Petty cash is a small fund of physical currency, bills and coins, that a business keeps on its premises to pay for minor expenses where writing a check, running a card or processing a reimbursement would cost more effort than the purchase is worth. One person, the custodian, holds the fund in a locked box or drawer, pays out small amounts against written slips, and periodically turns those slips in so the fund can be restored to its original amount. In the accounts, petty cash is an asset. The money spent from it becomes ordinary business expenses, recorded when the fund is replenished.

The amount is set by each business. Funds of a few hundred dollars are typical, and ranges of $100 to $500 are commonly cited. The right size is enough to cover a normal week or month of small outlays without keeping more loose cash on site than the business can afford to lose.

How a Petty Cash Fund Works

The standard method is the imprest system. “Imprest” means the fund is kept at a fixed amount. The cycle has four stages.

1. Establish the fund. The business decides on an amount, say $300, and draws that much from its bank account, usually by a check made out to the custodian or a cash withdrawal. The cash goes into a locked box.
2. Pay out against slips. When an employee needs money for an approved small expense, the custodian pays it and fills out a petty cash slip (also called a voucher) recording the date, amount, purpose, the person receiving the money and an approval signature. The purchase receipt is stapled to the slip.
3. Count and reconcile. At a set interval (weekly or monthly), or whenever the cash runs low, the custodian totals the slips and counts the remaining cash. The two should add up to the imprest amount.
4. Replenish. The custodian takes the slips to the bookkeeper or accountant, who issues enough new cash to bring the fund back to its fixed balance. The slips are canceled (stamped “paid”) so they cannot be submitted again.

The Petty Cash Fund Formula

Three relationships cover nearly every petty cash calculation:

• Imprest balance = cash on hand + total of paid vouchers (when the fund is in balance)
• Replenishment amount = imprest balance − cash counted
• Cash over or short = (cash counted + vouchers) − imprest balance

A negative result in the last formula is a shortage; a positive one is an overage. A shortage means more cash left the box than the slips explain. An overage means the box holds more than it should, often because change was not recorded correctly or a slip was written for more than was paid.

How to Record Petty Cash in Accounting

The Petty Cash ledger balance stays fixed at the imprest amount, and individual purchases are recorded in batches.

Establishing the Fund

When the fund is first set up, cash moves from one asset account to another:

No expense is recorded yet. Total assets are unchanged.

During the Period

Nothing is journalized when the custodian pays out cash. The slips accumulate in the box. Many businesses keep a petty cash book or log, a running record with columns for date, voucher number, description, amount and analysis columns for the expense categories (postage, supplies, travel and so on). At the end of the period, the totals of those columns form a monthly or weekly summary, which becomes the basis for the replenishment entry.

Replenishing the Fund

At replenishment, the bookkeeper debits each expense account for the amounts shown on the slips and credits the bank cash account for the check or transfer that refills the box. The Petty Cash account itself is not touched, because the fund is being restored to the balance it already shows.

Some bookkeepers record the expenses against Petty Cash first (debit expenses, credit Petty Cash) and then record the refill separately (debit Petty Cash, credit Cash). The final result is the same: expenses are recognized, bank cash falls by the amount spent, and Petty Cash returns to its imprest balance.

Handling Overages and Shortages

If counted cash plus slips does not equal the imprest amount, the difference is posted to Cash Over and Short:

• Shortage: debit Cash Over and Short. It behaves like a miscellaneous expense.
• Overage: credit Cash Over and Short. It behaves like miscellaneous income.

The account forces the replenishment entry to balance while keeping the discrepancy visible. Small, occasional differences are normal arithmetic errors. Repeated shortages point to missing slips, unauthorized use or theft and call for investigation.

Changing the Fund Size

The Petty Cash account changes only when the business decides the fund is too large or too small. To increase a $300 fund to $400, debit Petty Cash $100 and credit Cash $100. To reduce it, reverse the entry and return the excess cash to the bank.

Period-End Adjustment

If financial statements are prepared when the fund holds unreplenished slips, those expenses have occurred but are not yet in the ledger. Businesses typically replenish the fund on the last day of the period, or make an adjusting entry, so the expenses land in the correct period on the income statement and the cash balance is not overstated.

Worked Example: Reconciling and Replenishing a Fund

Hypothetical example for illustration only.

A small office runs a $300 imprest fund. At month-end, the custodian finds these slips:

Expected cash in the box: $300.00 − $216.75 = $83.25.

Counted cash: $80.50.

Cash over or short: ($80.50 + $216.75) − $300.00 = −$2.75, a shortage.

Replenishment amount: $300.00 − $80.50 = $219.50.

The replenishment entry:

After the $219.50 goes into the box, it holds $300.00 again, and the Petty Cash ledger balance is still $300.00. Note that the refill amount is based on the cash actually counted, not the slip total. Refilling only $216.75 would leave the fund permanently $2.75 short.

The client lunch shows how entertainment costs fit in. If company policy permits them, they can be paid from the fund but are still recorded in their own expense account, not a general “petty cash expense” bucket. Petty cash is a payment method, not an expense category.

