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.

The service for this app is outstanding. We had an issue with how the charge was being displayed to the customer and within a day they had it fixed and looking just how we wanted it to.

No one is helping me. I have sent two emails. The app is activated but the shopping cart shows nothing. The app does not do anything. Be aware of scam.

We are sincerely sorry for the delay in response and the frustration this has caused. We take your feedback seriously and can assure you that this is not a scam; it’s likely a theme integration issue that can be fixed in minutes. We are looking forward to having you back to resolve your issue as soon as possible

Support is excellent and highly responsive, but truly the app is a bit quirky. If you use a hidden fee that is % based, your customers may see an extremely high amount of products in their cart, which I think will really hurt conversions.

We use this to add extra shipping fees for split shipments (we have a lot of pre-orders mixed with in-stock items). It works great, and we've been super impressed with their customer service. They helped fix some things on our cart so the app would work better and did a fantastic job!

This app doesn't look very good in the shopping cart. It also duplicates and generates its own products, so thats a mess. It also adds its own filters to your collections, also a mess.

Does exactly what it is supposed to do. I had one small problem with the surcharge not being required for certain people, but their team fixed it promptly. Thank you!

Just installed the App. Appears to work for our online store, but not the Shopify POS. Waiting to see if they are able to fix. Until then, a little disappointing.

It’s essential for the U.S. tariffs. When I was having trouble with the app, their support was amazing. Thank you, Angie and Evgeniya! Don’t hesitate to reach out to the team—they’re incredibly kind and helpful.

One pro tip from me: when testing the app, make sure to select your own country as well, not just the U.S. It should work properly then. If something doesn’t show up, it’s likely due to your IP address.

Good luck!

We’re really glad to hear that the app is helping you with U.S. tariffs and that our support was helpful when you ran into trouble. It truly means a lot that you took the time to highlight that.

Also, huge thanks for sharing your pro tip about testing with your own country selected and keeping IP in mind - that’s very valuable advice for other merchants who might be setting things up for the first time.

If you ever need anything else, please don’t hesitate to reach out. We’re always happy to help! 🙌

Not recommended this app. The app cannot fulfill what I need and customer service representative agreed about that. After that, I uninstalled it and still charged me 9.99 even within 14 days free trail. I don't know why!!!

Hello,

It looks like you initially installed and activated the app’s free trial back in June 2023. Since the trial period is only available once, it had already expired by the time you reactivated the app on April 26, 2025.
As a result, when you approved the app charge on that date, it automatically started a paid subscription without a new trial period.

We've gone ahead and issued a refund for the latest app charge invoiced on May 4, 2025 for the billing period Apr 26, 2025 – May 26, 2025 on May 5, 2025.
The amount should be back to the source account as per the bank's processing timelines.

Please let us know if there is anything else we may assist you with.
