Their support is helpful and able to solve an issue.
Great!

Their support is pretty good and was able to resolve my issue in one contact. Pretty awesome! Keep up the great work guys!

For being a simple tracking number uploader to Shopify stores this works great. We get are order spreadsheet from are supplier everyday and run it through Uptracker and the tracking numbers are store in the orders within minutes. Sure beats coping and pasting those tracking numbers to your customers.

This app is a must-have if you do volume!

They handled the problem for me instead of giving me instructions on how to do it. Thanks and much appreciated.

Had some issues but their support is very reliable and prompt!

Great App, support is very responsive and easy to work with.

This app is exactly what I was looking for. It saves me a hell lot of time when sending hundreds of tracking codes to customers which I had to do manually before. It is not that easy to setup though and there is no installation help but support assisted me greatly and even changed the app to make it easier for me.
