What Is an Internal Check Fraud?
It happens when an insider, such as an employee, contractor, or person with access to an organization’s financial and accounting system, commits a crime. Perpetrators have intimate knowledge of the company’s operation and payment approval process.
They take advantage of the weakness of the internal issuance system to write bad checks and send money to themselves or an accomplice. It is particularly dangerous because it is hard to detect at the right time.
Common Types of Check Fraud That Take Place Internally
Check Kiting
The person takes advantage of the float time between the two banks and writes checks for an insufficiently funded or non-existent account. They deposit them into another account, which could belong to them or a co-conspirator. This creates an illusion that there is money in the account. They leverage the time gap and withdraw the funds before the rejection of the document.
Check Washing
In this form of fraud, scammers will use a chemical solution or bleach to remove the ink. After washing, they change the crucial information, such as adding a new payee name or a higher amount, and then deposit the check. It will look legitimate to banks or financial institutions, especially if the criminal processes it electronically. It will allow them to cash it without getting caught.
Kickback Schemes
This happens when an employee in a position of authority accepts a bribe. They will issue checks to pay for goods and services that are either overpriced or unnecessary. The supplier will send a portion of the purchase to the employee’s account.
Payroll Fraud
Employees with access to the payroll system will manipulate it to create counterfeit checks for non-existent accounts. They might also inflate their salaries or create duplicate entries for existing employees.
Multiple Payments on Single Invoices
This is common when employees have control over both accounts payable and accounts receivable systems. They can create duplicate checks on the same invoice. They will send one of them to the vendor and deposit the second one, and cash it.

What Should a Company Do After Discovering Internal Check Fraud?
Secure the Accounts
Report check fraud immediately to your financial institution and request that they freeze the compromised account. This will prevent further unauthorized transactions. You must also revoke access for employees to the affected system, including payment infrastructure, bank accounts, and accounting software.
Investigate the Fraud Incident
Conduct an internal audit to track the checks that are part of the fraudulent activity. If needed, hire a forensic accountant or fraud investigator to trace and identify the perpetrator’s methods. Additionally, you must also review the internal controls to determine where they fail. It is possible that the employee has unchecked access to the account, or they did not follow the protocols of the separation of duties. You must also check if there are issues with digital security, such as weak passwords or inadequate encryption.
Notify Relevant Parties
Report check fraud to law enforcement and regulatory bodies. If it involves a large sum of money or violates financial regulations, you will have to report the incident to the Federal Trade Commission. Furthermore, in case you have an insurance provider that covers financial fraud, inform them to begin the claim process.

How Can You Build a Check Fraud-Resistant Culture Within Your Business?
Segregation of Duties
Divide the task and responsibility among different employees to prevent one person from having control over the entire check issuance process. For example, one person should issue the document, and another should approve it. The oversight reduces the temptation to commit fraud. Additionally, in case of fraud, you can trace the steps back to the person responsible for the task and resolve it quickly.
Employee Training
Educate staff on the importance of internal check fraud prevention and how to identify suspicious activity. They must also know the correct procedure to report the crime without the fear of retaliation.

FAQs
Can Internal Check Fraud Affect a Company’s Credit Score?
The direct impact is not immediate, but it does influence the company’s credit score. If business check fraud leads to a significant monetary loss, it will reduce the company’s cash flow and impact its financial health. The reduced liquidity will lead to missed payments on loans, lines of credit, and other obligations. This will negatively impact the credit score. Similarly, if the scam becomes public, lenders will view the company as high-risk. It will lead to high interest rates and reduced credit limits. Both these aspects will lower the credit score.
Can an Employee Commit Check Fraud Without Physically Accessing the Checks?
Yes, they just need access to the accounting software or the banking system to create fake checks. They can change the amount or payee information to forge a fraudulent transaction without needing the physical copy.
Are Digital Checks Less Prone to Internal Fraud Than Paper Checks?
It is not the check type but the system that generates, prints, and mails them that makes them an easy target for scammers to commit criminal activity. Weak access control and a lack of monitoring will allow fraudsters to initiate fraudulent pieces, modify account details, and bypass fraud detection systems.
How Often Should Companies Conduct Internal Audits to Prevent Check Fraud?
This depends on the size, complexity, and risk profile of the business. For example, if you are a small business, you can conduct quarterly or semi-annual audits. The scope will be narrow, focusing on reviewing bank statements and verifying high-risk transactions. However, if you are a large business, you must conduct monthly audits. This will ensure that there is constant monitoring of the business operations, mainly because multiple departments from various locations might be responsible for check processing and payments.
