How it works

From a few words to a sent invoice in four steps

Every step is reviewable. The app never issues, numbers or sends anything without you.

  1. Speak or type the job

    “Three hours of design at 75 and 20 for materials, due in two weeks.” Say it or type it, in your own words.

  2. Review the draft

    AI extracts only what you said. Anything missing stays visibly missing for you to fill in. Nothing is issued until you approve it.

  3. Arrange your template

    Pick one of eight layouts, then reorder, show or hide blocks with native drag and drop, or with Move up and Move down buttons.

  4. Export and send it yourself

    Get a crisp PDF and a short email draft, then open your own mail app with the PDF attached. You press send.

Features

Everything an invoice needs. Nothing it doesn’t.

Templates that keep your data

Eight original layouts. Switch any time; every field and total stays exactly the same.

Voice or text to draft

Describe the work naturally. Your recording is uploaded only when you tap Generate.

Native block editor

Real SwiftUI and Jetpack Compose editors with undo, redo and accessible move controls.

Deterministic PDFs

Server-rendered A4 or US Letter with exact integer money math. Finalized invoices never change.

Email drafts, not email sending

A polite subject and body built from invoice facts only, opened in the mail app you already use.

Clients and price list

Save your business profile, customers and services. They fill empty fields and never rewrite old invoices.

Works offline

Templates, drafts, clients and your catalog live on your device. AI and PDF export need a connection.

Any currency

ISO 4217 handling with the right decimals, from USD cents to zero-decimal VND.

Private by design

PDFs and logos are stored privately and only ever served to your account. Analytics never see invoice contents.

Templates

Eight original layouts, one invoice

Switch templates whenever you like. Every field and total stays the same; only the design changes.

Built with guardrails

Fast should never mean sloppy

AI extracts. It never invents.

No made-up prices, dates, tax rates or contacts. Missing details are flagged, and totals are computed by the app, not the model.

Money is exact.

Amounts are integer minor units with explicit rounding rules, so what you see in the editor is what the PDF says.

You stay in control of sending.

The app drafts; your mail app sends. We cannot send, and we never claim to know whether an email was delivered.

Finalized means final.

An issued PDF and its invoice number are immutable. Changes create a new revision instead of rewriting history.

FAQ

Straight answers

Is this accounting or tax software?

No. FInvoice Maker creates ordinary commercial invoice documents and makes no compliance claims for any jurisdiction.

Does it send invoices for me?

No. It opens your own mail app with the PDF attached and an editable draft. You decide whether to send.

Can I use it without an account?

Yes. Templates and manual invoicing work as a guest. AI drafts, server PDFs and sync need a free account.

FInvoice Maker produces ordinary commercial invoice documents. It is not accounting software, a payment processor or a certified e-invoicing service, and it does not guarantee compliance with any tax authority’s requirements.
