Proper cash flow management prevents 80% of restaurant closures within the first two years. Revenue shows what you've sold, but cash flow reveals what actually hits your bank account. High sales don't guarantee you'll have money to pay tomorrow's bills.
The difference between revenue and cash flow
Revenue's straightforward: total sales for any given period. Cash flow's trickier—it tracks actual money moving in and out of your account, precisely when those transactions occur.
💡 Example:
Restaurant De Kroeg has in March:
- Revenue: €45.000
- Purchase costs: €13.500 (30% food cost)
- Personnel costs: €18.000
- Fixed costs: €8.000
Profit on paper: €5.500
But reality's messier:
- Supplier payments happen next month
- Credit card payments arrive 3-5 business days later
- Corporate accounts settle in 30-45 days
- Rent and utilities get debited immediately
You've got profit on paper, but maybe not enough cash for Friday's payroll.
Why cash flow trumps revenue
Cash pays bills. Revenue doesn't. From years of working in professional kitchens, I've seen profitable restaurants close because they couldn't cover immediate expenses.
⚠️ Watch out:
December and January create perfect cash flow storms. December brings massive revenue from holiday parties, but payments often arrive in January. Meanwhile, January's naturally slow while December's bills come due.
Monitoring your cash position
Track your liquidity weekly. That means knowing exactly how much cash you have right now versus what you'll need over the next four weeks.
💡 Simple cash flow check:
- Current account balance: €12.000
- Outstanding invoices (arriving within 14 days): €8.000
- Upcoming bills (next 14 days): €15.000
- Next payroll: €6.000
Two-week shortfall: €1.000
Now you can act. Tighten collection policies, negotiate supplier terms, or reduce inventory purchases temporarily.
Cash flow pitfalls
- Excessive credit sales: Corporate clients often pay slowly
- No cash buffer: Maintain at least one month's fixed expenses in reserve
- Seasonal blindness: Summer profits must cover winter losses
- Poor timing on purchases: Don't buy equipment right before slow periods
Tools like KitchenNmbrs help control food costs, but cash flow requires dedicated accounting systems or spreadsheet tracking.
How do you monitor your cash flow? (step by step)
Make a liquidity forecast
List all income and expenses for the next 4 weeks. Not what you expect, but what definitely comes in and goes out. Calculate conservatively.
Check your accounts receivable weekly
Who still owes you money and when? Send reminders after 14 days. Businesses are often slow payers, so keep a close eye on this.
Build a buffer of 1-2 months of fixed costs
Rent, insurance, minimum personnel costs - add up what you absolutely have to pay per month. Make sure you always have this in your account.
✨ Pro tip
Every Tuesday at 9 AM, calculate your 14-day cash runway: current balance plus expected receipts minus known expenses. If it's under €5,000, immediately contact slow-paying accounts and defer non-critical purchases.
Calculate this yourself?
In the KitchenNmbrs app you can do this in just a few clicks. 7 days free, no credit card.

Frequently asked questions
What constitutes healthy restaurant cash flow?
Keep 1-2 months of fixed costs in your account as a buffer. Limit credit sales to 30% of total revenue maximum. The remaining 70% should come from immediate payments—cards, cash, or same-day processing.
How can I prevent cash shortages during slow seasons?
Build reserves during peak months by saving 10-15% of busy-season profits. Adjust inventory purchasing for slower periods, buying less perishable stock. Create a seasonal cash flow calendar to anticipate tight periods.
What if suppliers demand immediate payment while customers pay on credit?
Negotiate 30-day payment terms with suppliers—this is standard practice. Restrict credit sales to established, reliable customers only. For large events, require 50% deposits upfront.
Does higher revenue guarantee better cash flow?
Absolutely not. December corporate events generating €20,000 in revenue but paid in February create January cash crunches despite strong sales figures.
How frequently should I monitor cash flow?
Check your bank balance and weekly obligations every Monday morning. Create monthly 90-day cash flow forecasts, especially before and after seasonal peaks.
What's the biggest cash flow mistake new restaurant owners make?
Assuming profit equals available cash. Many owners see monthly P&L statements showing profit but don't account for payment delays, seasonal fluctuations, or timing mismatches between income and expenses.
