SQL database was a large amount of tables alike and if you try to add a feature that it doesn't implement yet (such as drop shipping capabilities) I couldn't figure it out because its not as simple as creating a new set of forms like in Django you basically have to understand the whole system and I think the task would take a year.

It would have been better to integrate an existing system instead.

Hi, Vanderson. I'm doing the same thing here where I work. I would be interested in sharing experiences. You can contact me via my profile if you'd like to chat more about it. I would say from my part it's been a good choice, but so much complexity to deal with.
