# Adjust a price at the register

> Apply an SKU-preserving price adjustment from the POS price-adjustment tile or a cart line item action.

# Adjust a price at the register

## What does this do for me?

Price adjustment lowers the unit price of a cart line without changing the SKU, so your inventory and reporting stay accurate. It is decrease-only: the new price cannot exceed the original price.

## 1. Open the adjustment

1. On the POS Smart Grid, select the **Price Adjustment** tile. Its subheading reads **Lower line price** when it is available.
2. You can also open the same form from a cart line's action menu with **Adjust line price**.

If the tile is not available, the feature is disabled for the location or your user is not assigned to it.

## 2. Select the cart line

1. Under **Select a cart line**, choose the line you want to change.
2. If the modal was opened from a line item, that line is preselected and the **New unit price** field is filled with its current price.

A line that already carries a discount cannot be adjusted, because removing the discount later would also clear a promotion that was already there.

## 3. Enter the new price

1. In **New unit price**, enter a price of 0 or more. It must not exceed the current price, and it cannot have more decimal places than the cart currency allows.
2. In **Reason**, optionally enter why the price changed. The reason is saved with the action and used as the discount label.
3. Select **Apply price adjustment**.

## 4. Confirm the result

A success banner reads **Adjusted** followed by the line and the applied unit price. If the app cannot confirm the adjustment with Shopify POS, check the line before retrying.

Every applied adjustment writes a **PRICE\_EDIT** event to the audit log, including the SKU, the old and new unit price, the quantity, and the reason.
