3 Ways to Limit ACH Fraud Exposure

Three Ways to Limit ACH Fraud Exposure

Fraud can be a major threat for any business. Altering or creating fictitious financial transactions and/or documents can make it easy for a criminal to drain funds from your company. Fraud committed against company bank accounts can occur in many ways, including unauthorized checks, wire fraud and ACH fraud.

ACH stands for Automated Clearing House, a nationwide electronic funds-transfer system, which provides for fund transfers between banks and other financial institutions. The ACH network has made transferring funds quick and easy; yet like many payment vehicles, ACH is not immune to the possibility of fraud.

ACH fraud occurs when an account is accessed for unauthorized ACH payments or withdrawals. While a variety of tools are available, a criminal can commit ACH fraud by having access to just two pieces of information: your business checking account number and your bank routing number.

With that information in hand, a criminal can use those numbers to make a payment for goods or services, either by phone or online. The most common ACH fraud attempts are misrepresentation of a business and unauthorized use of business bank accounts. By the time you realize what has happened, the criminals have often disappeared – leaving you to clean up the financial mess.

Fortunately, guarding against ACH fraud can be easy:

  • ACH blocks. One of the simplest ways to help prevent ACH fraud is to place an ACH block on your accounts. This block will not automatically reject transactions; in each case you will be required to review and approve the transaction before it can be completed. Effectively, an ACH block eliminates the possibility of automatic or non-reviewed transactions.
  • One-time authorization. A one-time authorization is just that: you authorize a single transaction by providing the company identification information and the amount of that transaction. The bank verifies the transaction with the information you provide and processes that transaction but no others.
  • Authorized-user list. If you have transactions that will occur on a regular basis with a finite list of other parties, you can create an authorized-user list. You can also specify dollar amounts or limits, date ranges and recurring or one-time use. If a request is received from a company not on the list (or falling outside the other parameters you set) the transaction is rejected or placed on hold for you to review.

Setting up an effective ACH fraud prevention system with your bank provides a number of benefits:

  • Losses are minimized since you can prevent unauthorized transactions before they take place.
  • Errors are minimized since fraud-control tools identify transactions that do not meet your pre-established criteria and also identify misrouted transactions or incorrect dollar amounts.
  • Cash flow is improved while security risks decrease.
  • Preventing losses saves time and effort associated with recovering those funds.

In short, you can enjoy the benefits of ACH transactions while helping keep your company safe from fraud.

Beyond ACH Fraud

You can also set up internal controls to prevent fraudulent behavior that may be initiated internally, that is…by your employees. For example, one effective way to help control the transfer of funds is to create a dual approval system: one employee initiates a payment or debit transaction, and another is required to approve the release or acceptance of that transaction. That way, no one person is in control of the overall process. In fact, putting a system of checks and balances in place makes sense for any financial function.

Additionally, make sure that the computers used to store or access financial information – including ACH transactions – are free from viruses and malware. Use strong passwords, change passwords often and limit the use of your financial systems to only those individuals who need to use them. One of the best ways to prevent employee fraud is to limit the number of individuals who are in a position to commit fraud.
