Daycos was born out of John Day’s expertise in tariffs and billing. In 1978, John & Connie Day started John Day & Associates in the basement of their home in Washington D.C. Soon after, John was asked to review a sampling of a customer’s military shipment files for accuracy. Finding discrepancies, the experience reinforced his credibility and industry knowledge, leading him to believe that other companies may be missing revenue opportunities as well. Offering post-audit services, John worked with his wife Connie, and their children, Brandon and Nanette, to establish the brand and service of the company.
