# Percent discount

This walkthrough configures a percent discount on a line item and checks the result against a few months of usage.

## Step 1: Decide the percentage

Pick the flat percentage to take off the gross bill amount on this line item. For this walkthrough, we'll use 20%.

Set:

* `value`: 20 (20%)

## Step 2: Add a label

Set a label for how this discount should appear on the customer's invoice line, for example "Loyalty discount."

## Step 3: Set the order, if stacking with other discounts

If this line item has other discounts configured too, set the `order` field to control the sequence they apply in. The recommended order across discount types is quantity discount first, then fixed discount, then percent discount.

## Step 4: Save and preview

Save the line item configuration, then use invoice preview to confirm the numbers. Walking through a few months of usage against the configuration above:

```
Month 1: Bill=$4,000. 20% off → Invoice: $3,200.
Month 2: Bill=$1,500. 20% off → Invoice: $1,200.
Month 3: Bill=$3,000. 20% off → Invoice: $2,400.
```
