One app instead of five
Kassy replaces the paper diary, the spreadsheet, the calculator and the “did they pay me?” anxiety.
A calendar that knows your week
Recurring sessions that book themselves in, quick rescheduling, cancellations with a reason - and colours you pick yourself.
Every client, remembered
Contact details, personal prices, full session history and notes - so “how many lessons does Maria have left?” answers itself.
Sell packs, not chaos
Offer lesson packages and monthly subscriptions. Kassy counts down every credit and flags who's running low.
Invoices in one click
Turn finished sessions into a tidy invoice in seconds - with an online payment link your clients can open on their phone.
Polite chasing, automated
Friendly email reminders go out for unpaid invoices, so you never have to type that awkward message again.
Room to grow
Invite teammates, run several locations, and share a public page that always shows your real free slots.
Take a peek inside
Real screens from Kassy - this is what your admin could look like.
Your whole week at a glance
Sessions laid out in a clean weekly calendar, colour-coded by status, with the price right on each event. Create, move or cancel in a click.
A client list that runs itself
Names, prices, balances and history in one place. Every session and invoice files itself under the right person automatically.
From session to invoice in seconds
Kassy shows which sessions aren't billed yet, builds the invoice in one click, and tracks who has paid and who needs a nudge.
A payment page clients actually like
Every invoice links to a clean page where clients see what they owe and pay online in seconds - no account, no app, no printing.
