Try to make sense of this mail from Odoo
So the new system is not the most efficient, but indeed in a nutshell the way it works is that the basic version of Odoo.sh, you can still provide on 100% commission but, the customers need to pay for the service in advance and than you invoice them the full amount of the commission.
Anything else that it's not basic Odoo.sh, the customer needs to cover the costs, not being possible to do on 100% commission, but we need to evaluate that for the customer size, amount of workers needed, and so on.
