To create add-on items:
- Select the category for add-on items.
- Create the required add-on item.
- Enter the name, price, and a short description.
- Save the item so that it can be linked to main items.

After creating the main item and its add-on items, define which extras should be available for the main item.
- Open the main item you want to edit.
- Scroll to the add-on item section.
- Select the add-on items that should be available for this main item.
- Save the changes to activate the options in the order process.
Order Overview at the Table
After an order has been entered, the GastoZack app shows an overview for the table.
The overview displays all ordered items, including the main items and selected add-ons. This helps staff check the order before processing it and reduces misunderstandings during preparation.


Example Receipt
The receipt summarizes the order details. It contains all ordered main items and the selected extras.
Example order:
- 1 cappuccino, regular.
- 1 cappuccino with oat milk.
- 1 cappuccino with almond milk.
The receipt helps service staff deliver the order correctly and efficiently.
