Financials have to be verifiable to be audited. Many companies have that issue, it's got nothing to do with how screwed up they were, just that they did not keep detailed enough records. No quality accounting firm is going to sign off on financials unless they are confident they are 100% accurate. In most start up companies, that bar is never met because it is not cost effective, they're using their resources to launch whatever product they're trying to sell.
