Cash Drawer Reconciliation in 2026: How Do You Balance the Till and Catch Shrinkage?

Cash drawer reconciliation is the process of counting the cash in a register at the end of a shift and comparing it to what the POS says should be there, then investigating any difference. It is the simplest internal control a restaurant has, and the one most often skipped.

Skipping it is expensive: cash shrinkage from error and theft commonly runs 1–3% of cash sales when no one is counting, and small, repeated discrepancies are how slow leaks go unnoticed for months.

What does the reconciliation actually involve?

Three numbers and one subtraction:

• Opening balance (the float): the fixed starting cash, often $150–$300, counted in before the shift.
• Expected cash: opening float + cash sales − cash refunds − cash paid out (e.g. a supplier paid from the drawer), as reported by the POS.
• Actual cash: what you physically count at close.

The difference is over/short: Actual − Expected. A negative number means short (missing money); positive means over (too much).

A worked example

Float $200. The POS reports $640 in cash sales and $40 in cash refunds for the shift. Expected drawer = $200 + $640 − $40 = $800. You count $792. You are $8 short. That is 1% of the $800 — small, but log it. If the same register is short $5–$15 every Tuesday on the same employee's shift, the pattern, not the single number, is what matters.

How big a discrepancy should trigger an investigation?

Set a threshold and stick to it. A common rule:

• Under $5 (or under ~1% of cash sales): log it, no action. Miscounts and change-making errors are normal.
• $5–$20: note it, flag if it repeats with the same person, shift, or register.
• Over $20 or a repeating pattern: investigate — recount, check the POS for voids and no-sales, and review who had drawer access.

The goal is not zero variance (that is unrealistic with cash); it is catching the pattern early.

How does a POS make this easy?

A modern POS turns a 20-minute manual exercise into a few taps:

• Records the opening float and every cash sale, refund, and pay-out automatically
• Calculates expected cash so no one does arithmetic under pressure
• Logs the counted amount and the over/short, by employee and session
• Builds a history you can scan for recurring shorts on one person or register

Direct Dine includes cash drawer sessions with opening and closing balance reconciliation built in, so the over/short and the audit trail are captured every shift — and because it is commission-free, every dollar of that cash sale is yours, not a marketplace's.

When tight reconciliation is overkill

• A cashless, card-only venue has no drawer to reconcile — the card processor's settlement report is your control instead.
• For a single-operator stall where the owner is the only person touching cash, a daily count is enough; per-shift sessions add little.
• Do not over-invest in chasing sub-dollar variances; the time costs more than the money. Set a sane threshold and move on.

Reconcile every shift, count blind (count first, then compare to expected), rotate who counts, and let the POS keep the record. That routine alone deters most casual cash loss.
