How to Change an Item or Modifier Quantity

For cashiers and servers who need to set the quantity of a menu item or an added modifier before sending the order.

Before you start: Open an in-progress order. The item must be available on the menu; modifier controls appear only after you choose an item, and any required size or modifier selections.

Change an item quantity

Open the required category, then locate the menu item.
Press and hold the item. The Qty selector opens.
Tap + or − until the displayed quantity is correct, then tap the purple check mark to apply it. Complete any size or modifier choices that follow. The item row in the order shows the new quantity and updated amount.

Change an item quantity from the cart

After the item has been added, tap its quantity box at the left of the item row. The numeric soft keyboard opens.
Enter the new whole-number quantity, then tap the keyboard check mark (Done). The cart updates the item amount and order totals.

Important: Enter a quantity greater than zero. SalsaPOS rejects zero, a leading zero, or non-numeric input and restores the previous quantity.

Change a modifier quantity

With the item open, select its size if prompted. On the modifier screen, tap the modifier you need, such as Extra Cheese.
Press and hold the selected modifier. In the Qty selector, use + or −, then tap the purple check mark to save the modifier quantity.
Tap the purple check mark on the modifier screen to finish the item configuration. Confirm the modifier line and the order total before sending the order.

Expected result

The cart displays the item quantity, modifier quantity, and recalculated amounts. For example, a modifier quantity of 2X appears on the modifier line.

Common issues

The quantity selector does not open: Press and hold the item or modifier, rather than tapping it once. A normal tap selects the item or modifier.
The minus button does not reduce a modifier: A modifier cannot be reduced below the quantity of its parent item. Reduce the item quantity first if that is required.
There are no modifiers: The selected item may not have modifiers, or a size may need to be selected before modifier options appear.
The quantity will not save: Make sure the order is still in progress and finish with the purple check mark, not the close button.
The cart quantity field restores its old value: Enter a whole number greater than zero, then tap the keyboard check mark (Done).

Note: Menu names, prices, sizes, and available modifiers are specific to the restaurant configuration. The screenshots use sample menu data from the connected POS terminal.
