The 180 strong firm, headquartered close to the University of Bolton Stadium on Chorley New Road, has been providing audit services since 2017 and been a supporter of the club for many years.
The company will now assist in publishing the first set of financial figures released by the club since 2017.
Speaking about the appointment, Wanderers chairman Sharon Brittan said: “Cowgills has been a valuable partner of ours for a number of years and is a big local company who cares about our community.
“In particular, I would like to make a special mention of Jason Elliott who was very helpful before we completed the takeover in providing his specialist recovery advice and he has continued to work closely with us since.
“I am delighted that Cowgills will continue to support us and be a crucial part of our onward journey.”
Cowgills audit partner Stuart Stead added: “As a business established in Bolton, Cowgills has always been passionate about working with the club.
“Although our primary focus is to deliver audit services, myself and Jason will be working closely with Sharon and the board of directors providing ongoing advice to ensure the continued success of BWFC after a challenging few years.”
