I'm guessing this guy isn't an accountant anymore because he was really bad at it. What he refers to as "keeping accountants happy" is actually keeping the government, investors, and partners happy. It's also answering questions like "Where is all my money going?" and "Is one of my employees stealing from me?".

Anal-retentive bookkeeping exists because life is often deeply unkind to those who fail to keep track of their money.
