The Startup’s Guide to Managing Cash Flow

More startups fail from cash flow problems than from product problems. You can have great product-market fit, strong revenue growth, and a genuine competitive advantage — and still run out of cash if you’re not managing your cash flow carefully.

Cash flow is not the same as profitability. A business can be profitable on paper and still run out of cash — if customers are slow to pay, if the business is investing heavily in inventory, or if growth is consuming cash faster than revenue is generating it.

Know your runway. Runway is how many months of cash you have left before you run out of money, at your current burn rate. Every founder should know this number and update it regularly. When it starts dropping below six months, it’s time to take action — either raising capital, reducing burn, or both.

Build a cash flow forecast. A cash flow forecast projects your cash inflows and outflows over the next three to twelve months. It tells you not just whether you’ll have enough cash, but when potential shortfalls might occur — giving you time to act before they become crises.

Manage your accounts receivable aggressively. Invoice promptly. Follow up on overdue invoices. Consider offering early payment discounts. The cash sitting in your accounts receivable is cash your business could be using.

Manage your payment terms. Where possible, collect payment before you deliver. Annual subscriptions paid upfront are dramatically better for cash flow than monthly subscriptions. Negotiate extended payment terms with your own suppliers.

Keep fixed costs low. Fixed costs — salaries, rent, software subscriptions — consume cash regardless of revenue. Keep them lean. Every fixed cost you add is a risk you’re taking on against uncertain future revenue.

Build a cash reserve. The unexpected always happens. A healthy cash reserve — typically three to six months of operating costs — gives you the stability to handle surprises without panicking.
