Overall, I was dissatisfied with many aspects, starting from the inability to create a non-template design, and ending with various paid limitations on working with products. Nethouse is a PAID system for creating any somewhat decent website. Don't be fooled by this advertising. Every little thing will cost money, and in the end, the website will turn out to be significantly more expensive than you think.
I was also unhappy with the functionality - it's small, non-expandable, and weak. It often fails to solve basic tasks, such as calculating shipping costs, which ultimately falls on the store owner's shoulders. The templates are not "selling"; my conversion rate on their templates was more than twice as bad compared to my old site. The admin panel is not suited for managing a product range even for 100+ items. Technical support does not respond (if your question has been asked on forums, FAQs, or the internet - they will not respond to you at all). Draw your own conclusions. It may be possible to create a selling store on this platform, but it will be expensive and require a lot of experience and understanding of market specifics. Personally, with my more than 4 years of experience in e-commerce, I was unable to achieve this in almost 3 months, but thankfully I found many more effective solutions.
