Began his career as an amateur for Norwich City and Woolwich Arsenal, while a soldier in World War I.
Impressed as a forward for Arsenal Reserves in a London League game at Tottenham on 8th September 1906, but when he left the armed services, he joined Reading as a professional.
Spent 18 months at Elm Park before coming to White Hart Lane with Ernie Coquet for a total cost of £500 for the pair of players in February 1908.
Minter was a serving sergeant in the Tottenham Royal Engineers during World War I and he won the Meritorious Service medal for his work in the army.
A determined goalscorer, Billy made an immediate impact on the side with his strike-rate. In his time at Tottenham, he scored 95 goals in 243 League appearances, which was a club record which stood until 1930 and is tenth in the all-time goal-scoring charts for the club now (mid 2007).
His goals helped Tottenham to the 1910 London FA Challenge Cup and the 1920 Second Division title, before he moved into training at the end of that season. He was still a player then, as he was when he eventually took over as manager in February 1927.
Performed trainer duties for England when they played Wales in Wrexham in March 1926 and then eight days later, he played for Tottenham in place of Frank Osborne, who was ill ahead of the match and he turned out as a forward against Hull City in a friendly. His last match as a player came on 29th April 1926 for the "A" Team at our Cheshunt training ground against Waltham Comrades.
His tenure as manager ended when he gave way to Percy Smith in November 1929. This was not the end of his time at Spurs though, as he stayed on the staff at the club for another four years as a reserve team trainer, assistant manager, part-time first team trainer and club scout. Minter was assistant secretary from 1933 until his death on May 21st 1940 at his home in Bruce Grove, Tottenham.
