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.

How do free trials work?

A parent books a trial in about 90 seconds. Their card is held, not charged. After the session, Kelvo turns them into a paying member — automatically after a cancel window, or with one tap from an email. You decide which.

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.

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.

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.

For martial arts clubs

Memberships, gradings and belts — without the admin.

Most of your income is a monthly membership, and most of your evenings go on chasing it. Kelvo takes the payment when a student joins, renews it on time, fills your gradings and seminars as paid bookings, and puts tonight’s register on your phone.

Sound familiar?

A standing order you have to check by hand

Students join on a membership that charges their card each month, with a reminder before and a receipt after. A failed card is retried and the parent is emailed for you; your customer list says paid, due or failed.

A beginner who books the black-belt class

Label students by grade — White to Orange, Advanced, Squad — and a class can require that label. Everyone can see the class; only the right belts can book it.

Gradings run on a clipboard and cash

A grading, seminar or competition is a one-off booking with its own price, capacity and register. Paid when they book; you know exactly who is coming and nobody pays on the door unless you want them to.

A free taster who never comes back

Offer a trial class on your booking page, take their details and consents up front, and have them on the register as new. Walk-ins are added at the door and are in the system for next time.

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

Invite-only classes

Label a child — Elite, Academy squad, Development — and a class can require it. Everyone else sees the class but cannot book it, and nobody is told which group they are missing.

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

Walk-ins and cash

Someone turns up unbooked: add them to the register on the spot and take cash, no card, no fee. They are in the system for next time.

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.

Selling

1-to-1 packs and slot generation

Turn a coach’s afternoon into bookable 30-minute slots in one go. Sell packs of 5 or 10; parents book slots themselves and a cancelled slot hands the credit straight back.

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 · London

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.

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.
