Since 1988, Construction Information Systems, Inc. has been helping construction firms select software, convert their data, successfully implement it, train their employees and customize it.

How it began

In the mid 1980’s, Paul Unter worked as an assistant controller for a General Construction Company in Queens NY, while attending Queens college for an accounting degree. While working for that construction company, Paul chose the company’s first software package: The Construction Manager, a DOS based integrated job cost accounting solution from Software Shop Systems. It was the beginning of the personal desktop computer market. Businesses were just adopting software to be used in this new desktop PC market. Paul worked closely with Software Shop’s implementation team. He took a manual one write system and, using this new technology successfully, duplicated it on Software Shop’s Construction Manager. Apex Computer Systems out of Long Island City, The Software Shop reseller, approached Paul to implement and train for other construction firms going through this same transition. Paul began working full time doing implementations and training for them. He was also trained on installing servers and Novell networks. In the late 80’s and early 90’s, most companies purchased the hardware together with the software, so having combined software and technology knowledge was critical and a real asset to the companies he worked with.

During this time, Paul met Theresa Corso, assistant controller at a Brooklyn based construction company and also a Software Shop user. In 1987, Software Shop Systems offered Paul & Theresa an opportunity to setup their own software sales and implementation company.

In 1988, Construction Information Systems, Inc. was born and they relocated to the Upstate Capital Region area of New York. The two co-owners had unmatched experience. By this time, Paul had successfully implemented many systems in construction firms of all specialties and sizes in the Metropolitan NY area. Contractors were seeking him out to help them automate and streamline their business processes using desktop computers.

Today 35 years later, Construction Information Systems, Inc. has successfully helped over 650 Construction companies choose and implement software. Their client list includes some of  the areas largest and most notable contractors. Today, with their team of software and hardware experts they continue to bring to their customers the latest and best tools to successfully build their business better.

Our mission remains the same - elevating efficiency and helping to drive your construction company toward unparalleled success. Let our experience and knowledge work for you! Partner with CIS.
