Your P&L shows a profit. Your bank account says otherwise. This is one of the most common and most confusing situations in the restaurant business. Here's what's actually happening.
You sit down with your accountant, look at the P&L, and it shows a $4,000 profit last month. Then you look at your bank account and there's $800 in it. This is not a math error. This is cash flow, and it's one of the most disorienting things that happens to first-time restaurant owners.
Your P&L measures revenue minus expenses on an accrual basis - meaning it records transactions when they happen, not necessarily when cash moves. Your bank account measures actual dollars in and out. The gap between them is where restaurants get into trouble.
Here are the most common reasons a profitable restaurant runs out of cash:
Loan payments - the principal portion - don't show up as an expense on your income statement. Only the interest does. So if you're paying $3,000/month on an SBA loan and $2,400 of that is principal repayment, your P&L only shows $600 as an expense. But your bank account loses $3,000. This is the single most common reason operators are confused by the gap between profit and cash.
If you spent $8,000 stocking up for a busy season or a new menu launch, that inventory purchase hits your bank account immediately but only hits your P&L as COGS when the product is actually sold. In the meantime, the cash is gone and the profit looks fine on paper.
If you do catering or events, you might invoice clients and record the revenue immediately while waiting 30–60 days to actually get paid. Your P&L looks great. Your bank account does not.
Sales tax collected from guests sits in your bank account until you remit it - usually monthly or quarterly. That money was never yours, but it inflates your account balance until it leaves. Owners who spend it accidentally create a serious problem when remittance is due.
If you're taking money out of the business as an owner draw (common in LLCs and S-corps), those draws don't show on the P&L as expenses. So the P&L might show $4,000 profit while you took $5,000 out of the business - meaning you actually went backward in cash, with no visible sign of it on the income statement.
Every week, track three numbers: cash in (actual deposits), cash out (actual payments made), and ending bank balance. Compare it to your P&L weekly. When the gap widens, figure out why before it becomes a crisis.
Understanding where your cash actually goes is the difference between a restaurant that survives a slow month and one that doesn't. Profit is the goal. Cash flow is what keeps the lights on.
