Souters Sports has moved to HSBC from Royal Bank of Scotland after growing sales last year by 27% to £7 million.
Stewart Aird, founder and managing director of Souters Sports, said the company's success in the market to support commercial organisations like soccer clubs has helped compensate for cuts in spending on facilities by local authorities.
The company has worked on the pitches used by Rangers and Celtic on match days and in training. Mr Aird said Souters Sports was not owed money by Rangers when the firm went into administration.
However, another company he is involved with, Souters Irrigation Services, was owed around £500.
Souters Sports' client base also includes big names from English soccer, including Liverpool and Chelsea.
Regarding the move to HSBC, Mr Aird said: "We place a huge importance on having a strong relationship with our banking partner and took the decision to move to HSBC as they demonstrated a solid understanding of our business.
"This understanding has resulted in them offering the flexibility we require to continue to trade effectively."
He complained of a "general lack of support from our previous providers".
Mr Aird added: "We had quite a lot of debate with them over funding and lending."
A spokesman for Royal Bank of Scotland said: "We don't have authorisation from our client to comment on this case so are unable to do so."
He added: "We are fully focused on helping small businesses succeed. We also lend more to small businesses than any other bank in the UK."
