Key takeaways

• Establish clear policies by setting spending limits of $50-$100 per transaction, requiring receipts for all purchases, and designating one person as the petty cash custodian to create accountability and prevent misuse.
• Use the imprest system to maintain a fixed fund amount (typically $100-$300 for small businesses) and replenish by adding back exactly what was spent, making reconciliation simple since cash plus receipts should always equal your starting balance.
• Reconcile your petty cash at least monthly by counting remaining cash, totaling all receipts, and verifying these amounts equal your starting balance to catch errors early and deter theft.
• Limit petty cash to appropriate small expenses like office supplies, postage, parking fees, and meeting refreshments while avoiding large purchases, personal expenses, or recurring bills that should go through your regular accounts payable process.

What is petty cash?

Petty cash is a small amount of physical currency that businesses keep on hand to pay for minor expenses quickly. Most small businesses maintain $50–$500 in their petty cash fund.

Common petty cash expenses include:

• Office supplies like pens, paper, and folders
• Postage and shipping costs
• Parking fees and tolls
• Small repairs or maintenance items
• Refreshments for meetings

Petty cash works best for purchases that are too small or urgent to process through your regular accounts payable system.

Why use petty cash?

Petty cash saves time by letting you handle small expenses immediately without processing invoices or waiting for reimbursements. Here's why businesses still use it:

• Speed: Pay for urgent items on the spot without paperwork delays
• Convenience: Handle purchases where cards aren't accepted
• Simplicity: Reduce administrative work for low-value transactions
• Flexibility: Reimburse employees quickly for out-of-pocket expenses

Petty cash works best when you need to cover occasional small purchases. If you're making frequent cash payments, consider whether expense cards or reimbursement software might be more efficient.

Advantages and disadvantages of petty cash

Before setting up a petty cash fund, weigh the benefits against the risks. Here's what to consider:

Advantages of petty cash

• Fast reimbursements: Pay employees back immediately without processing delays
• No card required: Handle purchases at vendors that only accept cash
• Low administrative burden: Skip invoice processing for small, infrequent expenses
• Simple to understand: Most employees can use petty cash without training

Disadvantages of petty cash

• Theft risk: Physical cash is easier to steal than digital payments
• Tracking challenges: Manual record-keeping increases the chance of errors
• Loss potential: Cash can be misplaced or miscounted
• Limited scalability: Managing petty cash gets harder as your business grows

How to set up a petty cash fund

Setting up petty cash correctly prevents problems like missing money, unclear policies, and messy records. Follow these steps to create your fund:

1. Decide how much cash to keep on hand. Start with $100–$200 for most small businesses. Increase the amount if you make frequent small purchases.
2. Designate a petty cash custodian. Choose one person to manage the fund, hand out cash, and collect receipts. This creates accountability.
3. Withdraw cash from your business bank account. Use a check or withdrawal slip so you have a paper trail.
4. Record the initial fund in your accounting system. Debit your petty cash account and credit your bank account for the withdrawal amount.
5. Create a petty cash log. Use a spreadsheet or petty cash book to track every transaction. Include columns for date, description, amount, and running balance.
6. Establish clear policies. Set spending limits, require receipts, and define what expenses are allowed. Put these rules in writing.

How does petty cash work?

Petty cash works in a simple cycle: set up the fund, spend from it, track expenses, and replenish when needed. Here's how each phase works:

Setting up the fund

Most businesses keep $100–$500 on hand, depending on how often they need cash. When you create the fund, record a debit to your petty cash account and a credit to your bank account.

Spending and tracking

When employees make small purchases, they bring receipts to the designated custodian. The custodian logs each expense in a petty cash book or spreadsheet and reimburses the employee.

Some businesses give employees cash upfront for planned purchases. Either way, receipts are required.

Replenishing the fund

When cash runs low, the custodian tallies receipts against the remaining balance. If everything balances, the bookkeeper withdraws more cash from the bank and records the expenses to the correct accounts.

For solo business owners

If you run your business alone, you handle all these steps yourself: handing out cash, collecting receipts, tracking expenses, and updating your records. Diligent tracking is a must, as the IRS requires you to pay self-employment tax if your net earnings from self-employment are $400 or more. See IRS Publication 583 for details.

What expenses should you use petty cash for?

Clear spending guidelines prevent misuse and make tracking easier. Define which expenses are appropriate before employees start using the fund.

