Add cart fees & surcharges your way. Customers opt-in. You keep all the revenue.
Add any cart fee—handling, rush processing, shipping protection, gift wrap, or custom surcharges. Customers opt-in with a clean toggle widget before checkout. Unlike shipping protection apps, TackOn works for ANY fee type. You keep all collected fees with no revenue sharing. Fully customize the widget to match your brand with colors, text, and CSS. Works with all Online Store 2.0 themes. Setup takes just minutes with no coding required.
- Add fixed, percentage, or combined fee types to any cart
- Create product-specific surcharge rules with flexible conditions
- Multi-currency support through Shopify Markets integration
- Clean install/uninstall using theme app extensions
