If you’ve ever stared at a profit-and-loss statement showing a healthy net income while your checking account tells a completely different story, you’re not imagining things. And you’re not bad at running a restaurant.
Short answer: your P&L is an accrual snapshot of profit over a period. Your bank account reflects cash movement in real time; inventory purchases, loan payments, owner draws, and sales tax collected but not yet remitted all hit your bank before (or without ever) hitting your P&L as an expense in the same way. A restaurant can post a genuine profit and still run out of cash in the same month.
Most restaurant operators watch prime cost (COGS + labor) as their main health metric, and for good reason – the National Restaurant Association benchmarks a healthy prime cost at roughly 60-65% of sales for full-service restaurants. But prime cost is a P&L concept. It says nothing about when cash actually left the building for debt service, equipment loans, or a remodel – none of which show up in COGS at all.
| Cash Drain | Why it’s invisible on the P&L |
| Loan and equipment payments | Principal portion isn’t an expense – it reduces a liability, so it never touches your income statement |
| Inventory buildup | Cash out the door the moment you buy it; expense recognized only when sold |
| Sales tax collected | Sits in your bank account as cash, but it was never yours – it’s a liability waiting to be remitted |
| Owner draws | Not a business expense at all, so profit looks untouched even after the owner has taken cash out |
Yes – this is one of the most common ways restaurants fail. Running out of cash while the P&L shows a profit is a timing problem, not a profitability problem, but it can close the doors just as fast.
The National Restaurant Association benchmarks full-service prime cost (COGS plus labor) at roughly 60-65% of sales, though the right number varies by concept and service style.
Monthly at minimum – weekly during high-volatility periods like a new menu launch, a slow season, or a big equipment purchase.
