How to Add Modifiers with a Cost in Shopify

When managing a restaurant, you may offer modifiers (such as toppings) that are either free or come with an additional cost. For example, toppings like lettuce, pickles, and onions might be free, while extra cheese or bacon could incur an extra charge.

Follow the steps below to add a modifier with a cost:

• Go to Products within Shopify
• Create a Product for the modifier (e.g., Extra Cheese or Bacon).

• Add a Title for the modifier (e.g., "Extra Cheese").
• Add a Description for the modifier to explain what it is (e.g., "Add a slice of cheese to your burger").
• Add Media (optional) to show an image of the modifier if desired.
• Add Price: Enter the price as the extra cost for adding this modifier (e.g., $1.50).
• Charge Tax: Enable this option if applicable (based on your location and tax rules).
• Inventory & Shipping: These options are not active in the Kitchen Kit app, so whether they are checked off or not will have no impact.
• Click Save to finalize your changes.

• Go to the Kitchen Kit App.
• Click on Menu Management.
• Click on Menu Items to view and manage the items on your menu.

Click on Create Menu Item to add the modifier as a menu item.

• Add a Menu Line Item Title: Enter a title for the modifier (e.g., "Extra Cheese").
• Click on Link Product to associate the modifier with the product.
• Click on the Newly Added Product

• Click Select
• Click Save

After adding a new product to Shopify and syncing it to the Kitchen Kit app, the next step is to assign it to the appropriate modifier categories. Follow the steps below to complete this process:

• Click on Modifiers under Menu Management to manage your modifier categories.
• Click on the Modifier that you would like to add the new extra cost modifier to.

• Click on Add Value to add a new modifier option.
• Give the Value a Title: Enter a title for the modifier (e.g., "Extra Cheese").
• Check Off Default Selection: If you want this modifier to be selected by default, check off the "Default" box.
• Adjust Quantity Options: Set the quantity options as needed for the modifier (e.g., 1, 2, or 3 slices of cheese).

• Click on Link Variant: To link a specific variant to the modifier, click on "Link Variant".
• Check Off the Product: Find the product (e.g., Extra Cheese) and check it off.

• Add a Discount Type: If applicable, select a discount type (e.g., Percentage or Fixed Amount).
• Add Discount: Enter the discount amount or percentage if a discount applies to the modifier.
• Click Save: After making all necessary adjustments, click Save to finalize the new modifier with its associated discount.

When viewing modifiers within a modifier category, you'll see both free modifiers and those that come with a cost.
