• Evaluate key internal controls over petty cash, including documentation, authorisation, custody, independent review, and surprise cash counts.

Overview & key concepts

Purpose of petty cash

Petty cash is a small cash fund held on the premises to pay for low-value, routine items that are inefficient to process through normal payment methods. Typical uses include minor stationery, small travel costs, postage, and incidental repairs.

Petty cash is part of cash (an asset). Spending from petty cash creates expenses (or occasionally assets, such as small items of equipment, depending on the entity’s policy). Because petty cash involves physical notes and coins, it requires strong controls to prevent errors and misuse.

The imprest method in one idea

Under the imprest method, management authorises a fixed petty cash float (for example, $500). The fund is topped up periodically so that it returns to the authorised level.

At reconciliation, you are not trying to “prove” every individual payment in the ledger. Instead, you are proving that the fund is intact by showing that the authorised float is represented by a mix of:

• Cash currently in the box, and
• Evidence of authorised payments already made(vouchers), and
• Any other documented items that legitimately explain the cash position.

Voucher meaning (keep terminology consistent)

A voucher is the internal petty cash document that records what was paid, why it was paid, who approved it, and the amount. Where available, a third-party receipt is attached as supporting evidence. In practice, some payments may have no external receipt (for example, parking meters), so strong internal authorisation and clear descriptions become even more important.

Roles and responsibilities of the petty cash custodian

The petty cash custodian is responsible for:

• keeping the fund secure (locked box, controlled access)
• issuing cash only for permitted items and only with proper approval
• preparing a voucher for each payment and attaching evidence where available
• maintaining a petty cash record (date, purpose, amount, coding)
• requesting replenishment and reconciling the fund.

Imprest works best when replenishment is authorised by someone independent of the custodian, and the coding/analysis of vouchers is reviewed.

Core theory and frameworks

Establishing the fund

When the petty cash fund is created:

• DebitPetty cash (asset)
• CreditBank (asset)

This transfers cash from the bank account into a controlled float.

Recording payments: two common approaches

Organisations usually apply one of these approaches:

1. Record expenses when the fund is replenished (common in imprest systems).
2. Individual payments are supported by vouchers but are not posted to the ledger immediately. When replenishment occurs, the vouchers are analysed and expenses are recorded in one combined entry.
3. Record each payment as it occurs.
4. Each payment is posted as:Debit expense / Credit petty cash. Replenishment then restores petty cash:Debit petty cash / Credit bank.

Many exam-style questions assume the first approach because it tests reconciliation, analysis, and the reimbursement calculation. This chapter uses that approach.

Reconciliation process (imprest method)

A practical reconciliation usually follows these steps:

1. Count the cashphysically in the petty cash box.
2. List and total the vouchers, grouped into expense headings.
3. Identify other reconciling itemsthat affect the cash count but are not vouchers, such as:
   • refunds received and kept in the box,
   • IOUs/advances temporarily held (only if permitted and documented) and
   • any authorised float change not yet recorded.
4. Compare to the authorised floatand calculate any shortage or surplus.
5. Investigate differencesand document the outcome.

Handling shortages and surpluses

• Ashortagemeans less cash is present than expected after considering vouchers and other documented reconciling items.
• Asurplusmeans more cash is present than expected.

Many organisations use a cash short/over account as a temporary holding account while differences are investigated. Repeated or material differences should not be routinely written off.

Practical investigation steps include: re-count the cash, re-add voucher totals, check the sequence of vouchers for missing numbers, confirm approvals, trace unusual items to supporting evidence, discuss the issue with the custodian, and escalate where appropriate.

Calculating the reimbursement (imprest method)

The purpose of reimbursement is to bring the petty cash back to its authorised float.

A clear and exam-safe way to compute the bank top-up is to start from what was spent (supported by vouchers), then adjust for cash that entered the box and for any reconciliation difference:

Bank top-up to restore the existing float
= (total vouchers) − (cash received and kept in the box, such as refunds) + (shortage) − (surplus)

A refund kept in the petty cash box reduces the amount needed from the bank because it increases the cash available. A shortage increases the top-up because there is less cash than there should be. A surplus reduces the top-up because extra cash is already present.

