Applies to: Toast POS, Toast Web
Permissions needed:
What you'll accomplish: Apply a preconfigured discount to an item or a whole check on the POS, remove a discount, and resolve a discount that won't apply.
Note: An employee must have the 3.1 Discounts permission to apply the discounts described below. If an employee without that permission tries to apply a discount, they will be prompted to enter a manager passcode. Discounts themselves are created in Toast Web. To set them up, see Get Started With Discounts.
You can discount a single item directly from the ordering screen. There are two ways to do this, and both reach the same discount options.
Video overview of using discounts on the POS.
To discount an item using the Discount Item button:
For example, to take $3.00 off a $13.00 item, applying an open dollar discount of $3.00 shows as a 23.08% discount on the check.
If the discount requires a manager passcode, you are prompted to enter it. Otherwise, the discount applies and appears as a line item below the discounted item on the ordering screen.
To discount an item using the Discount button on the check:
Expected outcome: The discount appears as a line item directly below the discounted item on the ordering screen.
You can apply a discount to a whole check from the ordering screen.
If the discount requires a manager passcode, you are prompted to enter it. Otherwise, the discount applies and appears as a line item on the ordering screen.
Expected outcome: The discount appears on the check, and the check total updates to reflect it.
Note: Discounts apply to the pre-tax total. For example, if a check is discounted to $50 — whether through an item or a check discount — tax is then calculated on the $50 total.
To apply a discount to more than one item on the same check, use the Select Items option instead of discounting each item individually.
Expected outcome: The discount applies to each item you selected, and each shows the discount as a line item on the check.
Note: Whether two or more discounts can be combined on the same check is a configuration setting. To allow it, see the Apply Multiple Discounts section of Get Started With Discounts.
To remove a discount from an item, select the item that has the discount applied, then select the same Discount button on the right side of the screen. The discount disappears from the check.
Expected outcome: The discount line item is removed and the item returns to its original price.
To apply a discount after a payment has already been taken, see the Negative Balance is Due on a Check section of Get Help With Checks That Will Not Close on POS.
A discount applies as $0 or shows an "items included cannot be discounted" error when one or more items on the check are set to not be discountable. Each menu item has a Can be discounted? setting, and if it is set to No, a discount will not reduce that item's price. In Toast Web, navigate to Menus > Bulk management > Advanced properties, set Can be discounted? to Yes for the affected items, then save and publish. Resync the POS and apply the discount again.
Also asked as:
Applying a discount changes the tax because discounts apply to the pre-tax total, and tax is recalculated on the new, lower price. For example, if a $30 discount lowers a check, the tax is then calculated on the reduced total rather than the original amount. This is expected behavior. If you need to collect tax on the original full price, a post-tax discount must be configured in Toast Web — see the Create a Post-Tax Discount section of Get Started With Discounts.
Also asked as:
Whether you can apply more than one discount depends on how the discount is configured. By default, item-level discounts cannot be combined. To allow multiple discounts on a check, the discount must be set up to allow it in Toast Web. See the Apply Multiple Discounts section of Get Started With Discounts.
Also asked as:
A discount may not show up on the POS because it is inactive, outside its scheduled availability, or restricted by permission level. To find and fix the cause, see Troubleshoot Discount Availability. I think we should also add the discount may not populate because the a duplicate item with a different item number was added to the discount configuration then the item that is being wrung up on the pos.
