What this tool does
The Invoice Generator creates professional PDF invoices directly in your browser. You enter your business details, client information, and line items with quantities and unit prices, and the tool generates a clean, formatted invoice ready for download. Everything runs client-side, meaning your financial data never leaves your device. The generated PDF includes your company name, address, email, and phone number, along with the client's name, address, and email. It handles invoice numbering automatically, tracks invoice dates and due dates, and supports multiple payment terms including Due on Receipt, Net 15, Net 30, and Net 60. You can choose from five currencies: USD, EUR, GBP, CAD, and AUD. Tax rates and fixed discounts are applied automatically to the totals. An optional notes field lets you include payment instructions or terms of service. The result is a professional invoice PDF that downloads instantly to your device.
How it calculates
**Line Item Total:** \`\`\` Line Total = Quantity x Unit Price \`\`\`
**Subtotal:** \`\`\` Subtotal = Sum of all Line Totals \`\`\`
**Tax:** \`\`\` Tax Amount = Subtotal x (Tax Rate / 100) \`\`\`
**Total:** \`\`\` Total = Subtotal + Tax Amount - Discount \`\`\`
**Where:** - **Quantity** = Number of units for each line item - **Unit Price** = Cost per individual unit - **Tax Rate** = Percentage applied to the subtotal (e.g., enter 10 for 10%) - **Discount** = Fixed dollar amount subtracted from the final total
**Example:** You have two line items: 5 hours of consulting at \$150/hour (\$750) and 10 product units at \$25 each (\$250). The subtotal is \$1,000. With a 10% tax rate, tax is \$100. With a \$50 discount, the total is \$1,000 + \$100 - \$50 = \$1,050.
Who should use this
- **Freelancers and consultants** who need to bill clients for hourly or project-based work without investing in accounting software - **Small business owners** who send occasional invoices and want a quick, free solution without monthly subscription fees - **Independent contractors** who need professional-looking invoices for tax documentation and client billing - **Side project operators** who do occasional paid work and need a simple way to create invoices - **Students and interns** doing contract work who need to invoice for the first time and want a straightforward tool
Worked examples
**Example 1: Freelance Web Developer** A developer bills a client for a website project. Line items: Website Design (1 unit at \$2,500 = \$2,500), Frontend Development (40 hours at \$100/hour = \$4,000), and Hosting Setup (1 unit at \$200 = \$200). Subtotal: \$6,700. Tax rate: 0% (services in a tax-exempt jurisdiction). No discount. Total: \$6,700.
**Example 2: Small Catering Business** A caterer invoices for an event. Line items: Appetizer Platters (5 at \$75 = \$375), Main Course Servings (50 at \$25 = \$1,250), Dessert Trays (3 at \$60 = \$180), and Event Staff (4 at \$200 = \$800). Subtotal: \$2,605. Tax rate: 8.5%, so tax is \$221.43. Early payment discount of \$100. Total: \$2,605 + \$221.43 - \$100 = \$2,726.43.
**Example 3: Photography Session** A photographer invoices a portrait client. Line items: Portrait Session (2 hours at \$250/hour = \$500), Photo Editing (20 photos at \$15 each = \$300), and Printed Album (1 at \$150 = \$150). Subtotal: \$950. Tax rate: 7%, so tax is \$66.50. No discount. Total: \$1,016.50.
Limitations
This tool generates one-time invoices and does not support recurring invoice schedules or automatic payment reminders. It does not integrate with payment processors like Stripe or PayPal, so clients cannot pay directly from the invoice. The tool does not track payment status or maintain a history of past invoices since all processing happens in the browser with no server-side storage. Company logos cannot be added to the PDF at this time. The invoice uses a single tax rate applied to the entire subtotal and does not support per-item tax rates. Currency conversion between different currencies is not supported. The PDF layout uses a standard professional template and cannot be customized with different fonts, colors, or layouts.

Q: What currencies are supported? A: The tool supports USD (\$), EUR, GBP, CAD (C\$), and AUD (A\$). Select your currency from the dropdown and all amounts will display with the appropriate symbol.
