Taxes, VAT and discounts
Multiple tax rates, inclusive prices, zero-rated and exempt items, discounts.
Every line can have its own tax: choose Standard (with a rate), Zero rated, Exempt or No tax. Lines with the same rate are grouped in the tax breakdown.
Inclusive or exclusive
If your prices already include tax, switch the tax mode to "Prices include tax". The tax inside the price is shown separately.
Discounts
Give a discount on a single line (percent or fixed amount) or on the whole document. A document discount is spread across the lines before tax is calculated, so the tax is always charged on the discounted amount.
