About Cert-In: Our Background and Expertise

Cert-In Software Systems, Inc. was incorporated in Florida in 1996 as a software development company with the primary objective of providing easy-to-use tools for contractors. In January 1997, Cert-In acquired the rights to maintain, modify, upgrade, and distribute the TRF family of products.

Over the following decades, Cert-In developed Windows-based versions of its Estimating and Time & Material programs, leveraging modern development and data-management technologies. In recent years, the software underwent a comprehensive modernization to ensure compatibility with current and future versions of Windows.

In 2025, Cert-In Software was acquired by Conest, the leading provider of estimating software for the electrical industry. This acquisition ensures the continued availability, support, and long-term evolution of Cert-In products while expanding customer access to a broader ecosystem of proven electrical estimating solutions.

"Fastest Electrical Estimating Software Out there. Cert-In's support is fantastic!! never have to wait and always get my problem solved quickly and on the first call. Ease of use and the speed of the take-off. Thousands of ready built assemblies all ready to go. The integration between you eTakeoff is the really neat part of this system. The special assemblies are so fast and easy to build, you can customize any estimate easily and fast. The ability to break out portions of the bid is very flexible and almost unlimited in how you want the breakout done. Also very fast in making the breakouts. There are very good videos of how to do different things and are easy to follow."
