At the moment there are really some bugs.

We cannot switch off the payment. See my description. That is really bad for some use cases

Every service creates a product. Imagine you create a product that is a "Basic Course" That is split in four sessions. The customer pays once and now can choose when the session will be. That means a new product? That is really disturbing

How to create the slots for sessions as above: right now I have to assign the service to one staff, who then needs to be available at the required slot. And I can do so only on the "Staff" menu. Can you imagine how complicated that is? An option where I choose the slot, then assign a staff member, would be a great improvement.
