AI Invoicing App Builder for Business Coaches
Stop rebuilding the same invoice in a document every week. Tell Mythex how your business coaching practice charges and it builds an invoicing app with clients, line items, totals, tax and a paid/unpaid list.
Who it's for
Owners of business coaches who want invoices numbered, stored and searchable without paying per month for accounting software.
What you can build
- Clients with billing details and payment terms
- Invoices with line items for one-to-one coaching and group programmes, tax and totals
- A PDF you can download or email to the client
- A paid / unpaid / overdue list with what is due this week
- Quotes that turn into an invoice once accepted
How business coaches work
A business coaching practice works with owners and founders on growth, leadership and focus. Clients usually sign up for a three to twelve month engagement with sessions every two weeks, sometimes alongside group programs, strategy days and mastermind circles. Leads come from referrals, speaking, LinkedIn and podcasts, and most start with a discovery call. Session notes, action points and goals often end up spread across documents, email and a calendar. Software helps keep each client's history, commitments and progress in one place.
What invoicing app for Business Coaches has to handle
- Engagements are often billed monthly or in a single upfront payment with a discount.
- Strategy days and mastermind seats are invoiced separately.
- Invoices to companies may need a company name and tax number.
- Payment plans need a schedule of future invoices.
A tip for business coaches
Bill engagements monthly with a fixed number of months, rather than per session. It keeps clients committed through the difficult middle of coaching and gives you steady income, while a paid-in-full option rewards those who prefer to pay upfront.
A prompt to start from
Build an invoicing app for a business coaching practice. Keep a list of clients with client name, business and programme. Create invoices with a number, date, due date, line items for one-to-one coaching, group programmes and strategy days, 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 set up a payment schedule for an engagement?
Yes. Create an engagement with a number of monthly invoices and they are generated on schedule. To charge cards on those dates, connect a payment provider account of your own.
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.
