How it works

• Applies Add Charge using a Draft Order approach.
• Add Charge can be set as a percentage (%).
• Does not create an actual product in your Shopify store.

Known limitations

• Discount behavior is not fully compatible, so stores may rely on a manual discount input box/workaround.
• Dynamic checkout buttons do not work with this version.

• When customers select an Add Charge option, the corresponding Add Charge product/variant is added to cart alongside the main product.

What it supports

Compatibility notes
