Restaurant Accounting: Managing Food Costs and Cash Flow

Restaurant accounting requires specialized knowledge. With thin margins and high failure rates, getting your numbers right isn't optional—it's survival.

The Restaurant Accounting Challenge

Restaurants face unique financial challenges:

  • High volume, low margin: Every penny counts
  • Inventory spoilage: Food goes bad
  • Cash handling: Tips, registers, theft risk
  • Labor intensity: Scheduling impacts costs
  • Seasonality: Demand fluctuates

Key Restaurant Metrics

Prime Cost

Prime Cost = Food Cost + Beverage Cost + Labor Cost

Target: 55-60% of revenue

This is THE most important number. If prime cost exceeds 65%, profitability is nearly impossible.

Food Cost Percentage

Food Cost % = Cost of Food Sold ÷ Food Sales × 100

Industry target: 28-35%

Beverage Cost Percentage

Beverage Cost % = Cost of Beverages ÷ Beverage Sales × 100

Target for liquor: 18-24% Target for beer: 20-28% Target for wine: 35-45%

Labor Cost Percentage

Labor Cost % = Total Labor ÷ Total Revenue × 100

Target: 25-35% (varies by concept)

Inventory Management

Weekly Inventory Counts

Count inventory at the same time each week:

  • Walk-in cooler
  • Freezer
  • Dry storage
  • Bar

Calculate Cost of Goods Sold

COGS = Beginning Inventory + Purchases - Ending Inventory

Track Waste

Record all:

  • Spoiled items
  • Overcooked/mistakes
  • Comp'd meals
  • Employee meals

Cash Flow Management

Daily Cash Handling

  1. Count drawers at shift start
  2. Run Z reports at close
  3. Separate tips, deposits, and change
  4. Reconcile to POS system
  5. Bank deposits next business day

Weekly Cash Flow

  • Monday: Pay vendors
  • Tuesday: Review last week's numbers
  • Wednesday: Mid-week performance check
  • Friday: Prepare for weekend
  • Saturday/Sunday: Peak operations

Managing Seasonality

Build reserves during peak seasons:

  • Valentine's Day
  • Mother's Day
  • Summer (for some)
  • Holiday season

Plan for slow periods:

  • January
  • September (back to school)
  • Weather-dependent dips

Tips and Service Charges

Tracking Tips

  • Record all tips received
  • Calculate tip pools/distribution
  • Track credit card tips separately
  • Report tips for payroll tax

Service Charges

  • These are restaurant revenue
  • Must be reported as income
  • Taxed differently than tips

POS Integration

Connect your POS system to your accounting:

  • Automatic sales recording
  • Category breakdowns
  • Time-based analysis
  • Employee performance

Ledger Flow integrates with major POS systems to automate this entirely.

Weekly Financial Review

Every week, review:

Sales ☐ Total sales vs. last week ☐ Average check ☐ Covers (number of guests) ☐ Sales per labor hour

Costs ☐ Food cost percentage ☐ Beverage cost percentage ☐ Labor cost percentage ☐ Prime cost

Variances ☐ Identify any concerning trends ☐ Investigate outliers ☐ Adjust purchasing if needed

Common Mistakes

1. Not Taking Inventory

You can't manage food cost without counting.

2. Ignoring Variance

A 2% food cost increase might seem small—it can eliminate your profit.

3. Poor Cash Controls

Cash handling requires strict procedures.

4. Over-ordering

More inventory = more waste = higher costs.

5. Understaffing to Save Labor

Service suffers, tips drop, turnover increases.

Technology for Restaurant Accounting

Essential integrations:

  • POS System: Toast, Square, Clover
  • Inventory Management: BlueCart, MarketMan
  • Scheduling: 7shifts, HotSchedules
  • Accounting: Ledger Flow (with restaurant features)

Restaurant Accounting Checklist

Daily: ☐ Reconcile cash drawers ☐ Review sales by daypart ☐ Record any waste/comp

Weekly: ☐ Take physical inventory ☐ Calculate food cost ☐ Review labor vs. sales ☐ Pay vendors

Monthly: ☐ Reconcile all accounts ☐ Review P&L statement ☐ Compare to budget ☐ Analyze trends

Quarterly: ☐ Menu costing review ☐ Vendor negotiations ☐ Labor scheduling optimization ☐ Equipment maintenance budget

Improving Your Numbers

If food cost is too high:

  • Review portion sizes

  • Reduce waste
  • Simplify menu

If labor is too high:

  • Optimize scheduling
