**This is also a feature request, but I posted it here to hopefully get a larger audience. I noticed it was already discussed in the forum regarding a shopfront. I am aware that the API can be used to achieve this. Is there any other opensource alternative (not a freemium model) that would be able to do this? I have looked at HopeBilling, not sure if it had that feature. But the project seems to be abandoned. Any idea if this feature will be implemented in ISPConfig?
