UpCharge Fees Addons Surcharge

I have been looking for an app like this for quite some time, Very glad I came across this app. Their Support helped me install it but some app was causing it to malfunction. It took 2 days for support to get back to me about why the app is not working but Angelika Trubko helped me to resolve the problem. The app does take a bit long to load and need improvement on that aspect further than that it is an awesome app and worth the monthly fee.

After some issues in the beginning, the app now greatly improves my shop-usability, customer experience and profit margins! :-)
Especially noteworthy is the dedicated support team, which helped my install the fees and even fixed some issues in my shop along the way!
Keep it up! :-)

good support.......................................................................................:)

Great app, it does exactly what we needed. Tech support was right there to help us get it up and running right away.

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!

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.

Really great work and App. Above all that you adapt the app for your customers so that everything works.

What a great little app this is and fantastic support too.
It required a little tweak to make it do exactly what I needed - which the developer suggested and implemented very quickly.
Highly recommended!

This app is great. We provide a somewhat niche service to our customers which requires us to have a little flexibility with how we charge our customers. This app provides just that. Customer service is friendly, quick, and extremely helpful. They were also very patient with us since we have very little understanding of coding and the technical side of Shopify in general. We would definitely recommend this app to any shop owners needing extra flexibility and freedom with charging their customers.

UPDATE:
working with customer service they were able to help me with my issue super quick which is dope, so I am happy now. Careful if you get Angie as a rep though she's got a bit of sass and will talk down to you, but other than that, it's good. ORIGINAL:
Be careful, this app could stop your add to cart button from working. Support cannot even figure out why, so I'm literally sitting here losing sales.
