Your bank balance is not your profit. It’s the leftover cash sitting in an account after some transactions have cleared and others haven’t — it doesn’t reflect the taxes you owe, the bills that haven’t been paid yet, the invoices customers haven’t paid you, or the depreciation, loan principal, and owner draws that make actual profit different from cash on hand. Business owners who make decisions based on bank balance routinely overspend, underprice, and skip estimated tax payments, then face surprise tax bills, cash crunches, and “but I thought we had a great year” conversations with their CPA. The fix is knowing three specific numbers — and knowing how often to look at each one.