Rules and Controls for Managing Petty Cash

Cash is the asset most exposed to loss, and petty cash bypasses the approval steps that cover checks and card payments. A written policy fills that gap. Common controls include:

• One custodian. A single named person holds the key and is accountable for the fund. A backup is named for absences, with a count done at each handover.
• Separation of duties. The person who issues the replenishment check or transfer is not the custodian. The custodian handles the cash and slips; the bookkeeper or cashier funds the box and makes the entries. Neither can move money and hide it alone.
• Per-transaction limits. A ceiling on any single payment keeps large purchases in the normal purchasing process.
• A list of allowed and banned uses. Typical bans: personal loans or IOUs, cashing personal checks, paying wages or contractors, and splitting a large purchase into several small slips.
• A slip for every payout. The IRS, in its guidance on starting a business and keeping records (Publication 583), recommends using petty cash slips and attaching receipts to document these expenses. A slip without a receipt should carry an explanation and a supervisor’s signature.
• Secure storage. A locked box kept in a locked drawer or safe, with limited key access.
• Surprise counts. Someone other than the custodian counts the fund at unannounced times. Because cash plus slips should always equal the imprest balance, a count can happen any day.
• Timely replenishment. Refilling on a regular schedule keeps slips from piling up and makes gaps easier to trace.

What Petty Cash Is Used For

Petty cash covers small, immediate and often unplanned expenses, where raising a purchase order or waiting for a reimbursement is out of proportion to the amount. Typical examples:

• Small office supplies: pens, tape, batteries, a replacement stapler
• Postage, stamps and courier fees
• Coffee, milk, snacks or water for the office
• Flowers, greeting cards or a small gift for an employee or customer
• A modest meal for a short working session or client visit
• Taxi or ride fare, parking and tolls
• Tips for delivery drivers
• Reimbursing an employee who paid a small work expense out of pocket

The fund is not meant for regular bills, inventory purchases, payroll or anything with its own purchasing process. Using it to make change for customers mixes two separate funds and complicates both reconciliations, so it should be a documented exception.

Petty Cash vs. Cash on Hand, Till Floats and Cash Equivalents

Petty Cash vs. Cash on Hand

“Cash on hand” is the broader term. It usually means currency a business physically holds, such as undeposited receipts, register cash and petty cash. In a wider accounting sense, it can mean all readily available funds, including bank balances. Either way, all petty cash is cash on hand, but most cash on hand is not petty cash.

Petty Cash vs. Cash in Tills

A cash register float, or change fund, is also a fixed amount of currency, but it serves customers. It holds coins and small bills for making change on sales, and it grows during the day as customers pay. Petty cash serves internal spending and only shrinks until it is replenished. Both are reported together within cash on the balance sheet, but they are counted and reconciled separately.

Petty Cash vs. Cash Equivalents

Petty cash is not a cash equivalent. Cash equivalents are short-term, highly liquid investments that convert to a known amount of cash with little risk of value change, such as Treasury bills, commercial paper and money market funds. Petty cash is currency itself.

On the balance sheet, however, petty cash is normally combined into “Cash and cash equivalents” under current assets at its imprest balance. It is rarely shown separately because the amount is immaterial. In the chart of accounts, Petty Cash is a current asset account with a normal debit balance.

Petty Cash vs. Expense Reimbursements and Company Cards

An expense reimbursement pays an employee after the fact, through payroll or accounts payable, and usually requires an expense report. A company card charges the business directly and creates an electronic record of each transaction. Petty cash pays immediately, at the point of need, with a paper trail that depends entirely on the slip.

Advantages and Limitations of Petty Cash

Advantages

• Speed. Cash is available immediately, with no card approval, check run or reimbursement cycle.
• Simplicity. Anyone understands it, and it works where cards are not accepted.
• Fewer small reimbursements. Employees are not left carrying small business costs out of pocket.
• Fewer journal entries. Dozens of tiny purchases become one replenishment entry.

Limitations

• Theft and misuse. Cash leaves no electronic trail. Even with slips, bills can disappear, and a forged or inflated receipt is hard to detect.
• Administrative effort. Counting, filing slips, reconciling and replenishing take time, and in a very small business the owner often ends up doing it.
• Weak records when slips go missing. An expense without a receipt is harder to support for tax and audit purposes.
• Security of the premises. Keeping currency on site carries a risk that small businesses in particular weigh carefully.
• Declining need. Debit and credit cards, prepaid expense cards, digital wallets and payment apps such as PayPal cover many purchases that once required cash, with each transaction traceable. Petty cash still serves vendors and situations where cash is the only practical option.

Some businesses now run a “digital petty cash” arrangement using a prepaid card with a fixed balance. The imprest logic is the same: a set limit, receipts for each charge, and a top-up that matches what was spent.

Why Is It Called Petty Cash?

“Petty” comes from the French petit, meaning small, and came to mean minor in English. One of the earliest recorded uses of the phrase appears in Benjamin Billingsley’s 1678 household bookkeeping guide, Advice to the Women and Maidens of London.

FAQs

The Bottom Line

Petty cash matters to small businesses, office managers and bookkeepers who handle minor purchases that are not worth a check, card charge or reimbursement. Running it as an imprest fund with one custodian, a slip for every payout, separation of duties and surprise counts keeps losses visible and turns many small purchases into one replenishment entry. As cards and payment apps take over more purchases, petty cash remains useful mainly where cash is the only practical option.
