We sign an agreement for AWS resell services, do billing transfer. Each month we invoice for AWS spend based on previous month spend. In EUR currency.
CWISE is executing AWS resell thru AWS billing transfer. We send to your billing account invitation. You accept in your AWS account invitation and thats all.
No, there is no minimal commitment.
Easy to implement (<1H) CWISE is not needed access to your AWS accounts and no technical changes needed needed to execute
