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.

App works perfectly and makes it so easy to offer up sell items along with gift wrapping for our customers. The support is beyond amazing! Every question and request was answered quickly, accurately and very professional. I would highly recommend this app to anyone running a store that needs to offer add-ons or up sells on their products.

Save your company some money and increase you probability. This app is great! I added in my packing material as part of my cost to customers, so I don't have to eat the cost. I had a little problem figuring out the software programing, but support was great! They sprang into action and not only fix my problem, but made the browser update better. What to go guys!! I would highly recommend this software to help off set some of you cost a pass it to the customer.

We had some issues with the theme we are on pulling incorrect data on the cart page and can say that the support team came through huge for us. They were able to get in and clean up the code/styling to fix the issue and get the app working sat 100%. Thank you to Angelika and her team for helping us out and fixing the issue we were running into!

We use this app to add a cart fee during checkout. It works quite well and the support team is super responsive! I wish there was a little more opportunity for customization (our cart fee needs more details to describe it and there is a strict character limit). The cart fees work by generating products, which can seem a little confusing on the backend, but the benefit is that the cart fee shows up everywhere we need it to (work orders, confirmations, etc.). Overall would recommend this for a solution to cart fees and we have definitely seen this app pay for itself with the increased revenue.

Exactly what I was looking for to charge processing fees on my Event Products. Includes the ability to easily add IF statements to narrow in the product types to charge fees on with control over how to display that fee to the customer. Thanks!

This app was a huge waste of time. They edited code on our theme and the app did not work properly. After we reverted to saved version it caused a lot of other problems which cost us 20+ hours to fix!! I would not recommend this app for the following reasons.

1. We were very clear about how we wanted a handling fee added to our website and was told it was possible. Once we downloaded the app and gave them access to our code they made changes and told us the fee was possible but not in the way we had wanted (after messaging with their support and confirming it was possible before giving them access to our code). I found this to be dishonest and an attempt by them to sell us the app instead of being honest upfront.

2. The app requires you to change the code of your store. This is the only app i have found that requires you to change code in your theme. Most professional apps are developed in a way that does not require this.

3. No live support. When the function did not work properly there was no way for us to reverse the changes, we had to wait for them to get on line and trust they would fix it. Only email back and forth after hours of waiting.

4. The handling fee function did not work the way they sold it to us. Orders under $50 were supposed to have $5 handling fee. We tested it multiple times adding items to the cart and removing items and the fee is not consistent. There were times the cart was over $50 and it would add the fee. There were times the cart was under $50 and it would not add the fee.

Unprofessional app and sold in dishonest way. If they only told us the app would not do exactly what we wanted it would have saved everyone time and one less negative review. Instead they were more concerned with getting another download and monthly fee.

Their 4.3 rating says a lot. After a lot of trial and error with shopify apps I won't be using any apps with less than 4.9 going forward.

We’re extremely sorry that you had to face such difficulties. We thoroughly investigated your ticket and please find our comments below.

1) Your initial request was to add a fee for all orders under a specific amount. The thing is that our app can do this without any issues. Please, take into account that Shopify doesn’t allow adding extra fees as a separate row in the checkout as you wanted. Our team didn’t make a promise to set it up this way.

2) Also, fees couldn’t be added without theme code modification due to Shopify API restrictions. Other top and popular apps require code modification as well. You can find a detailed description of how to make changes on Shopify App store listing. Also, we provide installation and uninstallation services free of charge for all customers.

3) Besides contact email we have live chat support. You can find the live chat icon in the right bottom corner of the screen.

4) After reviewing your ticket we’ve found out that when we installed the app, the modal cart was disabled in your store. Then it seems someone on your end enabled it and the fee didn’t apply correctly to the qualifying orders. Please note that our tech team always verify the installation before notifying our customers.

Also, you mentioned that you reverted your theme to the previously saved version and you had lots of issues. The thing is that our code could not be the reason for any issue if you restore the previously saved version since it wasn’t installed there before. Moreover, our installation guide has quite detailed descriptions of what code is implemented to quickly find the code that should be removed. Our team also offers free uninstallation service for all customers.

Please, contact us at email or live chat. We hope to resolve this to your benefit and earn you back as a customer.

The app works as expected. Since we had a custom theme we needed assistance getting it setup but the staff was helpful and able to install and customize it quickly for us. Thank you!
