The Big Idea
Most small business owners don’t fail because their product is bad. They fail because they never understood their numbers. Bookkeeping Made Simple argues that bookkeeping — the daily, systematic recording of every financial transaction — is not a clerical task to outsource and forget. It is the core financial intelligence system of your business. When done correctly, it produces the three statements that answer every question that matters: Am I profitable? Am I solvent? Will I have cash to operate next month? Flannery’s argument is direct: financial illiteracy is not an innocent gap. It is a slow, quiet killer of businesses that could have survived.
