I am working with a company that I just came into and trying to fix their books. They havent really been keepingup on their bookeeping. they have not reconsiled their account since May of 2009. They also have no record of the deposits that have come in over this time so their accountin quickbooks is showing -170,000.00. I am not sure how to fix this problem since we are talking years of discrepencies... Any advice would be appreciated..
