Free Invoice Generator - Professional Invoices for Freelancers

What Is Invoice Generator?

An invoice generator creates professional invoices with your business details, client information, line items, tax calculations and payment terms. Invoicing is a critical business process — it is how you request payment for goods or services provided. A professional-looking invoice builds credibility, ensures clarity about what is owed and provides documentation for accounting and tax purposes.

This tool creates clean, well-formatted invoices that include all legally required information for UK businesses: your business name and address, client details, invoice number, date, itemised services or products, VAT if applicable, and payment terms.

Basic invoicing with line items, an auto-generated invoice number and a VAT number field is free. Premium adds tax calculations, multiple currencies, a payment terms selector, a free-text notes field, a saved client list, invoice history (save and reload past invoices) and a PDF export via your browser's print dialog.

How to Use This Tool

1. Enter your business details: name, address, email and optional VAT number.
2. Enter the client's details: name, company and address.
3. Add line items with descriptions, quantities and unit prices.
4. Premium: set the tax rate (VAT) and payment terms (Net 30, Net 60, etc.), save the client to your list, and save the invoice to your history.
5. Preview the invoice, then copy it as text or, with Premium, export it as a PDF.

Tips & Best Practices

• Use sequential invoice numbers (INV-001, INV-002) — this is a legal requirement in many jurisdictions.
• Include clear payment terms — "Net 30" means payment within 30 days of the invoice date.
• Add your bank details or payment link to the invoice to make payment as easy as possible.
• Keep copies of all invoices for at least 6 years for tax records (UK HMRC requirement).

Common Use Cases

• Freelancers and contractors billing clients for completed work.
• Small businesses creating professional invoices without accounting software.
• One-off invoicing for side projects, consulting or services.
• Creating invoice templates for recurring billing.
