End-of-Day Reporting and Sales Analysis

What the End-of-Day Close Accomplishes

At the end of every shift or business day, a restaurant manager runs a structured closing sequence on the point-of-sale (POS) system. This process reconciles every dollar that entered and left the operation during that period. A clean close protects the restaurant from cash loss, surfaces pricing or discount errors before they compound, and produces the data you need to manage food cost and labor cost. Health departments, auditors, and ownership all rely on the integrity of these records.

The Z-Report

The most important output of the end-of-day close is the Z-report. When you run a Z-report the POS finalizes the current trading period, prints a full summary of all transactions, and resets the counters to zero so the next shift starts fresh. You cannot "undo" a Z-report, which is why you run it only at the designated close time and never before the final guest check is settled.

A standard Z-report shows:

• Gross sales – total revenue before any deductions
• Voids – transactions canceled before settlement
• Comps – meals provided free of charge (employee meals, guest-recovery)
• Discounts – coupons, promotions, happy-hour reductions
• Net sales – gross sales minus voids, comps, and discounts
• Payment-method breakdown – cash, credit/debit card, gift card totals
• Cover count – number of guests served

Cash Drawer Reconciliation

After running the Z-report, count the cash drawer carefully:

1. Remove and set aside the starting bank (the float placed at the beginning of the shift).

2. Count the remaining cash using a systematic bill-by-denomination method to reduce counting errors.

3. Record the counted amount on your reconciliation sheet.

4. Compare your physical count to the cash total shown on the Z-report.

5. Calculate the overage or shortage: Physical Count − Z-Report Cash Total = Variance.

A variance of zero is the goal. Most operations set an acceptable tolerance (often a few dollars). Variances outside that tolerance must be documented and investigated before the manager signs off. Never assume a shortage is acceptable without following your property's cash-handling policy.

Safety note: Handle cash in a secure area away from public sight. When transporting the deposit, follow your property's escort and drop-safe procedures. Lone-worker and robbery-prevention policies apply during this task.

Credit Card Batch Settlement

After counting cash, settle the credit card batch. The POS groups all card transactions into a batch that must be transmitted to the card processor. Log into the appropriate terminal or software module, verify the batch total matches the card total on your Z-report, and submit. Print or save the batch confirmation. A mismatch between the POS card total and the batch total must be resolved with the processor before you close—do not leave it for the next shift.

Calculating Food Cost Percentage

Food cost percentage tells you what fraction of food revenue was spent purchasing the food that generated it.

Formula:

> Food Cost % = (Cost of Food Sold ÷ Net Food Sales) × 100

Cost of food sold is typically obtained from your inventory and purchasing records for the period. Net food sales come from the daily sales report. A well-run full-service restaurant commonly targets a food cost percentage in the low-to-mid thirties, though the right benchmark depends on the concept and menu mix. Your operation's target is set by ownership or the general manager—your job is to measure against that target and flag deviations.

Calculating Labor Cost Percentage

Labor cost percentage measures what fraction of revenue pays wages, salaries, and related labor expenses.

Formula:

> Labor Cost % = (Total Labor Cost ÷ Net Sales) × 100

Total labor cost includes hourly wages, salaried manager allocations, and payroll taxes and benefits if your property includes them. The daily labor cost figure often comes from your scheduling software or a payroll summary printed alongside your sales report. High labor cost on a slow day is normal; the manager's job is to adjust staffing decisions to keep the ratio in line over time.

Reading Two Weeks of Data for Trends

A single day's report is a snapshot. Two weeks of daily reports reveal patterns: which days of the week drive volume, which shifts run high labor cost, and where voids or comps spike. When writing a management note based on this data:

• State the observation ("Tuesday and Wednesday posted the lowest net sales of the two-week period.").
• Offer a plausible cause grounded in restaurant operations (slow mid-week traffic, limited bar promotion).
• Recommend one concrete operational adjustment (adjust staffing levels, introduce a weekday promotion, shift prep labor to higher-volume days).

Keep notes factual, brief, and actionable. Ownership and the general manager read these notes to make scheduling and marketing decisions.

Documentation and Accuracy Standards

Every figure you record on a reconciliation sheet or calculation worksheet becomes part of the operation's financial record. Write legibly, show your arithmetic, and initial your work. If you discover an error after closing, document the correction with a note explaining what changed and why—never erase or white-out an original entry. This discipline supports the internal controls that protect both the business and you as the manager on duty.
