What merchants think

Feedback submitted

Merchants say this app is great for adding flexible surcharges and fees at checkout, like rush service, packaging, shipping insurance, local taxes, deposits, and complex tariffs or import duties. They find setup easy, the interface intuitive, and fees reliably applied by product, cart, or destination. Many highlight fast, knowledgeable support that helps with custom code, advanced configurations, and theme-related fixes, making it a long-term solution.

Another great service experience with UC Lab! My cart page became glitchy after a Shopify update and Javid told me exactly how to fix it. I highly recommend this app!
