About SEDI Invoice Generator

A free, no-sign-up tool for generating professional invoices, credit notes, and receipts. Built to fill a simple gap: creating a clean invoice PDF without creating an account.

Why this tool exists

Invoicing is one of those tasks that feels simple until you actually sit down to do it. The work is finished, the client is waiting to pay, and suddenly you're staring at a blank document trying to remember what a professional invoice is supposed to look like.

What this tool does

The SEDI Invoice Generator is one of the tools created by SEDI. It is a free browser-based app for creating professional invoices, credit notes, and receipts. There is nothing to install and no account to create: open the page, fill in the fields, and download a print-ready PDF.

There are plenty of invoicing tools available. Many require account creation and limit what the free tier can do. This tool takes a different approach: fill in some fields and download a PDF. No account, no watermark.

The tool does exactly one thing: turn form fields into a clean, print-ready PDF. No login, no onboarding tour, no "upgrade to pro" nag. Land on the page, type the details, and click Download.

What you can do with it

The tool supports three document types, because many businesses need more than just an invoice template:

• Invoices - the standard one. Send it to a client after you finish a project or at the end of a billing cycle. Includes line items, tax, discounts, shipping details, and payment terms. You can mark it as paid, unpaid, or partial (shown as a status badge), and entering the amount paid shows the remaining balance on the PDF.
• Credit Notes - when you need to correct a previous invoice. Maybe you overcharged, or the client returned something. A credit note is the proper way to handle it instead of just sending a revised invoice and hoping nobody notices the discrepancy.
• Receipts - for when the client already paid and just needs a proof of payment. Receipts skip the due date and default the payment status to "paid", since the payment's already done.

Each document type changes the labels and fields automatically. Switch from Invoice to Credit Note, and the total line changes from "Total Due" to "Credit Amount." The little details matter when you're sending professional documents to clients who've seen hundreds of them.

Multi-currency support

Those who work with international clients often need to invoice in multiple currencies. The currency dropdown includes 25 currencies with correct locale formatting - JPY shows zero decimal places, EUR uses the European number format, and the currency symbol matches the right country flag. It's an easy detail to overlook until a client in Germany receives an invoice that says "$1,000" when they expect "1.000,00 €."

Themes and structure

Everyone has an opinion about how an invoice should look. Accountants want clean, dense layouts with everything on one page. Creative agencies want something modern with plenty of whitespace. Law firms want traditional, maybe even a bit formal.

That's why there are 30 color themes and 11 layout structures. Pick a Classic theme with a Compact structure for a law firm, or an Ocean theme with a Modern structure for a design agency. The preview updates in real time as you make changes, so there's no guessing what the PDF will look like.

The Slate theme with the Minimal structure offers a clean, distraction-free look. For clients in more traditional industries, the Classic theme with the Traditional structure is a better fit.

Privacy-first design

There's no database and no backend server. All data stays in the browser. Everything you enter is processed in your browser and never transmitted to a server - there's no cloud copy. The form fields and preferences are saved in your browser's localStorage on your device. Because everything is local, it persists in that browser until you clear your browser's data for the site, and it won't be available on a different device or browser. Returning visitors don't have to reconfigure the form from scratch.

This matters because some invoicing tools store financial data on their servers by default. That's a legitimate concern for many users. Client lists and payment history shouldn't end up on a server somewhere just because someone needed to send an invoice.

No sign-up. No watermark.

The tool is designed as the opposite of a SaaS upsell funnel. There's no free tier with a hard cap. Generate as many documents as needed, try every theme, change currencies as often as needed. The PDFs are clean, with no "Generated by SEDI" watermark or branding on the document itself. The only place the SEDI name appears is on the website.

The tool is free, and SEDI keeps it simple and affordable to run. It's not a revenue-driven product - it's a utility. If it saves ten minutes of formatting an invoice by hand, then it's doing its job.

What's next

There's a small list of features under consideration: recurring invoice templates, bulk PDF export, and a simple dashboard showing total invoiced amounts across sessions. The goal is to avoid bloat. Feature requests can be submitted through the contact page.

How it works under the hood

The form renders a live preview that updates as you type, and the Download button produces a clean, print-ready A4 PDF directly from that preview. Because the document is assembled from the same layout you see on screen, what you preview is exactly what you get in the file. There's no disconnect between the on-screen layout and the downloaded PDF, which can happen with template-based generators that render differently in the browser than in the download.

Each of the 30 color themes applies a consistent set of design choices - accent colors, heading fonts, body fonts - across the entire document. When switching from Classic to Ocean, the preview updates instantly with no page reload. The structure system works the same way, with each of the 11 layout options changing the arrangement of padding, margins, font sizes, and table styling.

This is intentional. The tool is designed to work reliably on any device without requiring a server to render pages. Everything runs in the browser. The PDF is assembled locally. If the internet goes down halfway through creating an invoice, the flag images disappear but everything else still works.

Who this is for

The tool is built for solo practitioners and small teams. For those billing one to fifty clients a month without needing inventory management, time tracking, expense categorization, or team permissions, a full-featured invoicing platform is overkill. Those platforms charge for features most users never use and present a UI optimized for accounting departments.

The tool also suits people inside larger organizations - consultants who need a quick invoice for a one-off engagement, contractors who work with multiple agencies and don't want to set up profiles in each one's preferred system, and independent wedding photographers who send invoices alongside photo delivery links.
