I was hired by Software Unlimited in January, 2001 after 31 years in retail.  I have witnessed the many changes to the School Accounting System, as I’m frequently an early “beta customer” for our Development team.  I was one of the first to test the upgrades through two versions of the system as well as our cloud offering.  I always look forward to our new software updates that makes my job more efficient and reporting better.
