For smaller companies that need more than a small company accounting system

VIRTUOSO™ is a tool that provides managers with the information required to make informed decisions. If you can’t measure it, you can’t manage it drove the development of VIRTUOSO™.

VIRTUOSO™ was created to meet the needs of smaller companies that need more than a small company accounting system. VIRTUOSO™ is built on the company’s field-proven Comptroller System, and is a cloud based implementation of that legacy system. In use for over twenty five years, Comptroller was originally developed to support the accounting and compliance needs of small government contractors. It specifically addressed the time-consuming and labor intensive accounting and related administrative tasks associated with the management of cost based government contract work. Over the years Comptroller’s capabilities were expanded in order to satisfy needs in varied industries including small manufacturers, commercial business service providers, and non-construction contractors. In these companies Comptroller was tasked with assisting management with controlling costs and improving bottom lines, therefore becoming a true management information system.
