Exact Tooling review for Upcharge Fees & Product Addons

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.
