Invoice Generator

Fill in your business, your client, and a few line items — get a clean, ready-to-send invoice, entirely offline, with nothing ever sent to a server.

Add your business info, your client's details, and a few line items, and watch a clean, professional invoice build itself live as you type. Print it or save it as a PDF using your browser's own print function — no server round-trip, no account, no per-invoice fee. Your business profile and recent clients are remembered locally so the next invoice takes even less time.

What it does

Most "free" invoice tools aren't as private as they look. Full platforms like Wave and Zoho Invoice require creating an account and store your client's name, address, and billing history on their servers indefinitely. PayPal's invoicing has no monthly fee but takes a 2.99–3.49% (+ a flat fee) cut of every payment collected through it. Even the "no signup required" web generators — invoice-generator.com being the clearest example — still work by sending your invoice data to their server, which renders the PDF and hands it back; there's no account, but your client's name and the dollar amount you're billing them still leave your machine. This tool works differently: the entire thing — the form, the live preview, the PDF rendering via your browser's native print engine — runs in a single HTML file with zero network requests. Nobody's server ever sees your client's name, address, or what you're charging them, because there is no server.

Who it's for: a freelance designer, consultant, or contractor who needs to send a professional-looking invoice today, doesn't invoice often enough to justify a monthly subscription, and would rather not put a client's contact details on a stranger's cloud server just to bill them.

Example scenario: a freelance designer wraps up a small branding project — a logo, a short brand guide, a few rounds of revisions — and wants to invoice the client that same afternoon. They open the tool, fill in their business details (remembered from last time), add the client, add three line items with quantities and rates, watch the total calculate itself including a 10% loyalty discount and local sales tax, and click "Print / Save as PDF." Two minutes later, a clean PDF is in their downloads folder, ready to email.

What it explicitly does not do: it does not send invoices by email itself (you still attach and send the PDF yourself), does not accept online payments or generate a "pay now" link, does not track whether a client has viewed or paid an invoice, does not sync across devices (recent business/client info is remembered in this specific browser only, via localStorage — not in the cloud), and does not import/export CSV or connect to accounting software. If you need payment collection, multi-device sync, or a client-facing payment portal, you want a full platform like Wave or Zoho — this tool is for the much more common case of "I just need to get a correct, good-looking invoice out the door without an account."

Features

• Live-updating invoice preview that's exactly what prints — no separate "generate" step to second-guess.
• Sequential invoice numbering that auto-advances each time you start a new invoice, fully editable if you need to match an existing numbering scheme.
• Automatic subtotal, percentage or flat discount, and percentage tax calculation, shown as clear line items on the invoice itself.
• Business profile and up to 20 recent clients remembered locally (via localStorage) so a repeat invoice takes under a minute.
• One-click "Print / Save as PDF" using your browser's own native print engine — no PDF library, no plugin, no upload.
• Built-in validation that catches missing business/client names, empty descriptions, and zero or negative quantities before you print, so you don't send an invoice with a $0 line item by accident.

Browser support

Plain-language summary for the listing: Verified on desktop Chrome (including a full automated test of every feature — form, math, validation, print, and saved data), and visually confirmed on desktop Safari and Firefox. Not yet verified on a physical iOS or Android device — if you're on mobile, it's built with only standard, widely-supported web features (plain HTML forms, localStorage, CSS print styles), so it's very likely to work, but this hasn't been confirmed hands-on yet.

FAQ

Does my file get uploaded anywhere?
No. This is a single HTML file with zero network requests — open your browser's developer tools and watch the network tab if you want to verify it yourself; nothing happens when you type, add line items, or click print. Your business info and recent clients are saved only in this browser's local storage, on your own machine.

Does this work on my iPhone/iPad?
It hasn't been verified on a physical iOS device yet (see the platform-support table above for exactly what has and hasn't been checked). It uses only standard web features with no exotic APIs, so it's likely to work, but this tool doesn't claim iOS support until that's been confirmed hands-on.

What happens to my file if I lose the download?
Your business info and this client's details are still saved in the tool (in this browser, on this device), so you can reopen the tool, re-add the same line items, and print again in under a minute. The generated PDF file itself isn't stored anywhere by the tool — once you save or print it, treat that file the way you'd treat any other document you care about (back it up, keep a copy in your invoicing folder). Unlike a cloud platform, there's no "invoice history" list inside the tool itself.

Can I use this for client or commercial work?
Yes. Every invoice you generate is entirely yours — no attribution required, no restriction on client-facing or commercial use.

Is there a subscription?
No. This is a one-time purchase of a single, self-contained HTML file. No recurring charges, no per-invoice fee, no feature paywall.
