How swim schools work
A swim school runs on pool time: weekday after-school slots and weekend mornings sell out, while daytime classes suit babies and adults. Children move through stages, so class lists change every time a swimmer earns a badge. Most schools rent lane space or a whole pool, charge monthly or by the term, and juggle waiting lists, make-up lessons and teacher cover. Records often live on poolside clipboards and in spreadsheets. Software helps most by linking each swimmer's stage to the right class and keeping parents informed.
What invoicing app for Swim Schools has to handle
- Termly or monthly fees are calculated from the number of lessons in the period, allowing for pool closure weeks.
- Sibling discounts should be applied automatically so the office never works them out by hand.
- Swimmers who join partway through a term need pro-rata fees for the lessons left.
- Crash courses and private lessons are charged separately from class fees.
A tip for swim schools
Publish the number of lessons in each term with the fee, and adjust for known pool closures in advance. Most billing complaints come from families who counted the weeks and found one missing, not from the price itself.
A prompt to start from
Build an invoicing app for a swim school. Keep a list of clients with swimmer name, parent contact and stage. Create invoices with a number, date, due date, line items for baby swimming, children's lessons and adult lessons, quantity, rate, tax and total. Generate a printable PDF, mark invoices paid or overdue, and show a dashboard of outstanding money. Add quotes that can be converted into an invoice, and store everything in a database.
Questions
Should swim schools charge monthly or per term?
Schools do well with either. Monthly direct payments smooth cash flow, while termly fees suit schools that follow the school calendar. Recurring charges need a payment provider set up under your own account.
Can it produce a PDF?
Yes. Ask for a printable invoice and Mythex builds a clean PDF layout with your details, logo and numbering, which you can download or attach to an email.
Does it handle tax?
Say which tax applies and at what rate and it is calculated per line and shown in the total. If you bill in more than one currency, say that too.
Do I need to know how to code?
No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.
Do I have to explain my business every time?
No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.
How much does it cost?
There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
