01What it does

One job, start to finish.

Quote the job, invoice the client, receipt the payment — each document created from the last, numbered automatically, never retyped.

Nº 01

Quotation → Invoice → Receipt

Turn an accepted quotation into an invoice, and a paid invoice into a receipt, in one tap. References and numbering follow automatically.

報價單、發票、收據一條龍
Nº 02

Installment invoices

Split a quotation into deposit, delivery and balance invoices — by percentage or by line item — and issue each stage when it falls due.

分期開票：訂金、落貨、尾數
Nº 03

On-device AI drafting

Describe the job in English or Cantonese and the form fills itself. The AI runs entirely on your device — offline, private, no cloud.

Your company identity

Logo, company chop, signature and bank details — including FPS — laid out on three refined templates. Trusted, familiar, and unmistakably yours.

公司印章、FPS 收款資料

PDF and editable Word

Every document exports as a print-ready PDF, plus an editable .docx when a client insists on last-minute wording changes.

PDF 同 .docx 都有
Nº 06

iPhone + Mac, one purchase

A true native app on both — one purchase, both platforms. With Pro, iCloud sync puts the invoice you make on your Mac in your pocket when you meet the client.

一次購買，兩邊都用

02On-device AI

Say it in Cantonese.
It becomes invoices.

Type 「訂金三成，落貨五成，尾數兩成」 and InvoiceGen drafts the three installment invoices — amounts computed exactly, totals guaranteed to balance. The language model runs on your iPhone's own chip: nothing you type is ever uploaded, and after a one-time 280 MB download it works with no connection at all.

RUNS ON YOUR DEVICE — NOT IN A DATACENTER

03Privacy

No servers. No accounts. No analytics. Your clients' business stays your business.

Every document, client record and company detail lives on your device — or, if you turn on sync, in your own private iCloud where we have no access. The App Store privacy label reads "Data Not Collected", because there is nothing to collect. Read the privacy policy.

05Questions

Asked often, answered plainly.

Where is my data stored?

On your device. If you enable iCloud sync (Pro), it also lives in your personal iCloud — under your Apple ID, where the developer has no access. There are no InvoiceGen servers at all.

Does the AI send my text anywhere?

No. The language model downloads once (about 280 MB) and then runs entirely on your device. You can use Quick Draft in airplane mode.

Can I use it in Chinese?

Yes — the interface and documents work in English and 繁體中文, and the AI understands Cantonese phrasing like 「訂金三成，落貨五成，尾數兩成」.
