As a homebuilder that strives to deliver a high level of service to its customers, Longwood looks for the same when it comes to choosing its partners and D&A has managed to impress us with their Team’s knowledge and professionalism.

As an individual who requires a hands on approach to learning new software, D&A offered an affordable as well as efficient manner of training while upgrading to Sage AccPac. As a prior user of AccPac Plus, I was quite aware of the functions and abilities of AccPac but required training in maneuvering in Sage.
