BIDEFORD commercial manager Kevin Cook has questioned the Robins' financial direction in an open letter on the club's website.
Writing on the fans' forum, Cook criticised the board's decision to change his payment structure.
He said: "The board have decided after merely four and a half months and having received a large cheque from the major partnership, to end our agreement.
"They have stated they are not prepared to pay for my expenses as part of a retainer on a monthly basis.
"I believe this to be a very short-sighted decision which does not allow for a longer financial security which would preserve the club and not require it to go cap in hand every time a bill turns up."
After his appointment in the summer, Cook secured a three-year sponsorship deal with the supermarket Morrisons.
His forum posting also mentions numerous other potential sponsors, but Bideford chairman Roy Portch has questioned the validity of some of these.
In response, Portch criticised Cook for discussing financial matters on the internet.
He wrote: "Certain issues should be kept within the confines of the boardroom and not on the forum, which is visited by many people outside of Bideford Football Club.
"The directors feel it was very unprofessional to post this letter and have made the decision to have it deleted.
"It was obvious that the club could not continue to pay Mr Cook a weekly wage plus 25% commission on net income. So he was offered a very generous 30% commission on net income without a wage.
"If Mr Cook has any faith in his ability as a fundraiser he should have found this offer very acceptable."
