See every featureAvonix lets you apply tariffs, surcharges, and customer opt-in environmental fees to your Shopify checkout — all from a single app. Start from a template (eco, tariff), target fees by country or state, and let customers add carbon offsets at checkout. Tariffs apply when shipping to matching countries.
Feesly adds extra charges to your orders: credit card surcharge, service charge, handling or processing fee, convenience fee, bag fee, bottle deposit. On POS: apply a fee with one tap from the smart grid, or let your default fee apply automatically. On your Online Store: attach the fee to products (any theme supported) or add one fee line per order. Fixed or percentage, taxable or not.
