I ran into this same WiseCP + Enhance provisioning gap and ended up fixing a clean module for it.
Mine is not an official Enhance or WiseCP release. It talks to the Enhance API directly and handles the basic hosting lifecycle: create org/login/member/subscription, optional website creation, suspend/unsuspend, soft delete, upgrade/downgrade plan changes, and SSO through an owner/superadmin/sysadmin member.
I am selling it for $150 one-time. No recurring fee, no free updates. Install help or customization would be separate.
If anyone in this thread is stuck trying to get WiseCP + Enhance working, email kraken@promethean-dynamic.com and I can send details.
