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.

Very responsive and fast customer service team. App works great and we will keep using it for the long term. It is pretty much complicated what it does, but happy to see how great it works.

The App works as it should. But the Support is stellar! I have been in contact with them due to various very specific issues and they were not only kind and helpful but also incredibly fast.
This made using the App an absolute pleasure.
