What Is Petty Cash Management?

Petty cash is a relatively small amount of cash on hand available for employees of a business to make small, non-recurring purchases easily and quickly. While non-cash transactions are increasingly becoming the norm for most transactions, cash is still needed to cover small, “one-off” purchases. This may be for postage, taxi fares, office supplies, or food for an impromptu meeting, for example.

Your business will need to have a petty cash fund for these or similar small expenses, and you will need to have a process in place to properly account for those purchases.

Petty Cash Management Overview

Not surprisingly, petty cash funds are vulnerable to misuse and could even lead to outright fraud.

A petty cash management system helps companies ensure that the funds are used appropriately and the transactions are properly documented. Having such a system in place serves as an internal control to protect the business against theft and fraud, and it supports the larger, general ledger reconciliation process.

How to Set Up a Petty Cash Management System

The process for managing your petty cash fund is commonly referred to as the “imprest system.” This will include a number of essential elements, such as a designated custodian for managing the account, a source of funding, policies and procedures for managing the expenses, and accounting procedures for expense reconciliation.

Appoint a Custodian

The first step in the imprest system is to appoint a petty cash custodian. The custodian will be the primary person in the organization responsible for managing the petty cash.  Designating a custodian establishes accountability and reduces the incidence of error or fraud by minimizing the number of employees who have access to the cash in the fund.

Fund the Account

Also under the imprest system, a balance is predetermined for the petty cash fund. Cash is allocated to the fund in that amount from the company’s checking account, and the balance is maintained as purchases occur.

The petty cash balance should be sufficient to support the amount of activity expected in the account, and will typically be a reflection of the size of the company. Small businesses are just as likely to have a petty cash fund as a large corporation, but the total amount in the fund will vary.

Secure the Funds

Once the cash has been released to the petty cash fund, you will want to secure it, most likely in a lock box, safe, or a locked drawer or file cabinet. Only the custodian and other specifically designated individuals, such as the CFO, may possess the key. This helps ensure accountability and protects against theft or fraud.

Establish Policies

Your company will also want to have a set of policies in place to establish how the petty cash funds are spent and administered. These policies will identify the sort of transactions that qualify as petty cash expenses, and it will establish guidelines for how these business expenses are to be documented.

Record Disbursements

For proper administration and accounting of the petty cash account, the custodian should maintain a log of all disbursements. The log will allow for proper reconciliation of the account at the end of the reporting period when financial statements are prepared.

Require Receipts

In addition to a log, your company’s policies should include a requirement for receipts to be provided for every purchase. These will provide detailed vendor or cash register receipts, which itemize the item or service purchased, the date, and the amount.

Petty cash vouchers should also be required to further document the transaction by providing additional information, like the purpose of the expense, the account, and the individual who is responsible for making the purchase.

Replenish Funds When Low

With active spending, the amount of petty cash will eventually diminish, and the funds should be replenished to support more purchases. At this point, the custodian will request a new check from the company’s bank account in an amount that will return the fund to the original balance.

Receipts and spending should be reconciled before the funds are replenished.

Monitor Spending

All of the above should be closely monitored. Regular tallies of the funds, verification of receipts and vouchers, and reconciliation of expenditures will ensure compliance with company policies and minimize discrepancies in the balance sheet.

This is typically done by someone other than the custodian for proper segregation of duties.

What Are the Challenges with Petty Cash Management?


Petty cash funds can be misused. Having cash in a lock box creates a unique set of challenges, which demands an effective cash management system.

Lack of Attention

With petty cash on hand, there is an increased tendency to spend the money freely without attention to detail. This lack of attention can lead to a missing or inadequate paper trail, and sometimes fraud or theft.

Expenses should also be fully documented and policies followed to ensure that the expenses are in line with the company’s objectives.

Reliance on Custodians

While assigning a custodian to manage a petty cash fund increases accountability, it also has risks. The custodian should be a competent, trustworthy employee in the organization.

The records of petty cash disbursements should also be kept by someone other than the custodian or anyone else who has access to the fund, for proper segregation of duties and to avoid misappropriation of the cash.

Paper-Based Approach

While it is important to have a thorough process in place for documenting the transactions in the petty cash fund, a traditional paper-based approach has many limitations.

Simply put, petty cash expenses lack the immediate record generated by a credit card purchase, for example. Improper or overlooked log entries can lead to errors, and supporting documents like receipts and invoices can be misplaced or overlooked.

How Do You Improve Petty Cash Management?


There are many ways an organization can enhance the management of its petty cash fund to address some of the pitfalls and challenges of a traditional, paper-based approach.

How Does Petty Cash Management Software Work?


The first step an organization can take to improve its petty cash management system is to migrate to a computer based, software approach. Petty cash management software can help your company reduce the incidence of error and misuse by automating the workflow process around petty cash management and providing a centralized repository for storing all the associated documentation.

Software puts controls in place to ensure that petty cash reconciliations are being properly performed. These include:

  • Automating the petty cash reconciliation workflow

  • Ensuring that reconciliations are properly reviewed and approved

  • Maintaining appropriate segregation of duties

Software also provides standardized templates to ensure that petty cash funds are managed consistently across the organization. A centralized repository of all your documentation allows for an easy audit of these records by internal auditors.

When a case of fraudulent use of funds is identified, the software automates the workflow process to enact additional internal controls. Such controls are necessary to prevent any further fraud from occurring.
