Yes, As QloApps is an open-source system. So you can definitely edit the code yourself as per your requirements but only for your personal use.
However, as per our company policy, we do not allow the Reselling, whitelabeling, or any kind of rebranding of QloApps.
Also, just to inform you that if you make custom changes to the code, any issues that arise on your system by custom changes, will not be covered under QloApps' free support.
