AI Invoicing App Builder for Property Developers
Stop rebuilding the same invoice in a document every week. Tell Mythex how your property developer charges and it builds an invoicing app with clients, line items, totals, tax and a paid/unpaid list.
Who it's for
Property developers 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 new-build units and off-plan sales, tax and totals
- A PDF you can download or email to the buyer
- A paid / unpaid / overdue list with what is due this week
- Quotes that turn into an invoice once accepted
How property developers work
A property developer sells homes before they exist. Off-plan launches, show home visits and investor packs drive reservations, while agents and brokers bring many buyers and need live availability. Each unit moves through reservation, deposit, contract and handover over months or years, with payment milestones tied to construction. Availability usually lives in a spreadsheet emailed to agents, which goes stale within days, so one live source of units, buyers and payments is the core need.
What invoicing app for Property Developers has to handle
- Payment schedules must be tied to construction milestones for each unit.
- Reservation deposits have to be recorded against the unit they secure.
- Agents should receive commission statements broken down by development.
- Buyers need reminders before each installment falls due.
A tip for property developers
Send buyers a clear schedule of every payment when they reserve, and a reminder before each milestone. Buyers who know what is coming pay on time. Rules on deposits and off-plan payments vary, so check the rules that apply where you operate.
A prompt to start from
Build an invoicing app for a property developer. Keep a list of clients with buyer name, unit and reservation date. Create invoices with a number, date, due date, line items for new-build units, off-plan sales and show home visits, 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 invoices follow construction milestones?
Yes, a payment plan can be set per unit with installments triggered when you mark a milestone complete.
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.
