Summary
About Invoice Generator
The Invoice Generator is a free, browser-based tool that lets freelancers, small business owners, and contractors create professional invoices in minutes without any accounting software. Fill in the issuer and receiver details including company name, business registration number, and address, then add one or more line items with item name, quantity, and unit price. The tool automatically calculates the subtotal, applies your chosen tax rate to compute the tax amount, and displays the grand total — all updating in real time as you type.
This tool is designed for anyone who needs to issue a quick invoice or tax bill without the overhead of a dedicated billing platform. It supports both Korean (세금계산서 format) and English (INVOICE format) layouts, and handles edge cases gracefully: you can add multiple line items, remove any item except the last one, and adjust the tax rate freely. The print layout uses CSS media queries to hide the input form and display only the clean, printable invoice document.
When you click "Print / Save PDF," the browser's native print dialog opens. You can choose to print on paper or save directly as a PDF using your browser's built-in PDF export. Since all data is entered and processed client-side, your invoice details — including sensitive business registration numbers and financial amounts — never leave your device. There is no server storage, no account, and no subscription required.

Frequently Asked Questions
Can I save the invoice as a PDF?
Yes. Click "Print / Save PDF" to open your browser's print dialog, then select "Save as PDF" as the printer destination. This works in Chrome, Firefox, Safari, and Edge without any plugins or additional software.
Does this tool support Korean tax invoices (세금계산서)?
Yes. When the tool is in Korean mode, the printed document is labeled "세금계산서 (INVOICE)" and uses the standard Korean layout with supplier (공급자) and receiver (공급받는자) sections. The business registration number field accommodates the standard Korean 10-digit format.
Is there a limit to the number of line items?
No. You can add as many line items as needed by clicking the "+ Add Item" button. Each item has a name, quantity, and unit price. The subtotal is recalculated instantly each time you add, remove, or modify a line.
Can I set a custom tax rate?
Yes. The tax rate field defaults to 10% (standard Korean VAT), but you can change it to any percentage. The tool will recalculate the tax amount and total automatically. For zero-rated or exempt invoices, simply set the rate to 0.
Are my invoice details saved between sessions?
No. The tool does not use any local storage or cookies to persist data. If you close the browser tab, your data will be gone. To keep a record, always print or save as PDF before closing, or copy the relevant information elsewhere.
Can I use this for international invoices in currencies other than Korean Won?
The tool is primarily designed for Korean-format invoices with amounts displayed in Korean Won (원). In English mode, the currency display is adjusted, but the underlying amounts are unit-less. For formal international invoicing in specific foreign currencies, you may want to use a dedicated accounting platform.
Is this invoice legally valid in Korea?
This tool generates a printable invoice document but is not an official electronic tax invoice (전자세금계산서) as required for VAT-registered businesses in Korea. Registered businesses must issue electronic tax invoices through the National Tax Service system. This tool is best used for simple payment requests, pro-forma invoices, or informal billing between parties.
Can I customize the invoice with a logo or additional branding?
The current version does not support logo uploads or custom branding. The output is a clean, minimal invoice layout. For branded invoices, you can save the PDF and then add your logo using a PDF editor, or print the invoice on pre-printed letterhead.