Here are examples of expenses that work well with petty cash:

Appropriate petty cash expenses

• Office supplies: Pens, paper, folders, tape, and similar items
• Postage and shipping: Stamps, small package fees, and courier tips
• Parking and tolls: Fees for business-related travel
• Minor repairs: Small fixes like replacing a broken lamp or buying cleaning supplies
• Meeting refreshments: Coffee, snacks, or lunch for client meetings
• Emergency supplies: Items needed urgently when normal ordering isn't possible

Expenses to avoid paying with petty cash

• Large purchases: Anything over your set limit (typically $50–$100)
• Personal expenses: Items not related to business operations
• Recurring bills: Subscriptions, utilities, or regular vendor payments
• Inventory: Stock for resale that should go through accounts payable
• Anything needing an audit trail: Purchases that require documentation for compliance

Best practices for managing petty cash

Strong controls prevent theft, reduce errors, and make reconciliation easier. Follow these practices to keep your petty cash fund secure:

Keep your petty cash fund small

Limit your fund to what you need for one–two weeks of expenses. Smaller amounts reduce your risk if cash goes missing and make discrepancies easier to spot.

Require receipts for all transactions

No receipt, no reimbursement. This rule creates accountability and gives you documentation for tax purposes. If an employee loses a receipt, have them write a signed note explaining the purchase.

Designate one person as custodian

Assign one employee to manage the fund. When one person is responsible, it's easier to track who handled the cash and when.

Use the imprest system

The imprest system keeps your fund at a fixed amount. When you replenish, you add back exactly what was spent. This makes reconciliation simple: cash on hand plus receipts should always equal your starting balance.

Store cash securely

Keep petty cash in a locked box or drawer. Limit access to the custodian and one backup person. Never leave cash unattended or in an unlocked location.

Set spending limits

Cap individual transactions at $50–$100. Larger purchases should go through your regular accounts payable process where they're easier to track and approve.

Conduct regular audits

Count the cash and verify receipts at least monthly. Surprise audits help catch problems early. If the balance doesn't match, investigate immediately.

How to record petty cash

Recording petty cash means documenting every transaction so your books stay accurate and you have proof for tax time. For example, the Social Security Administration provides credit for self-employment income only when it's reported on a timely filed tax return, making accurate records essential. See IRS Publication 583 for more information. Here's what you need to track:

• Petty cash voucher: Note the expense, its business purpose, and the employee's name if you're reimbursing them. Attach the receipt whenever possible.
• Petty cash book or spreadsheet: Track every expense and replenishment to maintain an accurate running balance.
• General ledger entry: Record expenses as credits to petty cash and debits to the appropriate expense accounts. For example, $20 spent on pencils means credit petty cash $20 and debit office supplies $20.

Example of petty cash book or spreadsheet format

A petty cash book is a simple log that tracks every transaction in your fund. Here's an example format:

How to reconcile petty cash

Reconciling petty cash means verifying that your remaining cash plus receipts equals your starting balance. Regular reconciliation catches errors and deters theft. Follow these steps:

1. Count the remaining cash. Record the exact amount in your petty cash box.
2. Add up all receipts. Total every receipt collected since your last reconciliation.
3. Verify the balance. Cash on hand plus receipt totals should equal your fund's starting amount. For example, if you started with $200 and have $45 in cash, your receipts should total $155.
4. Investigate discrepancies immediately. If the numbers don't match, review recent transactions, check for missing receipts, and talk to the custodian.
5. Record the reconciliation. Document the date, amounts, and any discrepancies in your petty cash log.
6. Replenish the fund. Withdraw cash to bring the fund back to its starting balance. Record the replenishment in your accounting system.

FAQs on managing petty cash

Here are answers to common questions about petty cash management.

How much petty cash should I keep on hand?

Most small businesses keep $100–$300 on hand. Start with enough to cover one–two weeks of typical small expenses, then adjust based on how quickly you use it.

What should I do if an employee loses a receipt?

Have the employee write and sign a note describing the purchase, amount, date, and business purpose. Use these exceptions sparingly and track them to spot patterns.

How often should I reconcile petty cash?

Reconcile at least once a month, or more frequently if you have high transaction volume. Surprise audits every few months help deter misuse.

Can I use petty cash for any business expense?

No. Petty cash works best for small, infrequent purchases under $50–$100. Larger expenses, recurring bills, and inventory should go through your regular accounts payable process.

What are signs that petty cash is being misused?

Watch for frequent shortages, missing receipts, vague expense descriptions, or the same employee consistently handling discrepancies. Regular audits and clear policies help prevent these issues.
