Over and short are symptoms rather than diagnoses. Work through the causes in order of likelihood, using the Change Counter calculator to isolate which denomination the difference actually lives in before you start asking people questions.
A variance investigated within ten minutes of closing usually resolves. The same variance investigated the next morning rarely does, because the details that would explain it have already gone.
1. Confirm The Count Itself
Before anything else, assume the count is wrong. It usually is. Recount the highest value denomination first, since a single missed note there produces most of the variances businesses see, then work down. Do the recount blind rather than looking at the previous figures.
What The Numbers Suggest
Compare the variance against your denomination values. A difference matching a note value exactly points at a miscount or wrong change. A difference of exactly ten times a value points at a typed digit. A difference that is nothing like any denomination often points at the expected figure instead.
- Recount the highest value denomination before anything else.
- Check whether the variance equals a single note value.
- Look for a subtotal that is ten times its neighbour.
- Have a second person recount blind rather than checking your work.
2. Check The Opening Float
A float that was assumed rather than counted at the start of the shift makes every closing figure unreliable. Verify what was actually counted in, by whom, and whether it was signed for. A round number variance very often traces back to a float that was short before the first customer arrived.
Float Drift
Floats drift when staff borrow change between lanes, when a previous shift left a discrepancy uncorrected, or when the standard mix was never rebuilt properly. If floats are a recurring source of variance, tighten the handover rather than treating each incident separately.
- Verify the float was counted in and signed for.
- Check whether change was borrowed between drawers.
- Rebuild floats to a fixed denomination mix, not just a value.
- Look for the same variance appearing on the following shift.
3. Look For Change Given Wrong
Handing back the wrong note is the most human cause and the hardest to prove. A shortage that matches the difference between two note values is a strong signal, particularly at busy periods when two similar notes are involved. A matching overage on another drawer sometimes confirms it.
Reducing The Risk
Counting change back to the customer aloud remains the most effective countermeasure, along with keeping high value notes visible on the counter until the transaction completes. Both are training issues rather than technology issues.
- Compare the variance with the gap between two note values.
- Check whether the shift was unusually busy at a specific time.
- Reinforce counting change back aloud during handover training.
- Keep the tendered note visible until change is given.
4. Trace Refunds And Voids
Pull the refund and void report and match every line to a physical slip. A refund recorded in the system where no cash left the drawer creates an overage. Cash handed back with no record creates a shortage. Both are common and both are quickly found once the slips are laid out.
The Card Refund Trap
Card refunds appear on many reports in the same column as cash refunds. If your expected figure deducts them, the drawer will show a shortage of exactly that amount every time. This single misunderstanding explains a large share of persistent variances. See balancing a cash register.
- Match every refund line to a physical slip.
- Separate card refunds from cash refunds before adjusting.
- Investigate refunds with no matching slip immediately.
- Check whether a void was processed after cash had already moved.
5. Find Undocumented Paid Outs
Cash taken from the drawer for a delivery, a taxi or supplies without a receipt in the drawer produces a clean shortage with no explanation. Ask directly and without accusation, because these are usually genuine expenses where the paperwork was skipped in a busy moment.
Preventing Recurrence
If paid outs happen regularly, the drawer is being used as a petty cash tin and should be replaced with a proper fund. Establish an imprest amount and vouchers instead, as described in petty cash reconciliation.
- Ask about paid outs before assuming a loss.
- Require a receipt in the drawer for every paid out.
- Cap the value a single person may pay out.
- Move recurring expenses onto a petty cash fund.
6. Rule Out Shared Drawers
If two people used the drawer, the variance belongs to neither of them and no investigation can assign it. Confirm who had access during the shift, including anyone who stepped in briefly at a peak. This is usually the point where an investigation either succeeds or becomes impossible.
The Structural Fix
Shared drawers are a design problem, not a discipline problem. Issue individual drawers with counted floats, or count and sign at every handover. Until that changes, expect a proportion of variances to remain permanently unexplained.
- Establish exactly who had drawer access and when.
- Include brief cover during breaks and peaks.
- Stop assigning variances on shared drawers to individuals.
- Fix the handover process rather than repeating the investigation.
7. Screen For Counterfeit Notes
A counterfeit note removed at the count produces a shortage equal to its face value. Check high value notes against the security features your currency uses, and handle any suspect note according to your own policy and local law rather than returning it to circulation.
Where They Enter
Counterfeits usually arrive during busy trading, at low light, or through a distraction technique at the counter. If one appears, check the transaction log around the likely time and brief the team, since the same note pattern often appears more than once in an area.
- Check the variance against a single high value note.
- Verify security features rather than relying on feel alone.
- Follow local law and your own policy for suspect notes.
- Exclude the note from the count and record it separately.
8. Document The Outcome
Whatever you find, write it down, including the checks that found nothing. A variance record that says what was ruled out is far more useful three weeks later than one that only records the amount, because it lets the next investigation start where this one stopped.
Turning Records Into Patterns
Log every variance including those inside tolerance, then review the log monthly. Patterns by shift, by lane, by day of week or by staffing level emerge quickly and point at process problems that no single incident would reveal.
- Record the amount, the direction and every check performed.
- Complete the counted by and verified by fields on the report.
- Log variances inside tolerance as well as outside it.
- Review the log monthly for patterns rather than individuals.
Worked Example
A drawer closes twenty short. The supervisor works through the causes in order rather than jumping to a conclusion, and finds the answer in under ten minutes.
| Check | Result | Next Action |
|---|---|---|
| Recount high value notes | Agrees with first count | Move on |
| Opening float | Counted and signed, correct | Move on |
| Variance versus note values | Equals one 20 note exactly | Suspect wrong change or missing note |
| Refund slips | All present and matched | Move on |
| Paid outs | One delivery, receipt present | Move on |
| Drawer access | One cashier throughout | Likely wrong change at peak |
The outcome is recorded as a probable change error at a known busy period, with the checks performed listed alongside. Nobody is disciplined for a single incident, and the log will show whether it repeats.
Final Checklist
- Recount the highest value denomination blind.
- Verify the opening float was counted and signed.
- Compare the variance against single note values.
- Match every refund line to a physical slip.
- Separate card refunds from cash refunds.
- Confirm every paid out has a receipt.
- Establish exactly who used the drawer.
- Record the amount, the cause and everything ruled out.
Work the list in order and stop when you find the cause. Skipping ahead to the explanation you already suspect is how the wrong person ends up answering for a process fault.
Frequently Asked Questions
Is an overage better than a shortage?
No, it is the same control failure pointing the other way. Extra cash usually means a sale was not recorded, change was given short, or a refund was processed without cash leaving. Each of those is a real problem, and treating overages as good luck teaches staff that only shortages matter.
Should a variance be deducted from someone pay?
Employment law in most jurisdictions restricts this sharply, and doing it on a shared drawer is indefensible in any case. Focus on process instead: individual drawers, counted handovers, documented refunds. Take advice locally before any deduction, and never make it a routine response.
What if the variance never explains itself?
Record it as unresolved with all checks listed, then look at the pattern rather than the incident. Persistent unexplained variances almost always trace back to a structural issue such as shared drawers or an incorrectly built expected figure, both of which are covered in cash handling procedures.
Put It Into Practice
Next time a drawer misses, resist the temptation to write it off. Ten minutes spent working the list in order is what turns a recurring mystery into a fixable process fault.
