I appreciate the excellent and helpful support staff and I will give 5 stars.

ZenCart is an almost dead CMS. There are no more updates. There are expensive maintenance costs, nasty support staff and rental server companies like Mafia.
You should also migrate and come to the wonderful free CMS WooCommerce world. Free plugins, paid plugins, everything is amazingly high performance. It was a great experience for me.

This software is not recommended for beginners. However, it is very useful for those who are familiar with the database and have a DIY spirit.

The staff of this company are very kind. You can get in touch 24 hours by chat. If there is a problem, they will cooperate to solve the problem as much as possible.
In fact, there were some bugs. The software is so complicated that the situation is different from shop to shop, so there is no way. However, I found a way to avoid the bug and eventually succeeded in the transition.
I recommend buying migration insurance. Migration insurance is intended to remigrate if migration fails.

I appreciate the excellent and helpful support staff and I will give 5 stars.
Thank you to the great Ukrainians!
