AI Invoicing App Builder for Lash and Brow Studios

An invoicing tool shaped like your lash and brow studio: 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

Lash and brow studios 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 lash extensions and lash lifts, 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 lash and brow studios work

A lash and brow studio lives on repeat visits: extension clients return for infills every two to three weeks, and lifts and brow lamination come back every six to eight. Saturdays and the weeks before holidays and weddings fill first. New clients need a patch test some time before their first treatment, and each technician keeps notes on curl, length and thickness, known as the lash map. Bookings come through social messages and a booking link. Software helps by keeping patch tests, lash maps and rebooking in the client's record.

What invoicing app for Lash and Brow Studios has to handle

  • Deposits on first full sets and cancellation fees for no-shows.
  • Invoices for training courses paid in installments.
  • Voucher redemptions recorded against the original sale.
  • Chair rental invoices for self-employed technicians.

A tip for lash and brow studios

Take a deposit on every first full set. It is a two-hour appointment with a new client, and a no-show costs a full afternoon; clients who pay a deposit arrive far more reliably.

A prompt to start from

Build an invoicing app for a lash and brow studio. Keep a list of clients with client name, phone and lash map. Create invoices with a number, date, due date, line items for lash extensions, lash lifts and brow lamination, 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 invoice technicians who rent a chair?

Yes. Set up recurring chair rental invoices per technician, weekly or monthly.

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.
