What is Canteen?
Canteen is a Shopify app that automatically adds mandatory fees and deposits to your customers' orders. Whether you need to charge bottle deposits, environmental fees, container deposits, or any other mandatory surcharge — Canteen handles it on both your Online Store and Shopify POS.
How It Works
Canteen works by creating a special "Fee" product in your Shopify store. When a customer adds a product that matches one of your fee rules, Canteen automatically adds the corresponding fee as a line item in the cart.
Key Concepts
Rules — You define rules that determine which products get which fees. Rules can target specific products, variants, or entire collections.
Fee Product — Canteen creates a product called "Fee" in your store. Each rule creates a variant of this product. You can rename this product and change its image.
Automatic Calculation — On POS, fees are calculated automatically when products are added to the cart. On your Online Store, the app embed handles it.
Where Fees Appear
Cart page: Fees appear as a line item in the cart alongside your products
Checkout page: Fees carry through to checkout as a line item (Shopify controls the checkout layout)
POS: Fees appear in the cart and are calculated automatically via the Canteen tile
