At Open Systems, we are dedicated to developing business solutions that meet the needs of our customers.

Open Systems was founded in 1976 on the premise of delivering powerful accounting software solutions to small and mid-market customers. Dr. Michael Bertini, the CEO of Open Systems, purchased the company in 1990. Consistent with its original vision, Open Systems provides tools to make the customization and modification of our software as simple and straightforward as possible. This approach, unique in the industry, has served well to protect client investment in technology.

The software solutions offered by Open Systems Inc. are sold and supported through an experienced network of Open Systems value-added resellers, independent software developers, in-house consulting teams, accountants, and international distributors.

Throughout its 30+ years, Open Systems has worked with this network to deliver business software solutions to thousands of small-to-middle sized markets. This channel approach recognizes the incredible expertise that our partners can bring to their clients, truly adding value to our solutions.

OSAS is one of the most widely used business management platforms in the mid-market; thousands of companies have elected to use OSAS to run their business operations. Since 1995, Open Systems has also offered TRAVERSE, a flexible, adaptable software suite built with Microsoft technology. We also offer a series of manufacturing, distribution, construction, eBusiness, not-for-profit and customer relationship management (CRM) applications, all tightly integrated to our OSAS and TRAVERSE platforms. The result is a single source solution for all of your business needs.
