Agreed @MarkChinsky
Another thing that is bullcrap is that customers off-plan with Sage 100 cannot buy Sage CRM. It's freaking stupid.
That same customer can buy Salesforce, Sugar, MS CRM, etc. but not Sage CRM.
I have been told that if Sage allows that, it is a dis-incentive to staying on plan with ERP. Of course, that's balderdash as CRM and ERP serve different purposes and should have different upgrade / maintenance schedules.
The Sage mentality is ""we have a 90% retention rate on M&S and want to keep it that way!""
Well ... 90% retention equals 10% attrition. 10% attrition means you completely turn over / lose all your customers every seven years. (Do the math if you don't believe)
Of course, back in the day, new sales to replace drop offs were fast and furious but those days are gone. So the 90% retention is nothing to crow about as a core business strategy.
