport Village @ Jurong Town: players book online or scan the QR code, then pay, unlock, play and return everything themselves, at any hour. Everything a host venue gets already runs there — the booking app, card payments, verified accounts, the deposit hold, remote unlocking and support.
Jurong locker: open 24/7
- ✓Operated by GX TECH PTE. LTD., a registered Singapore company (UEN 202503838W)
- ✓Card payments by Stripe; every player has a verified account and accepts our Terms of Service and Liability Waiver before the locker opens
- ✓Public liability and equipment insurance carried by us
- ✓Rated 5.0 by players on Google
“The machine was easy to set up and use, even for someone not very technical.”
Why Not Just Buy a Ball Machine?
Buying one looks simpler until someone has to own the bookings, the keys, the charging and the repairs. Here is the comparison side by side.
Compare buying a machine with hosting a Hub
| Topic | Buy a machine yourself | Host a Smart Tennis Hub |
|---|---|---|
| Upfront cost | A four-figure purchase — typically S$1,200 to S$3,000 or more for a reliable battery model — plus balls, a cart and lockable storage | Nothing. We fund the cabinet, the machine, 130+ balls, the cart and the picker |
| Bookings & payments | Someone keeps a booking sheet and collects fees — or it is free, first-come and nobody keeps track | Our booking app, 24/7, paid by card through Stripe |
| Keys & handover | Staff or security sign the machine out and back in | None — the cabinet opens only for the player who booked |
| Charging, balls & repairs | Your team charges batteries, replaces worn balls and arranges repairs | Ours: regular site visits, ball replacement and servicing |
| Damage & misuse | The venue pays to repair or replace | A refundable S$200 deposit hold on every session, plus our equipment insurance |
| Liability | Falls on the venue as the equipment provider | Our public liability insurance, and a waiver every player accepts before the cabinet opens |
| Money | A cost line in the budget, every year | A base rental plus a share of the revenue the Hub earns at your courts |
| If it doesn’t work out | You own an idle machine | We remove it at our cost and make good the space |
Who Does What
We do 100% of the work
- ✓Provide, install and maintain the cabinet and the machine at our own cost
- ✓Carry public liability and equipment insurance
- ✓Handle every booking, payment, refund and dispute online
- ✓Run all customer service and technical support — users never approach your counter or courts staff
- ✓Attend site on a regular schedule to test equipment, replace balls and keep the area clean
- ✓Brief your front-desk or courts team so they can speak to it knowledgeably
- ✓Remove the unit and make good the space if the arrangement ends
You provide two things
- ✓A micro-space of approximately 90 × 60 cm beside or near the tennis court
- ✓Access to a standard 3-pin electrical socket (230V)
That's the entire ask.
No staffing, no keys to issue, no stock to manage, no incident handling, no capital expenditure, and no change to how your courts are booked. Electricity is minimal — roughly 15–20 kWh a month at maximum usage, about S$6–S$8 — and is covered in the commercial terms.
What Actually Gets Installed
A weather-sealed smart cabinet about the size of a household fridge, sited beside or near your courts without obstructing walkways. It needs about 90 × 60 cm of floor and one 3-pin socket.
-
Scan, pay, unlock
Players book ahead or scan the QR code on the cabinet’s screen, then collect with a six-digit pickup code. No app, no keys, no staff.
-
Checks every item back in
Sensors confirm the ball machine, cart and racquets have come back before a session settles, and the deposit hold is released automatically.
-
Charged for every session
The cabinet charges the machine’s battery packs and hands out one with enough charge to finish the booking.
-
Works even offline
Pickup codes are checked on the cabinet itself, so a dropped internet connection never strands a player at the door.
-
Monitored as it happens
Every door, item and battery event reports to our system in real time, so a fault shows up on our side straight away.
-
Finished for your venue
Cabinet finish and branding matched to the estate or clubhouse, including discreet, unbranded treatments.

| Weather rating | IP65 sealed cabinet — built for outdoor placement beside the courts |
| Power required | One standard 3-pin 230V socket |

| Noise | Quiet electric motors, comparable to normal conversation |
| Contents | A professional ball machine with adjustable speed (15–110 km/h), spin, feed rate and oscillation, plus 130+ pressureless balls, a transport cart and a ball picker. Machine choice can be tailored to the venue. |
| Optional compartments | Rental racquets, balls, grips and accessories can be dispensed from the same cabinet — or left unstocked so there is no overlap with your own pro shop |
| Access & payment | Browser-based booking and unlocking (no app install), payments via Stripe, every user digitally verified and waiver-accepted |
| Finish | Cabinet finish and branding can be matched to the estate or clubhouse environment, including discreet, unbranded treatments |

Court Operator FAQ
How does a ball machine increase tennis court utilisation?
A self-service ball machine removes the most common reason a court sits empty: not having a hitting partner. A Smart Tennis Hub from Tennis Machine SG lets solo players book a court and practise alone at off-peak times, and gives coaches a practice tool between lessons, turning quiet hours into bookable ones.
How does the Smart Tennis Hub revenue share work for court operators?
Tennis Machine SG pays a court operator a smaller base rental covering electricity plus a share of the gross rental revenue the Smart Tennis Hub generates at that venue, calculated from monthly Stripe statements. Operators who prefer predictability can take a fixed monthly rental instead.
Can a tennis academy reserve the ball machine for its programmes?
Yes. Recurring weekly slots on a Smart Tennis Hub can be reserved for an academy’s coaching programme, and coaches can also book the machine like any player. Tennis Machine SG can block the Hub out on request for tournaments or events.
Will our venue be listed on the Tennis Machine SG website?
Yes. Every public Smart Tennis Hub gets its own location page on tennismachine.com.sg, with directions, a map, live machine status and booking links, and is listed on the Tennis Machine SG locations page. Venues that prefer to stay private can be left off.
Does the Smart Tennis Hub connect to our court booking system?
No integration is needed. Machine rental through Tennis Machine SG is separate from the venue’s own court booking system — players book the court with the venue as usual and reserve a machine slot to match. Where a venue wants it, Tennis Machine SG can also digitise the court booking process itself.
Can hotels and resorts offer the Smart Tennis Hub to guests?
Yes. A Smart Tennis Hub gives a hotel or resort with tennis courts a self-service ball machine amenity for guests, with booking, payment, support and servicing all handled by Tennis Machine SG and nothing for the front desk or sports team to run.
What does a venue need to provide to host a Smart Tennis Hub?
A venue hosting a Smart Tennis Hub provides about 90 by 60 cm of floor space beside or near its courts and one standard 3-pin 230V socket. Tennis Machine SG funds, installs, insures and services the cabinet and machine, handles all bookings, payments and support, and removes the Hub at its own cost if the venue is not satisfied during the 3-month pilot.
