Kai lets you add any fee to your cart and checkout with no code. Create mandatory fees such as tariff surcharges, small order fees and handling fees that apply automatically, or optional add-ons such as gift wrapping, shipping protection and eco packaging that shoppers choose with a checkbox, toggle or popup. Add a fixed amount or a percentage per order or per product, and target all products, collections or specific items. Fees show in local currency and can be limited by market.

• Mandatory fees or optional add-ons shown as a checkbox, toggle or popup
• Fixed or percentage fees per order or per product, with cart value rules
• Apply fees to all products, specific collections or individual products
• Market-based tariffs and fees shown in each shopper's local currency
• Fee revenue dashboard with orders with fees and per-fee performance

ShipEase gives you custom shipping rates and shipping rules in one app. Set rates by product, weight, dimensions, cart total, zip code or postcode, or show live rates from your own carrier account with markups. Blend rates for mixed carts. Hide, rename or reorder shipping methods at checkout using cart, product, customer, B2B and address conditions. Test every change on your real checkout first. Custom rates need carrier-calculated shipping (CCS); checkout customizations work on every store.

• Custom shipping rates by product, weight, cart total, zip code and postcode
• Hide, rename and reorder checkout shipping methods, no CCS needed
• Live rates from your own FedEx, UPS, USPS, DHL, Canada Post or AusPost account
• Cart-value thresholds, tiered, per-item and per-kg rates, rate blending
• Test rules on your real checkout and see why each rate shows or is hidden
