For gymnastics clubs

Capped classes, filled and paid, without the admin.

Recreational classes with strict ratios, squads on a monthly membership, holiday camps, and the consent and medical detail a coach has to have on the floor — one branded booking site, paid at the point of booking.

Ratios you can’t break, a booking page that lets people try

Every class has a capacity and every booking checks it — including mid-term joiners and moves. A full class says Full; a class that closes 24 hours out says Closed.

Termly blocks that reset your revenue every term

Sell the term, pro-rated for late joiners, and roll members into the next one automatically with a reminder before the charge. Or go monthly. Each class picks.

Consents and medical notes in a folder somewhere

Captured at booking, per channel for photos, restricted to the people who need them, and on the coach’s phone before the warm-up — with a call sheet for emergencies.

The waiting list in a spreadsheet

Leavers free a place, joiners are added from the customer list, and every family affected by a change hears about it in one email you wrote once.

What Kelvo does about it

Built for exactly this.

Selling

Memberships across classes

Bronze, Silver, Gold — a tier spans several classes, carries a joining fee, and gets its own page you can link from your site. Parents upgrade a tier and add a day themselves, paid on the card on file.

Selling

Camps — “three days, pick any two”

A pay-once camp over any dates. Sell a single day and a discounted bundle side by side; parents choose their days and pay once. Each morning has its own register.

Operations

A coach app that knows who is on the pitch

One-tap register on a phone. Before the session: who is new, consents, age, a medical flag and an emergency call sheet naming who to ring. Cover a session with another coach in one move. Never billing.

Money

Renewals that look after themselves

A reminder before every charge, a receipt after it, and a failed card retried and chased automatically. Your billing page shows what is coming in the next 30 days and who needs attention — in plain English.

Operations

Schedule changes, one email per family

Cancel a half-term, move a session, add a Saturday — Kelvo collects every change and you send one note per family covering all of it. Never sent without you.

Selling

Discount codes that go somewhere

Percent off, a waived joining fee, for the first N payments or for as long as they stay. Scope a code to a class or a plan, cap its uses, or send it to a list of families who have never booked.

Money

Account credit

Give a family goodwill credit and it is used automatically at their next booking or renewal. See every grant and where it went; refund it to card within 30 days if they ask.

Operations

Every change on the record

Who changed a price, cancelled a session or downloaded a register, when, from where, with the before and after. Sensitive actions are logged; you can answer any question a parent asks.

Your brand

No passwords, for anyone

Parents, coaches and staff sign in with a six-digit code by email. A returning parent is recognised at checkout and goes straight to payment.

In use

Organisations that got their time back — and made their income predictable.

SG Sport

Multi-sport

Moved off Omnify

From one-off blocks to recurring revenue

Every parent bought a block for the term, then had to be chased to buy the next one. Revenue reset to zero at every term boundary.

Live on Kelvo in days. Moved before the new term and put existing customers straight onto recurring plans. Renewals charge automatically, parents get a reminder first, and failed cards are retried and followed up without anyone lifting a finger.

Term-by-term chasing → renewals that run themselves.

The 7 Academy

Football · Surrey

Moved off GoTeamUp · Microsoft Bookings · Mailerlite · a bespoke website

Off four tools, onto one

Bookings on GoTeamUp, trials on Microsoft Bookings, emails on Mailerlite and a website that could not take a payment. Four logins, four bills, nothing talking to each other.

Live on Kelvo in days. Schedule, members and plans brought across; one branded booking site; parents book and pay in under two minutes; coaches mark registers on their phone.

Four systems → one. £0 a month.

Questions

Common questions.

Not answered here? Ask us — usually within a working day.

Can it do memberships, camps, 1-to-1s and termly billing?
Yes — all of them, on one booking site. Rolling memberships across several classes, pay-once camps (“three days, pick any two”), packs of 1-to-1 slots, termly blocks with pro-rata joining, and one-off drop-ins. Each class chooses how it is sold.
Is it GDPR and safeguarding compliant?
Consent is captured per channel (team chat versus public marketing), medical details are restricted to the people who need them, every sensitive action is logged, and data is stored in the UK. A Data Processing Agreement is available.
What do coaches see?
A mobile register for their sessions: one-tap present or absent, who is new, consents, age, a medical flag and an emergency call sheet naming exactly who to ring. Never billing. A head coach can take any register.
Is it really 4.9% and nothing else?
Kelvo charges 4.9% on each transaction and nothing else — no monthly fee, no setup fee, no per-seat charges, no contract. Card processing is handled by Stripe and billed by them at their standard UK rate (currently 1.5% + 20p for UK cards), the same as you would pay running Stripe on your own. When your classes are quiet, you pay nothing.
What happens with refunds and failed payments?
Refunds are one click, full or partial, and free up the places. A failed renewal is retried automatically and the parent is emailed to update their card; you see who needs attention on your billing page with the reason in plain English.
How do we move our schedule and members across?
We do it with you. Send us an export from whatever you use today — a spreadsheet is fine — and we set up your classes, plans and members so parents can book from day one. Most academies are live within days, not weeks.
Can parents cancel or change their booking themselves?
Parents can update their card, see every upcoming charge, book sessions from a pack, and upgrade a membership themselves. Cancellations and refunds stay with you — one click from the customer record — so a family always speaks to you first.

See it with one of your real classes.

We’ll set up a branded booking page with one of your real classes and walk through it with you live. 30 minutes.
