Understanding and Managing Petty Cash System: Types and Best Practices
Running a business involves managing countless small expenses each day. From restocking office supplies to covering last-minute transportation costs, these minor expenses are essential to keep operations running smoothly. However, relying on reimbursement systems to handle such costs often creates delays, burdens employees with paperwork, and adds inefficiencies to the process.
For these scenarios, petty cash systems provide a practical alternative. They allow businesses to make immediate, small payments without lengthy reimbursement procedures. Yet, while petty cash simplifies certain transactions, it also comes with its own challenges—such as security risks, lost receipts, and time-consuming reconciliations.
This guide explores how to implement and manage a petty cash system effectively, covering its types, best practices, and modern solutions like corporate cards and digital tools that address traditional pitfalls, making expense management more efficient and transparent.
What is Petty Cash?
Petty cash is a small fund of cash that businesses keep on hand to cover minor, everyday expenses that aren’t practical to pay through bank transfers or company cheques.
This fund allows employees or departments to handle immediate, low-value purchases without going through lengthy reimbursement processes.
Typically, petty cash is used for:
- Office supplies (pens, paper, sticky notes)
- Employee refreshments (coffee, tea, snacks)
- Small maintenance expenses (replacing light bulbs, minor repairs)
- Transportation costs (local cab fares, parking fees)
- Other incidental expenses that keep daily operations running smoothly
With a clear understanding of what petty cash is, let’s see why having a petty cash system is essential for smooth and efficient business operations.
Why Businesses Need Petty Cash?
In any business, handling minor expenses efficiently can be just as important as managing larger ones.
Here’s why petty cash is essential for businesses of all sizes:
- Quick access for minor expenses: Businesses often have small but necessary expenses like office supplies or local travel costs. Without petty cash, these small costs might require lengthy approval processes, creating unnecessary delays.
- Reduces reimbursement delays: Larger expenses typically require purchase orders and invoices, but for smaller purchases, petty cash allows for simple, direct payments, keeping things moving smoothly.
- Supports employee satisfaction: By reducing the need for employees to cover small expenses from their own pockets and wait for reimbursement, petty cash builds trust and improves morale.
- Ensures continuity during emergencies: For unexpected needs—such as a light bulb replacement during a presentation or last-minute supplies—a petty cash fund offers a quick solution without disrupting business activities.
Now that we understand the importance of petty cash in handling day-to-day expenses, let’s explore the different types of petty cash systems.
Types of Petty Cash Systems
Choosing the right petty cash system depends on your business size, spending patterns, and the level of control you want over minor expenses.
Each type of petty cash system has its own structure and best-use scenario, so let’s break down the main types commonly used in business:
1. Imprest System
The imprest system is the most popular petty cash system due to its simplicity and control. In this system, a fixed amount is allocated for petty cash, and as expenses are made, they are deducted from this set amount. When the fund runs low, it’s replenished back to the original balance.
Key Features:
- Fixed fund: A designated amount is assigned for petty cash.
- Reconciliation and replenishment: At the end of a period (usually monthly), the remaining cash and receipts are reconciled, and the fund is topped up to its initial amount.
- Accountability: This system provides clear oversight, as every transaction must be documented.
Best for businesses of all sizes looking for a simple, controlled way to manage minor expenses.
2. Ordinary System
In the ordinary system, petty cash doesn’t operate with a fixed balance like in the imprest system. Instead, the fund is topped up based on actual expenses and needs rather than a set replenishment schedule. This allows for more flexibility, but it also requires meticulous tracking.
Key Features:
- Flexible fund: Amounts vary based on actual usage, allowing businesses to adjust petty cash amounts based on needs.
- On-demand replenishment: The fund is refilled as needed, not necessarily at a set period.
- Higher risk of discrepancies: With no fixed fund balance, it requires close tracking to avoid errors or misuse.
Best for small businesses or departments with unpredictable spending needs.
3. Analytical System
The analytical system is a more detailed and categorised approach to petty cash. Here, expenses are categorised by type, such as office supplies, travel, refreshments, etc.Â
This system is particularly useful for larger organisations or those that require a deeper analysis of petty cash expenses.
Key Features:
- Expense categorisation: Expenses are logged into specific categories for easier analysis and budget tracking.
- Enhanced reporting: Provides insights into spending patterns by category, helping identify areas of high spending.
- Complex tracking: While it provides more data, it requires more detailed record-keeping.
Best for larger businesses or those with complex petty cash needs, looking for insights into specific spending areas.
