# Percent discount

## How to set up a percent discount

1. On the line item, add a percent discount.
2. Set `value` to the percentage to take off the gross bill (for example, 20 for 20%).
3. Optionally set a `label` for how the discount appears on the invoice.
4. Save. The discount will now apply at the same rate to every billing period, scaling automatically with the bill.

## How to stack a percent discount with other discount types

1. Add each discount to the line item — for example, a quantity discount and a percent discount.
2. Set the `order` field on each to control the sequence they're applied in.
3. Use the recommended order — quantity discount first, then fixed discount, then percent discount — unless you have a specific reason to deviate. Quantity discount reduces units before any pricing model runs; fixed and percent discounts both operate on the resulting dollar amount.
4. Save and preview to confirm the combined result.

## How to read the invoice breakdown for a percent discount

1. Open the invoice and find the percent discount line.
2. Each period's breakdown record includes: the amount before and after the discount, the discount applied, and the percentage used.
3. Use this breakdown to verify the discount matches the expected calculation.
