While accounting has to be 100% accurate before filing to the IRS or shareholders, accounting can be a spectrum of accuracy at any given point over the year. But on a day to day, week to week basis, the choice should not be as binary - some founders might be ok with 80% accurate, or 95% accurate depending on the situation and risk of any given business decision.
Accounting has a set of rules which must be followed, and a set of guidance that provides flexibility to the user what they consider accurate. Ultimately it is up to the company to decide how to represent their financials, and the level of “accuracy” they need at any given time.
