Money
Pricing, costs, cash flow, bookkeeping, taxes and funding: the numbers that decide whether an idea runs, for owners who aren’t accountants.

Price and costs are where ideas usually break, and the fault shows in arithmetic. A product that sells for $40 and costs $28 to make and ship leaves $12; with $600 a month in fixed costs, that’s 50 sales before the business pays you a dollar. Self-employment tax is 15.3% on top of income tax, and for the rest the IRS and an accountant have the last word.
How to price a product sets a first price that covers every cost of a sale, and how to calculate your break-even point works that sum with a product and a service example, your own pay counted. When sales come in and nothing is left, what to check first when a business isn’t making money goes through the margin, fixed costs, what a customer costs to win, demand and your hours, in that order.