Policy note: some organisations require refunds to be banked directly. If a refund is banked (not kept in petty cash), it does not affect the petty cash top-up.

Adjusting the imprest float

If management changes the authorised float, the replenishment payment may also include a float adjustment:

• Increase in float:additional cash is transferred in and petty cash increases.
• Decrease in float:cash is removed from the fund and returned to bank.

Often a single bank payment both replenishes spending and resets the float to the new authorised level.

Journal entries at replenishment (record-at-replenishment approach)

When replenishing petty cash:

• Debitexpense accounts for the voucher totals (analysed by category).
• Debit/Creditcash short/over for any shortage or surplus.
• Debit/Creditpetty cash for any float adjustment (increase/decrease).
• Creditbank for the cash transferred from the bank to petty cash.
• If refunds are retained in petty cash,creditthe relevant expense category (where known and material) or a general expense refund/other income line (where immaterial or unclear).

Worked example

Narrative scenario

XYZ Corporation maintains a petty cash fund using the imprest method, with an authorised float of $500. The petty cash custodian issues cash for authorised items and retains vouchers as evidence (with receipts attached where available).

During the month, the following occurred:

1. Purchased office supplies:$50
2. Minor repairs:$30
3. Travel expenses:$70
4. Refreshments for a meeting:$40
5. Postage stamps:$20
6. Reimbursed an employee for a business lunch:$60
7. Parking fees:$10
8. During reconciliation, a$5 shortagewas identified.
9. A supplier provided a$15 refundfor an earlier overpayment, and the cash was placed back into the petty cash box.
10. Management decided toincrease the petty cash float to $600going forward.

The custodian must reconcile the petty cash fund and prepare the reimbursement request.

Required

• Calculate the total voucher spending for the month.
• Determine the expected cash balance after considering all cash movements.
• Identify and explain any discrepancy between expected and actual cash.
• Calculate the reimbursement required to restore the petty cash fund to thenewfloat level.
• Prepare the journal entries for replenishment and the float adjustment.

Solution

1) Total voucher spending

Total voucher spending = $280.

2) Expected cash balance (before considering the shortage)

Start from the authorised float and reflect all documented cash movements:

• Initial float:$500
• Less vouchers paid out:($280)
• Add refund received into petty cash:+$15

Expected cash (if no discrepancy)
= 500 − 280 + 15
= $235

3) Discrepancy between expected and actual cash

A $5 shortage was identified during the cash count. Therefore:

Actual cash counted
= expected cash − shortage
= 235 − 5
= $230

Explanation: After allowing for the $15 refund placed into the petty cash box, the cash count should have been $235. Only $230 was present, leaving an unexplained $5 shortage to be recorded and investigated.

4) Reimbursement required to restore the float to $600

Step A: Bank top-up to restore the existing $500 float

Bank top-up to restore existing float
= vouchers − refund retained + shortage
= 280 − 15 + 5
= $270

Check: actual cash 230 + 270 = 500

Step B: Increase float from $500 to $600

Additional cash required = 600 − 500 = $100

Total bank payment (single combined reimbursement)
= 270 + 100
= $370

(Direct check: new float 600 − actual cash 230 = 370)

5) Journal entries

Assume expenses are recorded at replenishment (imprest approach). The refund relates to an earlier expense but the original category is not specified, so it is credited to a general “expense refunds” line (if the category is known and material, it should be credited to that expense instead).

Combined entry for replenishment and float increase

• DebitOffice supplies expense ............................................. 50
• DebitRepairs expense .......................................................... 30
• DebitTravel expense ............................................................. 70
• DebitRefreshments expense ................................................. 40
• DebitPostage expense .......................................................... 20
• DebitStaff costs / business meals ....................................... 60
• DebitParking expense .......................................................... 10
• DebitCash short/over (shortage) ....................................... 5
• DebitPetty cash (increase float) ...................................... 100
• CreditExpense refunds received .......................................... 15
• CreditBank ......................................................................370

Accounting equation link (high level)

The replenishment payment is a transfer between two asset balances: bank decreases and petty cash increases by the same amount. On its own, that transfer does not change total assets—it only changes where the cash is held.