Types and Formats of Petty Cash Books
A petty cash book is a record that tracks all transactions made from the petty cash fund. It helps businesses organise minor expenses, maintain transparency, and ensure accountability.
There are different types of petty cash books suited to different needs, depending on the level of detail and the nature of the business’s expenses. Here’s a breakdown of the main types and formats:
1. Columnar Petty Cash Book
- This is the basic format, ideal for businesses with simple petty cash needs.
- Each entry includes essential information such as the date, amount, purpose, and balance.
- It’s easy to maintain and provides a clear record of all petty cash expenses.
- Suitable for smaller businesses with fewer, straightforward transactions.
2. Analytical Petty Cash Book
- This format is more detailed, with separate columns for different expense categories (e.g., office supplies, travel, refreshments).
- It allows businesses to see where funds are being spent the most and can help in budgeting.
- Suitable for larger businesses or those with more complex expense needs.
Format of a Petty Cash Book
The format of a petty cash book can vary based on the level of detail needed. Here’s a look at common elements included in both columnar and analytical petty cash books:
- Date: The date of each transaction.
- Particulars: A brief description of the expense (e.g., "Office Supplies" or "Travel").
- Voucher No.: A unique identifier for each transaction, usually linked to a receipt or invoice.
- Amount Paid: The amount withdrawn for the expense.
- Balance: The remaining balance in the petty cash fund after the expense is recorded.
- Category (in Analytical Books): For analytical books, a category column is added for easy tracking of different types of expenses.
Now that we’ve covered petty cash books and their formats, let’s move on to setting up an efficient petty cash system for your business.
How to Set Up a Petty Cash Management System?
Establishing a petty cash system is crucial for managing small, everyday expenses in an organised and transparent way.Â
A well-designed system ensures that petty cash is used appropriately, tracked accurately, and replenished regularly, all while reducing the risk of errors and misuse.
In the following steps, we’ll cover everything from choosing the right petty cash amount to setting up policies, recording transactions, ensuring compliance, and the best practices!
Step 1: Appoint a Petty Cash Custodian
The first essential step in setting up a petty cash system is to appoint a Petty Cash Custodian.Â
This person is responsible for overseeing and managing the petty cash fund, ensuring that all transactions are authorized, recorded accurately, and supported with necessary documentation.
Key Responsibilities of a Petty Cash Custodian:
- Authorizing expenses: The custodian checks if expenses align with company policies and fall within permitted categories.
- Distributing cash: For each approved expense, the custodian issues the required cash to the employee, ensuring accurate distribution.
- Record-keeping: Every transaction should be logged with details like date, purpose, amount, and the recipient’s name to maintain accurate records.
- Collecting receipts: Receipts for each expense are collected, verified, and filed, ensuring a clear audit trail for all petty cash transactions.
- Reconciling funds: The custodian periodically reviews and reconciles the cash on hand with recorded transactions to prevent discrepancies.
Having a dedicated custodian keeps your petty cash system well-organized and reliable.
Step 2: Establish Clear Policies and Controls
After appointing a custodian, the next step is to create clear, straightforward policies and controls for using petty cash.
These policies guide employees on what is considered an eligible petty cash expense and outline how to access funds. Setting these guidelines streamlines the petty cash process and also helps avoid confusion, misuse, and errors.
Key Elements of Petty Cash Policies and Controls:
- Define eligible expenses: List the types of expenses that can be covered by petty cash, such as:
- Office supplies (pens, notepads)
- Minor repairs
- Employee travel costs (local transportation fares)
- Refreshments for meetings
- Any expense outside of this list should not be covered by petty cash.
- Set spending limits: Establish a maximum amount that can be withdrawn for each expense (e.g., AED100 per transaction). This helps prevent overuse and ensures petty cash is used for minor costs only.
- Approval requirements: Require that all expenses be approved by the custodian or a designated supervisor before funds are distributed.
- Documentation and receipt requirements: For every transaction, the employee should provide a receipt detailing the expense amount, date, and purpose. These receipts should be submitted to the custodian to create a clear paper trail and support accurate record-keeping.
- Regular reconciliation schedule: Schedule regular reconciliation checks, such as weekly or monthly, to ensure the physical cash on hand matches the recorded expenses.
- Define roles and responsibilities: Outline the responsibilities of the custodian and any other personnel involved, such as approving managers or finance staff.Â
By establishing these policies, you set a standard for how petty cash is handled, which helps in maintaining both transparency and accountability.
With policies and controls in place, the next step is to set up record-keeping and documentation practices that support accurate and organised tracking of each petty cash transaction.
