Bilches began transitioning to the managerial side by becoming the player-coach for Team Argentina in the 1978 Mini World Cup soccer tournament. In the winter of 1980, he served as the head coach for Edmonton Italo-Canadians in the Edmonton District Soccer Association's indoor league. In 1990, he returned to the province of Ontario to manage America United in the National Soccer League. He was the head coach for NSL rivals Scarborough International for the 1991 season. He continued coaching in the NSL in 1993 when he was hired by Windsor Wheels in the preseason. Unfortunately, his stint in Windsor was short-lived as he was dismissed after the arrival of new ownership.
