Discounts and taxes on orders

You can adjust a sales order’s total with discounts and tax. Fiddle applies them in a set order so the math stays predictable.

Discounts

Discounts can be applied at two levels:

• Line discount — reduces a single line item, as a percentage or a fixed amount.
• Order discount — reduces the order subtotal after all lines are added.

1. Open the sales order.
2. To discount a line, enter the percentage or amount in the line’s Discount field.
3. To discount the whole order, set the Order discount in the totals panel.

Taxes

Tax is calculated on the discounted subtotal, so discounts always come first.

1. Choose a tax rate for the order, or let the customer’s default rate apply.
2. Lines marked tax-exempt are excluded from the calculation.
3. The tax amount appears as its own line in the totals.

The calculation order is: line discounts → order discount → tax. Tax is never charged on the discounted-away amount.
