I've been going through a new Sage 100c implementation and can share that, unsurprisingly, _**Sage is not any better equipped to manage or service a subscription customer than they were to manage/service a customer on perpetual**_.
Unfortunately, when the EU is on subscription they largely have to make requests to Sage for any changes to their subscription. And this is where things fall apart. Sage is used to ignoring us (the VAR) and we cannot do much of anything. They don't seem to realize that customers have a higher level of expectations around customer service and response times.
In short, just a warning not to be fooled by any slick Sage marketing making it appear as if Sage actually has processes in place to service these new subscription customers. In my experience, they don't (witness the fax ordering of info).
Example, EU decides to UG from silver to gold level support. Sage asks them to fax in their payment info all over again to the Sage fax machine. And please let Sage know when you faxed it so they can run to the machine to check....
Be prepared -- the only thing that subscription appears to change related to Sage is you unexpectedly become Sage's unpaid complaint department and customer service desk.
I have found that telling the customer that they must call Sage to make a change on their account only delays the amount of time before you must step in and figure out why nobody responded to the EU.
My sense is that this level of disorganization is going to burn through Sage staff at an even faster rate than prior years. Beware and guide your customer expectations as much as possible.
