Connecticut Government and Education Municipal Software.

GEMS has been the trusted brand for Connecticut Government and Municipal Software for over 30 years.

In 2022, Kim DeSimone, a legacy employee with the company, became the proud new owner of Gemni Software. 

Gemni’s mission is to provide Connecticut municipalities with the highest customer service to make tax season less of a headache. Gemni is rapidly growing to ensure Connecticut municipalities continue to have a choice for all their budgetary software needs.

We take great pride in our products and services and work with our customers to continually improve the systems. 

Here is what some of our clients have to say:

"Our tax system conversion into Gemni software was smooth and seamless.  The team was a quick phone call away, and any questions or concerns were addressed and clearly explained.  The service is top notch, and the software is designed to meet the needs of our municipality."

"I have worked with Gemni for many years and have NEVER considered going anywhere else for my tax and assessment administrative software needs. The software is easy to use and they are very open to making changes suggested to them at the user group meetings they hold at least twice per year. The number one reason I am a loyal customer is due to their high level of customer service. They are very responsive to our needs, and although I know they cater to a variety of businesses, when I reach out for help, I feel like my business is the only one that matters."

Director of Assessment & Revenue | Town of Southington, CT
"Unbeatable customer service with immediate responses to questions and issues. Step by step instruction with OPM reports, Grand List assistance, and all other matters related to Assessor functions. Software that's simple to understand and navigate. Management always solicits feedback and suggestions to improve product."
