How It All Began

Quality Data Service, Inc. is a privately owned, leading edge software development company that has been providing application software systems to municipalities since April 1981. QDS has over 30 years of experience in developing solutions exclusively for the public sector marketplace. In fact, municipal software development and implementation is all we do: all of our resources are geared towards providing our clients the latest software innovations and are always up to date with State regulations and modifications.

Developed locally, QDS has been in a privileged position in addressing all of the State of Connecticut’s municipal requirements. Our applications are used in over 200 towns, boroughs, and districts in Connecticut - a 90% market share - making us the undisputed industry leader since 1981. Our applications work for municipalities of all sizes, from a big city like Waterbury, CT (over 50 users) to a smaller tax district like East Killingly Fire District (1 user).

We are members of CAAO and CTx and have certified Assessors and Tax Collectors on staff whose knowledge is surpassed only by their courtesy. We also provide on-site training as suits our customers’ needs and offer software support, training, and customer service from our office located in Waterbury, Connecticut.

For impeccable service, and superior software development and implementation, choose QDS today!
