Stop Paying for Invoice Software. This Free Tool Runs Right in Your Browser.
Tharindu Dul · 2026-05-09 · via DEV Community

No subscriptions. No accounts. No data sent to anyone. Just open it and start invoicing. Link : https://invoicegeny.com/

If you run a small business, freelance, or do any kind of client work, invoicing is one of those necessary evils. You need professional-looking invoices, but the tools that create them either cost money every month, require you to create an account, or lock your data behind a login.

Invoicegeny is a free alternative that works differently. It runs entirely in your web browser. No sign-up, no subscription, no data ever leaving your device. Open it, set it up once, and start sending invoices in minutes.

Your Data Stays on Your Device

This is the biggest difference from every other invoicing tool.

Apps like FreshBooks, Wave, or QuickBooks store your business data on their servers. That means your client list, your pricing, your revenue, all of it lives somewhere you don’t fully control. If they change their pricing, get acquired, or shut down, you have a problem.

Invoicegeny stores everything in your browser’s local storage, the same place your browser saves your preferences and history. Nothing is sent to any server. Nothing is stored in the cloud. Your data is yours, period.

Set It Up Once, Use It Forever

The first thing you do is fill in your Seller Profile. This is your business info: name, logo, address, email, phone, tax ID, default tax rate, service charge, and bank account details. You fill this out once. Every invoice you create pulls from this profile automatically.

You can save multiple bank accounts and pick the right one per invoice with a single click. Currency is fully configurable — USD, EUR, GBP, LKR, and dozens more are supported out of the box.

Customers and Products - Managed, Not Re-Typed

One of the most tedious parts of manual invoicing is re-entering the same customer details and prices over and over.

Invoicegeny has a proper customer list and product catalogue. When you create an invoice, you search for the customer by name, phone, or email, it finds them instantly. Same with products: search, click, and the item appears on the invoice with the right price already filled in.

Adding the same product twice? It just bumps the quantity. No duplicate lines. If a customer or product doesn’t exist yet, you can add them right from the invoice creation screen,no need to go to a separate page first.

Create an Invoice in Under a

Minute

Once your profile, customers, and products are set up, creating an invoice is straightforward: pick a customer, search and add products, choose a payment method (Cash, Card, or Bank Transfer), set a due date, add any notes, and click “Save & Download PDF”.

A professionally formatted PDF downloads to your computer instantly, with your logo, your business details, the itemised list, tax, service charge, and total. Ready to send to your client.

Invoice numbers are assigned automatically in sequence (INV-0001, INV-0002…) so you never have to think about it.

The PDF Looks Professional

A lot of free invoice tools produce PDFs that look like they were made in 2003. This one doesn’t.

The generated PDF includes your logo in the top left corner, your business name and contact details next to it, “INVOICE” prominently on the right with the invoice number and dates, a clean items table with alternating row shading, an itemised totals section showing subtotal, tax, service charge, and the final amount, payment details at the bottom, and a footer.

It’s the kind of invoice that makes you look established and professional, even if you’re a team of one.

Track the Status of Every Invoice

Your invoices list shows every invoice you’ve created with its current status: Draft, Sent, Paid, or Overdue. You can update the status with one click. It’s a simple but effective way to know at a glance what’s been paid and what you still need to chase.

Press enter or click to view image in full size.

Who Is This For?

This tool is a great fit if you are a freelancer (designer, developer, photographer, writer, consultant) who invoices clients directly, a sole trader or small business, someone who values privacy and doesn’t want their business data on third-party servers, someone tired of paying a monthly fee for a feature they only use occasionally, or operating in any country — multi-currency support is built in.

Completely Free. Forever.

There’s no free tier with limits. No premium plan. No credit card required. The tool has no server costs because it has no server. It’s free to use because there’s genuinely nothing to charge for.

Open the app, fill in your seller profile, add a couple of customers and products, create your first invoice, and download the PDF. The whole setup takes about five minutes. After that, invoicing takes under a minute per client.
