How the total is built
Quantity times rate gives the subtotal. Any discount comes off that figure first, and tax is charged on what is left — that ordering matters, because taxing before discounting produces a different (and usually wrong) number. The result is the amount your client owes.
A real invoice usually has several lines at different rates. Add them all up and the same sequence applies: sum the lines, subtract the discount, apply tax to the remainder.
A note on tax rates
Whether you charge tax at all, and at what rate, depends on where you are registered and what you sell. Enter the rate that applies to you — we don't guess one for you, and nothing here is tax advice.
Turn it into an invoice
The invoice generator runs the same arithmetic across as many lines as you need and downloads the result as a PDF. If the work hasn't been agreed yet, start with the quote generator instead.
