AI Invoicing App Builder for Phone Repair Shops

An invoicing tool shaped like your phone repair shop: 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

Owners of phone repair shops 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 screen replacements and battery replacements, tax and totals
  • A PDF you can download or email to the customer
  • A paid / unpaid / overdue list with what is due this week
  • Quotes that turn into an invoice once accepted

How phone repair shops work

A phone repair shop lives on speed and trust. Most customers walk in with a cracked screen or failing battery and want it fixed the same day, while water damage and board repairs take longer and need a diagnosis first. Parts are ordered from suppliers, quality varies, and IMEI numbers need recording for every device. Refurbished phone sales add another stream. Tickets are often paper slips and phone calls asking about status pile up. Software helps by giving every repair a clear status and history.

What invoicing app for Phone Repair Shops has to handle

  • Repair invoices showing parts, labor and warranty.
  • Business invoices for multiple devices.
  • Deposits for parts ordered in.
  • Receipts for refurbished phone sales with IMEI.

A tip for phone repair shops

Print the warranty period, the part grade and the IMEI on every repair invoice. When a screen fails weeks later, you can tell at a glance whether it is your part and your warranty, and the customer cannot claim a different phone was repaired.

A prompt to start from

Build an invoicing app for a phone repair shop. Keep a list of clients with customer name, device model and IMEI. Create invoices with a number, date, due date, line items for screen replacements, battery replacements and water damage repair, 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 repair invoices include the warranty terms?

Yes. Add warranty details as a note or field on each invoice.

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.
