Profit is revenue you've earned. Cash is money that has actually arrived in your bank. They're two different measurements taken at two different moments, and that's exactly where a lot of good businesses run into real trouble. A business can be genuinely profitable and genuinely unable to pay its bills at the same time.
One thing to know before the rest makes sense: this gap shows up most clearly if your books are on the accrual basis, where revenue is recorded when you invoice. Many smaller businesses are on the cash basis, where revenue is only recorded when the money actually lands. If you're on cash basis, your P&L and your bank move closer together, but the same forces below, loan principal, owner draws, inventory, still open a gap. If you're not sure which basis you're on, that's worth asking your bookkeeper.
Why is my business profitable but has no cash?
I was going through a client's numbers recently and saw this exact thing: a strong profit on the page, and an owner who couldn't understand why the bank account didn't reflect it. If your P&L says you made $12,000 last month and your bank account grew by $2,000, the missing $10,000 didn't vanish. It's hiding in a few predictable places.
Unpaid invoices. On accrual books, the moment you invoice a client, your P&L records the revenue. Your bank account records nothing until they pay, which might be 30, 45, or 60 days later. For most service businesses I work with, this is the biggest source of the gap.
Inventory or materials you've bought but haven't sold or billed yet. You spent the cash. The P&L spreads that cost over time as the work gets delivered.
Debt payments. Only the interest on a loan shows up as an expense on your P&L. The principal you pay back every month leaves your bank account without ever touching your profit. A business with a big loan payment can show a healthy profit and bleed cash at the same time.
Sales tax you're holding. Money you collect as sales tax sits in your checking account but was never yours. It's owed to the state, and it can make your balance look healthier than it is.
Money you took out. Owner draws and distributions don't appear on the P&L as an expense, but they absolutely leave the account.
Why this is the gap that closes businesses
A business doesn't shut down the month it becomes unprofitable. It shuts down the month it can't make payroll. Those are different months, sometimes years apart. Growth actually makes this worse for a while, because more sales means more cash tied up in unpaid invoices and upfront costs. Plenty of businesses have grown their way into a cash crisis while their P&L looked better every month.
How to find your gap in fifteen minutes
Put last month's P&L next to last month's bank statements. Note your profit, then note how much your cash actually changed. The difference is your gap. Now account for it: how much is sitting in unpaid invoices, how much went to loan principal, how much did you take out, how much is sales tax you're holding, what did you buy that hasn't been billed through yet. When each dollar has a name, the gap stops being scary and starts being a to-do list, and the first item on it is almost always the same one: follow up on what you're owed.
