Invoice Generator

The order of discount and tax matters more than it looks. Tax is charged on what the customer actually pays, so the discount must come off first — taxing the full amount and then discounting the total overcharges them and misstates the tax you owe. Two practical habits save trouble later: number invoices sequentially, because most tax authorities require an unbroken series, and state payment terms explicitly. “Payment within 30 days” with a due date on the document is far more collectable than an unstated assumption, and it is the single easiest change that gets freelancers paid faster.

Each line total is quantity × unit price. The subtotal is the sum of those lines. The discount is taken off the subtotal first, tax is charged on the discounted amount, and shipping is added afterwards: total = (subtotal − discount) + tax + shipping.

This produces a document; it does not track payments, send reminders, store client records or handle recurring billing. There is no logo upload, and the PDF uses a standard font set, so characters outside the Western European range are stripped rather than rendered. Invoice requirements differ by country — many require a sequential number, your registered address and a tax registration number — so check your local rules before sending.

Three lines totalling 3,765 with 20% VAT produce 753 of tax and a total due of 4,518. Apply a 10% discount first and the taxable amount falls to 3,388.50, giving 677.70 tax and 4,066.20 due.

4. Check the totals on screen, then download the PDF.

• Applying tax before the discount, which overcharges the client.
• Reusing or skipping invoice numbers, which breaks the required sequence.
• Leaving off a due date, so “when you can” becomes the payment term.
• Omitting a tax registration number where your country requires one.

The Invoice Generator builds a professional invoice from your line items and downloads it as a print-ready A4 PDF. It handles quantities, unit prices, a percentage discount, tax and shipping, and shows the running totals on screen before you export.
