Can you guys submit the form at https://hostbillapp.com/feature-request/ requesting an enhance integration. multiple requests should make them create such a module.
We have had correspondence with Hostbill and they tell us they are building a module. Obviously we don't have any influence on their development cycle but I would hope for something in the very near future.
EDIT - Live at:
@Adam Hostbill integration is done 🙂 1 step closer to start using enhance.
