Cash Reconciliation: How to Close a Shift Properly

Why Reconciliation Matters

Cash reconciliation — matching the physical money in the drawer against POS records — is the most important step when closing a shift. Without it, you don't know if today's cash actually matches the recorded transactions. And small problems that go undetected today become big problems at month-end.

Step 1: Stop Accepting New Transactions

Before starting reconciliation, make sure no new transactions come in. If a transaction enters mid-count, your numbers won't match.

In practice: announce to the team that this shift is closed for new transactions. If a customer still needs to pay, complete that first, then begin closing.

Step 2: Count Physical Cash by Denomination

Count per denomination — this is more accurate and faster than counting the total all at once:

• $100 bills: ... × $100 = ...
• $50 bills: ... × $50 = ...
• $20 bills: ... × $20 = ...
• $10 bills: ... × $10 = ...
• $5 bills: ... × $5 = ...
• $1 bills: ... × $1 = ...
• Coins: total = ...
• PHYSICAL TOTAL: ...

Tip: count twice. The first count often has small errors that surface in the second count.

Step 3: Compare to Expected Balance from POS

Your POS calculates expected cash in the drawer based on this formula:

Opening balance + Cash in (cash sales) - Cash out (withdrawals) = Expected cash

Compare this to the physical total from Step 2.

• Exact match: Perfect. Close the shift with confidence.
• Small discrepancy (under 0.1% of cash sales): Normal for cash-heavy businesses. Record as variance and move on.
• Significant discrepancy (over 0.5% of cash sales): Investigate before closing the shift.

Step 4: Investigate Discrepancies (If Any)

If there's a significant discrepancy, check common causes:

• Unrecorded cash withdrawals. "Oh right, I took $15 to buy ice." This is the most common cause.
• Cash transactions not entered in POS. Customer paid, but cashier forgot to record it — money is there but no record.
• Incorrect opening balance. If the opening balance entered was inaccurate, the expected balance will be wrong too.
• Miscounted change. Check today's larger transactions — maybe change was miscalculated on one of them.

Step 5: Close Shift and Save Report

After reconciliation is complete:

• Enter the physical count into the POS (as "actual cash")
• The POS will automatically calculate the discrepancy
• Add notes if anything needs explanation ("$2 short, likely change miscalculation")
• Close the shift
• Print or save the Z-Report

Step 6: Prepare for the Next Shift

Before leaving, set up the drawer for the next shift:

• Deposit excess cash somewhere safe (safe or bank)
• Leave a standard opening balance for the next shift (e.g., $150 in balanced denominations)
• Make sure the printer has enough paper

Tips for Smooth Reconciliation

• Always count the opening balance accurately. This is the foundation of the entire process. An estimated opening = a reconciliation that will never match.
• Record every cash withdrawal immediately. Don't delay — 30 seconds to record now vs 15 minutes investigating at shift end.
• Separate shifts per cashier. If there are 2+ cashiers, each needs their own shift. Shared shifts = shared accountability = no accountability.
• Make reconciliation routine, not an event. If you reconcile every closing, the process takes 10-15 minutes. If you rarely do it, it becomes painful because so much went unrecorded.

The Bottom Line

Cash reconciliation isn't optional — it's fundamental to healthy cashier operations. The process isn't complicated: count physical cash, compare to POS, investigate discrepancies, close shift. What makes the difference is consistency. Cashiers who reconcile every shift will have minimal, controlled discrepancies. Those who rarely do will keep struggling at month-end.
