@WayneSchulz I have to second your concern.
On the pro side, we have worked with Insperity (Previously known as Galaxy) for years and move a lot of their time and attendance product (called TimeStar) in our Abra practice. (Typically 6 to 8 systems per year). They have always been good to work with.
Two points on the con side; 1) it will be a new product for Insperity to pick up and support, especially with a Sage 100 interface, and 2) our experience with Timesheet in the past has not been a positive one. I don't have any personal experience but I offered it up as an option in an internal meeting for an Abra / MAS 500 opportunity once. The faces of our HRMS team members went ashen! A couple of them had worked with it in the past and they didn't want any part of another go-around.
