The same handful of people
The fixtures secretary, the treasurer, the membership secretary. When one of them steps down at the AGM, what they knew leaves on their laptop.
Tennis club software
Clayside is club management software for UK tennis clubs. Members put in their own box league scores, answer the captain with a tap, book a court on their phone and pay their subs by Direct Debit. The same few volunteers stop doing it for them.

The committee's week
The fixtures secretary, the treasurer, the membership secretary. When one of them steps down at the AGM, what they knew leaves on their laptop.
Ladies' 1st, Men's 2nd, the mixed and the vets, summer and winter. Every county fixture starts with a WhatsApp round of who can play.
Matching the bank statement to the membership list, then chasing the ones who meant to pay and forgot.
One member list
Start with whichever job costs you the most evenings. A member is typed in once, and every part of the club reads the same list.
Players put the score in and their opponent confirms. Seven tennis formats, a championship tiebreak checked rather than trusted, and promotion that drafts itself at the end of the season.
How the box leagues work every planOne press asks the squad who can play Saturday. They tap yes, no or maybe, the captain picks from the yeses, and one tap puts the fixture in each picked player’s calendar.
How team selection works club plansCategories, families and juniors, with the subs by Direct Debit into the club's own account. We take no cut.
club plansMembers book on their phone and add it to their calendar. An agreed box match is one press from a free court.
club plansA ladder all year beside the boxes, and championship draws seeded to the LTA's regulations, plate and all.
every planA member posts when they are free, or a four that is one short. Players around their level see it, and the first yes takes it.
every planBox, ladder, tournament and club night results build one level per member, so someone who has played lands in the right box. It guides you and never decides for you.
every planA member asks your coach for an hour and the coach says yes. No phone numbers change hands.
club plansYour own address, with this year's fees and a join button, kept up to date from the club's own records.
club plansAn americano or a mexicano on a Friday: the app deals the courts, everyone plays to points, and the night ends with a table.
every planCounty leagues
Summer and winter, every team. One press asks everyone you asked last time.
For the captainNo more ringing round on a Thursday night to raise four.
A member taps yes, no or maybe. Only the captain sees who said no.
For the memberSaying no to a captain stops being awkward.
The side hears where to be and when, and one tap adds it to their calendar. Nobody plays for two sides on one day.
For the clubNo clash on court 3 on a Saturday morning.

Moving across
Court booking, members, subs, coaching and your website, with the box leagues, the ladder and the county teams on the same list of members. One system, so nothing is typed twice.
Your members
Paste or upload the spreadsheet you already export. Your columns are matched for you, and you check it before anything is saved.
At your own pace
Start with the leagues and the teams, then bring the court sheet and the subs across before renewals. We help you plan the move and do the fiddly parts with you.
Getting started
Paste your member list in and set up your first season. The first sign-in walks you through it on practice data, then clears it away.
No phone number or email is shown to another member, juniors included: only the officers you name can open the register. Built and run in the UK, held in the EU, and yours to download whole on any plan.
We help you set the club up and stay on hand through the season. Ask a question and a person replies.
It can pay for itself
The slot sits at the top of your league page and at the foot of every result picture members share. On a paid plan the name in it is yours to sell: a local physio, a coach or a builder. Clubs often sell it for more than the plan costs, and we take no cut.

Open the caseBefore you start
Not hard. Bring your members over from a spreadsheet, start with whichever job costs you most, and move the rest when it suits you. Before renewals is a good time. We help you through it, and a person answers when you ask.
It raises the side: who can play, who is picked, and where to be, and one tap adds the fixture to each player’s calendar. The league’s results still go wherever your county league asks for them.
It is a link on their phone, their name to tap and no password. If somebody would rather not, an organiser puts their scores in for them.
Through your club's own GoCardless account, by Direct Debit into the club's bank. Cash, transfers and cheques are recorded beside them. We take no cut.
Yes. The box league rules template is free to copy: fill in your club's name and dates, and pin it on the noticeboard. The rules template.
One box of up to 15 players is free, for as long as you want it: the live table, and the players putting their own scores in. After that every paid plan runs the same thing: as many boxes and seasons as you like, 8 club ladders, the championships, promotion and relegation, and career records. What you pay is set by how many members your club has. It starts at £120 a year or £12 a month, for a club of up to 125. Every paid plan carries a sponsor line on the league page, which is the one item here a club can turn straight back into money. See what is in each. The case for your committee. How the sponsor line works.
