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.

Good app, it allows me to add the fees for tariff collection for US based customers and functions as needed. Support has always resolved issues in a timely manner and has always responded to all support requests through their chat feature.

The app itself does exactly what we need it to do and at a reasonable price. We did have a bug with the app but customer support were quick to respond to our message, explain what the issue was in detail and resolved it very quickly.

The app stopped working for me (user error due to a theme update) and Zia from support was very helpful in getting it back up and running for me. It's very helpful being able to customize fees so thoroughly, especially with the headache of tariff fees being introduced. Very useful app and good customer support.

The team was extremely helpful when the app wasn’t working as intended and kindly provided a refund for the period when we experienced the issue. Everything is now working as it should for our store, and we’re very happy with the app!

We have had this app on our store for some time and while it always gave us a good service working around the Shopify shortcomings, at some point some fees would just not show anymore.
After talking to the support team found out that a new system was in place, cleaner, more effective and it was just a matter of creating the fees again.

Special thanks to Javid who guided us thru the changes needed and was able to sort all of our issues promptly
