Celebrating over 51 years providing COBOL tools, support, and services to our clients.

We are constantly searching for and evaluating the best, most cost-effective technologies. Since 2009, ESI has partnered with COBOL-IT, the developer of the fully supported open-source based COBOL compiler, COBOL-IT, and its related tools; ESI is the primary US and Canadian support arm for COBOL-IT as well as a distributor of COBOL-IT products.

We are a technology company, but we focus on helping solve business problems for our customers and the people they serve with the best technologies for them. From adding new revenue or cost saving functionality to modernizations and migrations to less expensive and more flexible environments, serving your best interests is our most consistent motivator, collectively as an organization and individually as employees. It’s what we enjoy and do quite well!
