AI Invoicing App Builder for Tennis Clubs
An invoicing tool shaped like your tennis club: your services, your tax rate, your terms. Describe it once, then issue invoices from a page instead of a template file.
Who it's for
Tennis clubs invoicing from a word processor or a spreadsheet, and chasing payment from memory.
What you can build
- Clients with billing details and payment terms
- Invoices with line items for court bookings and coaching, tax and totals
- A PDF you can download or email to the member
- A paid / unpaid / overdue list with what is due this week
- Quotes that turn into an invoice once accepted
How tennis clubs work
A tennis club is run largely by volunteers and a head coach, with membership renewing once a year before the outdoor season. Evenings and weekend mornings are when every court is wanted, while weekday afternoons sit empty apart from juniors and seniors. Members book by pegs on a board or a clubhouse sheet, coaches keep their own diaries, and the committee tracks subscriptions in a spreadsheet. Floodlight fees, box leagues, club nights and the summer tournament all compete for the same handful of courts.
What invoicing app for Tennis Clubs has to handle
- Annual subscriptions need invoicing by category, with family and junior discounts applied correctly.
- Coaching courses are usually billed per term, separate from membership fees.
- Floodlight and guest fees often accumulate as small charges that should roll up into one statement.
A tip for tennis clubs
Bill coaching by the term rather than per session, with a set number of weeks. It cuts the admin of chasing single payments and makes it easier to plan coach hours, while make-up sessions can be offered for weather cancellations.
A prompt to start from
Build an invoicing app for a tennis club. Keep a list of clients with member name, court and time slot. Create invoices with a number, date, due date, line items for court bookings, coaching and club sessions, 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
Can we collect subscriptions by card online?
The app can raise invoices and track who has paid. Taking card payments needs a payment provider account you connect yourself, such as Stripe.
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.
