What is Invoice Generator?

An invoice generator helps freelancers, small businesses, and contractors create professional invoices quickly and for free. Instead of using expensive accounting software or struggling with Word templates, you can fill in your details and have a print-ready invoice in seconds. Our generator supports multiple line items with quantity and rate, automatic subtotal calculation, percentage-based tax and discounts, custom notes/terms, and multi-currency support (USD, GBP, EUR, INR). The invoice is generated entirely in your browser — no data is stored or sent to any server.

How It Works

Fill in your business details (From), client details (Bill To), invoice number, dates, and line items. Add as many line items as needed with description, quantity, and rate — amounts are calculated automatically. Set optional tax rate and discount percentage. Click "Print / Save as PDF" to open a cleanly formatted invoice in a new window for printing or saving.

Formula

Line Amount = Quantity × Rate
Subtotal = Sum of all Line Amounts
Discount = Subtotal × (Discount% / 100)
Tax = (Subtotal − Discount) × (Tax% / 100)
Total = Subtotal − Discount + Tax

Formula Explained

Each line item amount is the product of quantity and unit rate. The subtotal sums all line items. Discount is applied as a percentage of the subtotal. Tax is calculated on the amount after discount (this is the standard method in most jurisdictions). The total due is the final amount the client needs to pay.

Example

Line Items: Web Design: 40 hrs × $85 = $3,400.00 Logo Design: 1 × $500 = $500.00 Hosting Setup: 1 × $150 = $150.00 Subtotal: $4,050.00 Discount (10%): -$405.00 Tax (8%): $291.60 Total Due: $3,936.60