Step 3: Securing the Petty Cash Fund
Ensuring the safety of your petty cash fund is essential for preventing loss, theft, and misuse. Since petty cash is often handled in physical currency, it's crucial to establish secure storage practices.
Key Practices for Securing Petty Cash:
- Choose a safe storage location
- Store the petty cash in a locked drawer, safe, or lockbox that is kept in a secure, designated area within the office.
- Only the custodian or authorised personnel should know the location and have access to the key or combination.
- Restrict access
- Limit access to the petty cash fund to the custodian and one or two backup personnel if necessary. This restriction reduces the chances of unauthorised withdrawals and keeps the fund under tight control.
- Keep a record of anyone who accesses the cash for added security.
- Use a petty cash log
- A petty cash log is a record that tracks every transaction from the fund.
- Regularly updating the petty cash log helps ensure all cash movements are documented and accounted for.
- Implement security protocols
- Consider additional security measures such as surveillance cameras in the storage area or periodic surprise audits to monitor petty cash access and usage.
- Conduct regular audits
- Schedule periodic internal audits of the petty cash fund to review cash levels, transactions, and compliance with policies. This adds an extra layer of oversight, ensuring the funds are managed responsibly.
By putting these security practices in place, you safeguard your petty cash fund from potential risks and ensure only authorised transactions take place.
With the fund securely stored and access limited, the next step is to ensure every transaction is accurately recorded and documented for clear tracking and accountability.
Step 4: Recording Transactions and Keeping Receipts
Accurate record-keeping is crucial for tracking petty cash and ensuring it’s used responsibly. Documenting every transaction and storing receipts creates a clear audit trail, making it easier to manage funds, reconcile accounts, and maintain financial transparency.
How to Record Transactions Effectively:
- Use a petty cash log: Set up a petty cash log—either digitally or on paper—to record each transaction. Key details to include:
- Date of transaction
- Amount spent
- Purpose or description of the expense
- Receipt or voucher number
- Remaining balance after each transaction
Issue vouchers: For each transaction, issue a petty cash voucher. This is a form that tracks the following:
- Amount withdrawn
- Purpose of the expense
- The signature of the person receiving cash vouchers makes reconciliation easier and adds another layer of accountability.
- Require receipts for every expense: Always collect receipts for each petty cash expense. Store these with the petty cash log or attach them to corresponding vouchers for easy reference.Â
- Regularly reconcile the log: Periodically review and reconcile the petty cash log against the actual cash on hand and the collected receipts. This helps spot any discrepancies early and maintains accuracy.
By establishing a consistent, structured process for documenting every petty cash transaction, you protect the integrity of your fund and simplify financial reporting.
With every transaction accurately recorded and supported by receipts, the next step is to ensure timely replenishment to keep operations running smoothly. Let’s move on to the final step!
Step 5: Replenishing the Fund
Replenishing the petty cash fund is essential for maintaining a steady flow of small expenses. This step involves calculating the total expenses since the last replenishment, ensuring documentation is complete, and restoring the fund to its original amount.
How to Replenish the Petty Cash Fund:
- Calculate the replenishment amount: Start by totalling all expenses recorded in the petty cash log since the last replenishment. This amount should match the sum of the vouchers and receipts collected.Â
The replenishment amount will equal the original petty cash fund minus the remaining cash balance.
- Review documentation: Check that all vouchers and receipts are properly documented and match the log entries.Â
Ensure every expense is accounted for with a corresponding receipt or voucher, as this will help keep records accurate and prevent errors.
- Request funds: Prepare a replenishment request and submit it to the finance or accounting department. This request should include:
- Total amount needed to bring the fund back to its initial balance
- Summary of all transactions since the last replenishment
- Supporting receipts and vouchers for each expense
- Record the replenishment in the petty cash log: Once the fund is replenished, update the petty cash log to reflect the new cash balance.Â
Be sure to enter the date, amount, and purpose of the replenishment. This helps maintain an accurate, up-to-date record of all petty cash activities.
- Ensure proper approval: Have the replenishment request approved by the appropriate personnel to reinforce internal controls. This extra step of oversight helps maintain financial transparency and accountability.
By regularly replenishing your petty cash fund, you can keep daily operations smooth and ensure funds are always available for small, necessary expenses.
With your petty cash system now fully set up, it's clear that managing petty cash requires precision—but even the best systems can face challenges.Â
Let’s explore the common obstacles businesses encounter and how to solve them effectively.

With built-in categorisation features, we ensure that all your expenses are neatly organised and readily accessible, giving you a comprehensive view of your financial data. - Lost or Misplaced Receipts