The profit impact comes from recognising the month’s petty cash activity: expenses of $280, less the refund of $15, plus the shortage of $5. The net effect on profit (and equity) is a $270 decrease.

That equity decrease reflects the fact that, over the period, cash resources were used up by operating costs (net of the refund) and a small unexplained loss.

Common pitfalls and misunderstandings

• Treating vouchers as ledger balances.Vouchers are evidence of payments already made; they are not assets or receivables.
• Ignoring cash receipts into petty cash.Refunds kept in the box reduce the amount needed from the bank.
• Calculating the shortage/surplus before allowing for reconciling items.Expected cash must reflect all documented cash movements, not only vouchers.
• Crediting bank for the wrong figure.The bank credit equals the cash transferred to petty cash, which may differ from total vouchers when refunds/shortages/surpluses and float changes exist.
• Missing the float adjustment.Increasing the float requires an additional debit to petty cash beyond replenishing the month’s vouchers.
• Writing off differences without review.Frequent shortages suggest weak controls and must be investigated.
• Weak documentation or vague descriptions.Poor evidence undermines both control and accurate expense analysis.
• Lack of independence.The system is weakest when the same person authorises payments, holds the cash, records the analysis, and approves the reimbursement.

Summary and further reading

Petty cash is a practical tool for low-value payments, but it carries higher risk because it is physical cash. The imprest method strengthens control by fixing an authorised float and requiring replenishment based on documented vouchers, supported by evidence where available.

A strong imprest system depends on:

• clear rules on what petty cash can be used for
• vouchers completed properly and authorised
• reconciliation that considers vouchers and other reconciling items (such as refunds)
• correct reimbursement calculations and journal entries, including float adjustments
• independent authorisation and periodic surprise checks.

Further reading can be done in general financial accounting texts covering cash controls, expense recognition, and internal control procedures.

FAQ

Why is the imprest method commonly used for petty cash?

Because it makes control straightforward: the fund is maintained at a fixed authorised level and replenished from supported vouchers. This creates a clear link between cash movements and documentation, helping detect errors and irregularities promptly.

How should a discrepancy found during reconciliation be handled?

First confirm the mechanics: re-count the cash, re-check voucher totals, and review the voucher sequence for missing items. Then confirm approvals and trace unusual items to evidence. If the difference remains, record it in cash short/over and investigate further, escalating where appropriate.

What internal controls matter most for petty cash?

Key controls include restricted access to cash, clear authorisation rules, sequential vouchers, evidence attached where available, independent approval of replenishment, review of expense coding, and surprise cash counts by someone other than the custodian.

How is the imprest float increased or decreased?

To increase the float, transfer additional cash into petty cash and debit petty cash. To decrease it, remove cash from the fund, return it to bank, and credit petty cash. A single bank payment can both replenish spending and adjust the float.

What journal entries are made on replenishment?

Under the imprest approach, expenses are recorded when replenishment occurs: debit the relevant expense accounts based on voucher totals, record any shortage/surplus, adjust petty cash for any float change, and credit bank for the total cash transferred.

How does petty cash affect the financial statements?

Petty cash forms part of cash (an asset). Voucher spending becomes expenses, reducing profit and equity. Refunds reduce expenses (where the category is known and material) or may be shown as a general expense refund/other income line when immaterial or unclear. Shortages reduce profit if written off.

Summary (Recap)

This chapter explained how petty cash is controlled and accounted for using the imprest method. You learned how to reconcile the authorised float to cash on hand and documented payments, how to treat refunds retained in the box, and how shortages and surpluses affect the reimbursement calculation. You also calculated a combined bank payment that both replenishes petty cash and increases the float, prepared the journal entry, and reviewed internal controls and investigation steps that strengthen the system.
