Born in Chokhatauri, Paichadze's family moved to Poti when he was 7 years old. He started playing career in some local youth football clubs there. During these times, football was just making its first steps in Georgia and there was only a few clubs established. However, every city had its own selection of footballers. Paichadze joined the team of Poti at the age of 16. Paichadze was invited to Dinamo Tbilisi in 1936 by coach Jules Limbeck. He made debut in Soviet Top League during that season, being able to score 13 goals in 12 games. Paichadze later declared that it was Limbeck, who pioneered the coaching in Caucasus via his lectures, attended by various managers across the region. Paichadze became top scorer of Soviet Top League in 1937 season. However, the most efficient season for him was 1939, when he scored total 25 goals for Dinamo. Paichadze was prized by the various sporting media sources, after his performance against CDKA Moscow in November, when Dinamo was able to win the game 5–4, after losing the first half 1–4. During 1941 Soviet Top League season, Dinamo was one of the leaders of league table, when the championship cancelled due to World War II. Alongside with his teammates, Paichadze joined the army. After three years of cancellation, championship again resumed in 1945. Paichadze returned to Dinamo and again became one of the key figures of the club. However, in 1947, in a game against Torpedo Moscow, Paichadze got serious injury after the collision with Nikolai Petrovich Morozov. It prevented him playing for nearly two years. After recovering, he never regained the old playing form and soon decided to retire from football. In 1953, soon after retiring from football, Paichadze was invited back to Dinamo to become a head coach of the club. He accepted and managed his former club for only two seasons without any success. He resigned in 1954, claiming that "being a good player doesn't mean you are a good coach".
