Quick answer: Profit is revenue minus expenses recorded over a period, regardless of when cash actually changes hands. Cash flow is the real-time movement of money in and out of an account. A month can be profitable on paper while cash flow is negative, if income is earned but not yet received in cash.
Can a business be profitable and still go bankrupt?
Yes — this is one of the most cited reasons small businesses fail: running out of liquid cash even while showing a profit on paper, because expenses in cash outpace collections.
Is it possible to have negative profit but positive cash flow?
Yes, for example if a large customer prepayment arrives in cash before the associated costs and revenue recognition catch up — cash flow can be temporarily positive even in an unprofitable period.
A side-by-side example
A freelancer invoices $5,000 for work completed in January. On paper, that's $5,000 of January profit. If the client doesn't actually pay until March, January's cash flow reflects $0 received, even though the 'profit' was earned in January.
Meanwhile, January's rent, utilities, and groceries still had to be paid in cash — creating a cash flow shortfall in a month that looks profitable on paper.
Why this matters even outside of business
The same mismatch shows up in household finance whenever money is 'earned' or 'owed' before it's actually received — a bonus that's promised but delayed, or reimbursement for an expense that hasn't been paid back yet.
Treating promised-but-not-yet-received money as spendable cash is one of the most common causes of an unexpected cash flow gap.
The practical rule of thumb
Only count money as available for a cash flow forecast once it has actually landed, or once its arrival date is highly certain and confirmed.
Profit projections are useful for long-term planning; cash flow forecasts should stay conservative and date-specific.
