is there a way to login to the Sage Cloud directly from the SPP (in Intacct we call it sliding-in" ) or to we need to create a "Partner User" to access SAGE? Will this be accounted for as a regular named user? it is a free license?
You would need to create a new user specifically for you, the partner, to access a customer's site. When you access the site, you will use a concurrent user ProvideX license. In terms of Windows licensing, I would assume you would need to have a CAL and probably should account for that in the pricing to the customer.
