Keystone Overview

Keystone is an independent certified public accounting firm that specializes in:


Small Business Certifcations

Keystone Advisors is an SBA-Certified HUBZone and an Economically Disadvantaged Woman-owned Small Business (EDWOSB), with a Top Secret FCL and more than 16 years of partnering with government agencies to fulfill SBA small business contracting goals while maintaining unwavering standards of quality and efficiency.

SBA Certified and HUBZone Certfied
Women-Owned Small Business EDWOSB Certified

The HUBZone program fuels small business growth in historically underutilized business zones with a goal of awarding at least 3% of federal contract dollars to HUBZone-certified companies each year.

To help provide a level playing field for women business owners, the government limits competition for certain contracts to businesses that participate in the
Women-Owned Small Business (WOSB) Federal Contract program. Some contracts are restricted further to economically disadvantaged women-owned
small businesses (EDWOSBs).
