Free Online Invoice Generator (PDF) – Free Online Invoice & Quotation Generator

If you invoice clients regularly, you need a simple workflow that produces clean, accurate documents every time. This free online invoice generator is designed to help freelancers, small businesses, and agencies create client-ready invoices without setup time or complicated software. You can add your company details, client information, line items, and totals with live preview so you always know what your PDF will look like before you send it.

Unlike tools that require an account, Quick Invoice Tool works with no signup required. You can start immediately, generate a PDF invoice, and share it with a client by email or messaging. The generator supports common billing needs including taxes, discounts, and service charges. If your invoice includes payment status tracking, you can also show paid, partial, or balance due information depending on what you’ve received.

Privacy matters when you’re handling client names, addresses, and payment details. That’s why this tool is built to run in the browser and keep documents on your device by default. You stay in control of your data while still getting a modern experience with templates, instant calculations, and quick PDF export.

An invoice is typically sent after goods are delivered or services are completed. If you need approval first, start with a quotation (estimate) and then invoice once the work is confirmed. Many users treat Quick Invoice Tool as a Free Online Invoice & Quotation Generator: one place to generate both documents online and export consistent PDFs.

Invoice checklist

• Invoice number + issue date (and due date if you use one)
• Your business details and the client’s billing details
• Itemized line items with quantities, rates, and clear descriptions
• Subtotal, taxes/discounts, and the final amount due
• Payment instructions and optional notes/terms

Tips to get paid faster

The best invoice is easy to understand and easy to pay. Use specific line-item descriptions, include a clear due date if you set payment terms (net 7 / net 14), and add payment instructions prominently so clients don’t have to ask. If you work on milestones, you can invoice per phase and keep the balance due visible.

Consistency matters too. Using the same templates and layout across invoices and quotations builds trust and reduces confusion—especially when a client forwards your PDF internally.

If you bill internationally, double-check currency formatting and tax naming (VAT/GST/sales tax). A clear, consistent PDF reduces follow-up questions and makes your invoice feel more professional, which can help shorten the time between sending and payment.

Need an estimate first? Use the free quotation generator to send a quote, then come back to issue the invoice when the work is approved.
