Now proudly owned by Conest Software. Cert-In Software Systems, Inc. was incorporated in Florida in 1996 as a software development company whose primary objective was to provide easy to use tools for contractors. In January of 1997 we acquired the rights to maintain, modify, upgrade and distribute the TRF family of products. During the last twenty years we have produced Windows versions of the Est

imating and Time & Material programs, using state of the art development and data management systems. Davenport, President of Cert-In Software Systems, Inc. managed an overseas office for a large Florida Contractor for 11 years. During that time he had full responsibility for the development of estimates, purchasing of material, and management of many projects. The projects were multi-trade projects, which included HVAC, Plumbing, Fire Sprinkler, Electrical, Fire Detection and Chemical Fire Suppression systems. Mr. Davenport’s background in the management of a contracting business gave him a clear understanding in the need to be able to accurately prepare an estimate quickly and efficiently. This understanding led him into the preparation of programs that would make it easy for estimators and project managers to accomplish their tasks. The creation of the first versions of the Cert-In Invoice Manager and the Cert-In Purchase Order programs, were based entirely on a need to provide a project manager with the tools that he could use to quickly prepare and manage schedules of values and invoices and purchase material for a project.
