But it can be obtuse to newbies.
I mean, I have coding ability, so I may say Frappe / ERPNext is great. It gives me a ready to go ERP system which I can customize quickly to the User’s specification. Setup is quick. But this is probably because I understand code.
When it comes to pure Users with no coding ability, there may be some hurdles, hopefully not too high. I do not have this mindset, this is why I hesitate to answer a straight Yes or No.
One advantage that Frappe / ERPNext has over other open source ERP system is that it has a dedicated Company led by RMehta who is committed to delivering quality code, and actively updating and revising the code, and very committed to open source.
