In SuiteCommerce InStore (SCIS), store managers and sales associates can override the subtotal of an order. The price override capability allows you to increase the amount of the order. There is no additional configuration required from administrators to support price override capability.
To apply a price override or markup in SCIS, the sales associate clicks on the amount in the line-item in the cart or the order subtotal. He or she can then use the custom discount dialog to increase the amount. For more information, read Applying a Markup or Price Override.
