Cash flow is the most important mystery you have to solve. Cash flow is the real heartbeat of business. And unfortunately, cash flow isn’t intuitive. It’s tricky.
Unfortunately, it doesn’t always work out that way. Because of accounting rules, sales are sales we made for this month, and costs are what it cost us to produce what we sold this month, and expenses are what we incurred this month. But — and here’s the brutal mystery and trickery of it — we might have paid those costs and expenses months ago; and we might not get paid for those sales until months from now.
So we can easily be profitable and broke. Not intuitive, but it happens a lot. Most product businesses need to spend on building or buying the product, plus packaging, assembly, and distribution, long before they can sell it. And most business-to-business sales involve waiting months to get paid.
If we could only get the research to prove it, we’d find that a surprising percentage of businesses that go under are profitable when they do.
Managing the cash flow, planning on cash flow ups and downs, is one of the fundamental purposes of good business planning. You lay things out in order: how long you wait to get paid, how early you have to build, debt repayments and capital purchases that don’t show up in profit and loss. And good planning helps you anticipate problems in time to deal with them. Go to a bank with a good history and a plan showing cash flow hills and valleys, weeks or months in advance, and the bank loves you. Try it on Tuesday because you’re going to miss payroll on Friday, and you’re out of luck.

Watch how much faster the cash deficit grows when your sales grow fast and you don’t have an all-cash business.
