The Problem

Tired of paying monthly just to send an invoice?

Most invoice tools treat you like a recurring revenue opportunity — not a person who just needs to get paid.

Subscription creep

$15/month. $20/month. $30/month. It adds up fast. You’re paying for invoicing buried inside a bloated suite you never fully use.

Forced sign-up walls

“Free” invoice generators gate every useful feature behind an account. Then they email you forever. Then they upsell you.

Your data in someone else’s cloud

Your client names, rates, invoice history — on a third-party server. One breach. One acquisition. One policy change. Gone.

Internet dependency

Working from a train, a remote cabin, or a venue with spotty WiFi? Good luck invoicing when the tool won’t load.

The Solution

Your client data belongs on your device

Invoice Generator runs entirely in your browser. No server. No account. No middleman between you and your invoice.

No internet required

Once downloaded, works anywhere — on a plane, in a basement, at a client site without WiFi.

No account, ever

Open the file. Start invoicing. No email address. No password. No activation. No tracking.

Zero data transmitted

The tool makes zero network requests. Nothing is uploaded, logged, or stored outside your device.

Buy once, own forever

No renewal. No price increase. No “we’re sunsetting this plan” email. Pay once. It’s yours.

Features

Everything you need. Nothing you don’t.

No bloat. No upsell. A focused, professional invoicing tool that does its job.

Live invoice preview

Your invoice updates in real time as you type. What you see is exactly what your client receives.

Professional PDF export

Generate a clean, professional PDF with one click — entirely locally, no server involved.

Logo upload

Add your business logo to every invoice. Stored locally in your browser as base64 — never uploaded.

Multi-currency

Set your preferred currency (USD, EUR, GBP or custom symbol). Supports international billing out of the box.

Auto invoice numbering

Invoice numbers auto-increment from your last invoice. Always editable if you need a custom format.

Precise tax calculations

Integer-based arithmetic eliminates floating point drift. Correct to the cent, every time.

Settings persist locally

Your company name, address, bank details, and logo are saved locally between sessions. Fill once, invoice forever.

Any device, any OS

Runs in any modern browser on Windows, macOS, Linux, and ChromeOS — desktop or laptop.

Data stored in cloud   On their servers   Stays on your device

FAQ

Frequently Asked Questions

Does Invoice Generator work offline?
Yes. Invoice Generator is a single HTML file that runs entirely in your browser. Once downloaded, it works without any internet connection — on a plane, in a café with no WiFi, or anywhere else.
→ Full guide: Offline Invoice Generator
Do I need to create an account?
No. There is no account, no sign-up, and no login — ever. Open the file in your browser and start invoicing immediately.
→ See why freelancers choose Invoice Generator
Where is my data stored?
Your company settings (name, address, bank details, logo) are saved in your browser’s localStorage — on your device only. Invoice data (client, line items) is session-only and is never saved or transmitted anywhere.
What browsers does it work in?
Invoice Generator works in any modern browser: Chrome, Firefox, Safari, Edge, and Brave — on Windows, macOS, Linux, and ChromeOS.
Does it generate real PDF files?
Yes. PDF generation happens 100% locally in your browser using an embedded library. No data is sent to any server. The PDF is created and downloaded directly on your device.
Is this a subscription?
No. Invoice Generator is a one-time purchase. You buy it once and own it forever — no monthly fees, no renewal reminders, no price increases.
→ See how Invoice Generator compares to FreshBooks & Wave
What happens to my data if I close the browser?
Your company settings persist in localStorage and will be there next time you open the file. Invoice data (client info, line items) is intentionally session-only and clears when you close the tab — your client’s data is never stored anywhere.
Is this tool GDPR-compliant?
Yes. Invoice Generator collects zero data. It makes no network requests, has no analytics, no cookies, and transmits nothing. Your client data and invoice data never leave your device.
Can I use it on Mac and Windows?
Yes. It works on any operating system that runs a modern browser — Windows, macOS, Linux, and ChromeOS.
What is the difference between this and FreshBooks or Wave?
FreshBooks and Wave are cloud SaaS tools: they require an account, store your data on their servers, charge monthly fees, and require an internet connection. Invoice Generator is the opposite: no account, no cloud, no subscription, works offline, and your data never leaves your device. You pay once and own the tool forever.

Stop paying monthly.
