Frequently Asked Questions
What is the difference between profit (net income) and cash flow? ▾
Net income measures revenue minus expenses on paper (accounting basis). Cash flow measures physical money entering and leaving your bank account. A business can be profitable on paper but run out of physical cash if clients pay on 60-day terms.
How do I calculate small business cash runway? ▾
Cash Runway (Months) = Current Liquid Cash / Net Monthly Cash Burn Rate. Net Burn Rate equals monthly operating cash outflows minus operating cash inflows.
What qualifies as an operating vs. investing vs. financing activity? ▾
Operating activities stem from core business revenue and recurring expenses. Investing activities involve buying/selling long-term equipment or investments. Financing activities involve bank loans, founder capital, or investor funding.
Why can a profitable business still run out of cash? ▾
Profitable companies frequently crash due to cash timing mismatches—such as paying suppliers upfront for inventory while waiting 60–90 days for clients to pay outstanding invoices.
