- Choose a currency label.
- Edit the fictional example or clear the items.
- Review rounded line amounts and copy the subtotal.
Unit labels describe the charging basis; they do not add a multiplier. Ten 50 kg bags priced per bag use quantity 10, not 500. The worked example is fictional: 2 × 350 + 1 × 180 + 1 × 120 = 1,000 before any applicable tax.
Quantities support up to 3 decimal places. Rates use the currency’s minor units: JPY 0, KWD 3, others 2. Each line rounds half up before the subtotal is added.
Subtotal before any applicable tax
Use this subtotal to plan your invoice. Apply the appropriate tax separately and enter all rates in your selected currency.
