I've had problems with billing, including the impossibility of going back once a payment has been made. The application otherwise works well, but I recommend paying attention to the payment options and checking the conditions carefully. It may be useful to compare with other competing solutions.

I installed the plug-in after several bad experiences with other developers. The plug-in had a pretty good designed interface, and it looked like it could cover our needs, which were very simple. Just placing orders and printing labels in 4 x 6 format, standard for the logistics industry. Their support assured me it was possible and were ready to charge us 89USD/ month. However, on trying to ACTUALLY configure the plug-in, it became a never ending string of meetings, emails, and chats with tech support. They will never say their software doesn't do something, and will string you along and try to blame other products and developers. Finally, after over a week of wasting time with them, sending emails to other developing teams, etc. I actually found out their software wasn't working for us at all. We JUST needed to generate and print labels in a standard format (4x 6) with two carriers in two countries in the world. One would think that's really basic in e-commerce, right? Think again. Everything they said was possible, turned out to be untrue. Very disappointed, they made my company waste over a week of our time. Beware of this company. They continue to string you along with incomplete information until you find things out on your own. Don't pay for this plug-in. It doesn't work.
