Total Due
How It Works
An invoice is a request for payment, and a good one leaves nothing to guess: who is billing, who is paying, what was done, and exactly how much is owed. This generator builds that document for you. Enter your business details and your client's details, add a line for each product or service with its quantity and unit price, and the totals work themselves out — subtotal, discount, tax, and the final amount due.
The math follows the standard order: the discount comes off the subtotal first, then tax is charged on the discounted amount. Every figure is calculated in whole cents, so the totals always add up exactly, with no rounding drift between the line items and the final total. The invoice preview updates as you type, and the print button saves it as a clean PDF you can email to your client.
Worked Example
A freelance designer bills a client for 2 hours of design work at $50 an hour and 1 hour of consulting at $25. The subtotal is $125.00. With no discount and 10% tax, the tax comes to $12.50 and the total due is $137.50. If she offers a 10% discount instead, the discount is $12.50, the taxable amount drops to $112.50, the tax becomes $11.25, and the total due is $123.75.
How to Use This Tool
Fill in your business name and address, then your client's name and address, and give the invoice a number and date — the number defaults to INV-001 and the date to today. Add a row for each item, with a description, quantity and unit price; use + Add Item for more rows and the × button to remove one. Set a discount and tax percentage if they apply, and the preview below updates instantly. When it looks right, click Print / Save as PDF.
Tips and Practical Advice
Number your invoices in sequence and never reuse a number — it keeps your records clean and makes it easy to chase a late payment by reference. Write line descriptions your client will recognize, like "Website homepage design — 2 hours" instead of just "Work," so there is nothing to argue about later. And send the invoice the same day the work is done: invoices sent promptly get paid faster than ones that sit in a drawer for a week.
