Such a GameChanger app for our revenue, Consumer Electronics its 1 digit war and this app and support is the right way to fight it

So far I'm really pleased with this app. Its adding the US tariff fee at the checkout so I don't need to add it onto shipping. I'm not that tech savvy, so the support (Maggie) has been super helpful and patient with some issues I had.

We’ve been using the Upcharge app and it has worked exactly as we needed. I had a few issues with the initial configuration, but Angie and Evgeniya were incredibly helpful in getting everything resolved straight away. Their support was prompt, clear, and genuinely above and beyond. The app itself runs smoothly and does exactly what it promises, but what really stands out is the level of service behind it. Knowing that there’s such a responsive and capable team available makes a huge difference. Highly recommend both the app and the wonderful team behind it.

I don't normally leave reviews but these guys went way above and beyond to help me so I couldn't not! The app has been a lifesaver in being able to charge the US tariff fees that I'm now having to pay when shipping goods there. Despite watching all the helpful videos I was still stuck, so they went in and changed the necessary settings for me. Not only that but they replied several times to my initial struggles on a Sunday, which I absolutely wasn't expecting at all! Very very helpful people, highly recommend!

This app is amazing! It’s super fast and intuitive, and the support team is incredibly responsive. Any question I’ve had was answered quickly and clearly. Their help makes using the app completely stress-free. Highly recommend!

This app is perfect for the new US tariffs. It was pretty easy to set up especially with the great tech support I received to make sure it was all working correctly.

Extremely responsive support, friendly and helpful! This is how all apps should be, cannot fault their team.

Doesn't meet my requirements of adding specific product tariff % increase based upon the products country of manufacture.

This app made it simple to add extra fees to specific products without complicated workarounds. Whether it’s handling special packaging, customization costs, or other surcharges, it integrates seamlessly into the checkout process. The setup was quick, the interface is straightforward, and everything works exactly as described. A must-have if you need flexible fee management on your store.

App is easy to install and to configure. Evgeniya also took her time to help me customize the app for my theme and my specific needs. Can't reccomend enough

Been testing this tool for a week now due to the newly implemented tariffs in the US market. Support from the tech has been pro-active and very responsive!

Really great app! We use it to add mandatory fees to orders and everything works perfectly. We’re on the Dawn theme and had no issues with the installation. We can honestly recommend this app. Update: their support team is amazing!

App is great and more functional than others that we have used that didn't always work (e.g. product limits). Support was great on fixing an issue (that was self inflicted!). Would recommend

Maggie is absolutely amazing at her customer support! We spoke very briefly about our issue and she was off and running making the necessary corrections to get our business back up and running in no time! I love a product that has a team of technicians behind them to help you at any time. Maggie deserves a raise!!! She found our issue very quickly and even made a helpful suggestion to improve our operating efficiency! Love love love this app & its support team. Well done...A+++!

This app is exactly what we needed. Installation was a breeze, and their support team is amazing, they helped us resolve a design issue in under an hour. The app is super powerful and handles complex use cases like tariffs and additional product add-ons perfectly. Highly recommended if you're looking for a reliable, flexible solution.

Maggie & the team at Mageworks are always so helpful! I love this app and so appreciate the great customer service they provide.

This app was a a godsend with the introduction of tariffs on the products we sell into the United States. It took a little configuring and working with tech support to get it working how we needed but we're really happy with the result. I'm not sure what we would be doing now if it wasn't for this app. Their customer service is really responsive and helpful as well.

Bardzo dobra aplikacja. Używamy jej do dodawania obowiązkowych opłat do zamówień i wszystko działa bez zarzutu. Korzystamy z motywu Dawn i nie mieliśmy żadnych problemów z instalacją. Z pełnym przekonaniem możemy polecić tę aplikację.

Really solid app — setup was simple and didn’t take much time. We used it to add import tariffs, and it worked just the way we needed. Didn’t even have to reach out to support. We’ll see how it goes over time, but so far, it’s been great.

We needed this app for a particular use case to charge shipping on products that are certain marked in the backend as "don't require shipping" for technical reasons. So far it works really well and support has been super helpful and responsive with customizing the look and feel, answering questions and resolving any issues along the way
