SAC was started in 1978 by former IBM engineers.

SAC was started by a group of 7 IBM executives, system engineers, and programmers. Originally an IBM Authorized Value Added Reseller (VAR), the Company sold and supported IBM S/36, S/38mid-range computer systems, with customer programming and support.

Their mission was to create an overall comprehensive system that would be used by companies selling equipment and requiring after sales service and maintenance.

Our Success.

SAC Inc., the leading developer and supplier of productivity-enhancing software for Interconnect companies, combines over twenty years of experience in Interconnect and Information Technology to create software products ideally suited to today’s Interconnect businesses.

In 1981, the firm concentrated on the software support to its client base in several countries around the world (Germany, Mexico, Argentina, and Italy).

Following this, in 1986 SAM (Service & Accounting Manager) software was successfully introduced to the North American Large Size Interconnect Business (Alaska Telephone Utilities, AT&T Montreal, TSS Detroit, Accurate California, MIS Miami , Midcom Toronto, and Brant Communication Hamilton).

As an indication of the scope and magnitude, the complete system now contains 3000 programs, and approximately 10,000,000 lines of source coding. All of which took about 35 man-years to write, test and debug. To the best of our knowledge, there is no other commercial system in operation in North America that is as simple to operate yet provides management with such awesome control over their business operations.

IDM (Interconnect Dispatching Manager).

In 2007, IDM Software was launched to small & mid-size telephone sales and service companies.
