If you want to create an administration profit center you just have to :
- create a profit center and name it as you prefer (ex : "Administration desk")
- choose the type "article management"
- add all payment methods and possibly all articles.
- add a staff tag with the role admin on this profit center in order to have access to all the functionalities.
An admin point allows you to manage disputes, top-up / refund Cashless tags as administrator, etc.
It is often on this profit center only that the offered credits are available.
