Disbursement Fraud Audit Tests: Five Powerful But Simple Ideas

By Charles Hall | Auditing

May 31

You are leading the audit team discussion concerning disbursements, and a staff member asks, “Why don’t we ever perform fraud tests? It seems like we never introduce elements of unpredictability.”

You respond by saying, “Yes, I know the audit standards require unpredictable tests, but I’m not sure what else to do. Any fresh ideas?”

The staff member sheepishly responds, “I’m not sure.” 

You remember a blog post addressing how fraud can sting auditors, and you think, “What can we do?”

Five Disbursement Fraud Tests

Here are five disbursement fraud tests that you can perform on most any audit.

1. Test for duplicate payments

Why test?

Theft may occur as the accounts payable clerk generates the same check twice, stealing and converting the second check to cash. The second check may be created in a separate check batch, a week or two later. This threat increases if (1) checks are signed electronically or (2) the check-signer commonly does not examine supporting documentation and the payee name.

How to test?

Obtain a download of the full check register in Excel. Sort by dollar amount and vendor name. Then investigate same-dollar payments with same-vendor names above a certain threshold (e.g., $25,000).

2. Review the accounts payable vendor file for similar names

Why test?

Fictitious vendor names may mimic real vendor names (e.g., ABC Company is the real vendor name while the fictitious name is ABC Co.). Additionally, the home address of the accounts payable clerk is assigned to the fake vendor (alternatively, P.O. boxes may be used).

The check-signer will not recognize the payee name as fictitious.

How to test?

Obtain a download of all vendor names in Excel. Sort by name and visually compare any vendors with similar names. Investigate any near-matches.

3. Check for fictitious vendors

Why test?

The accounts payable clerk may add a fictitious vendor (one in which no similar vendor name exists, as we saw in the preceding example).

The fictitious vendor address? You guessed it: the clerk’s home address (or P.O. Box).

Pay particular attention to new vendors that provide services (e.g., consulting) rather than physical products (e.g., inventory). Physical products leave audit trails; services, less so.

How to test?

Obtain a download in Excel of new vendors and their addresses for a period of time (e.g., month or quarter). Google the businesses to check for validity; if necessary, call the vendor. Or ask someone familiar with vendors to review the list (preferably someone without vendor set-up capabilities).

4. Compare vendor and payroll addresses

Why test?

Those with vendor-setup ability can create fictitious vendors associated with their own home address. If you compare all addresses in the vendor file with addresses in the payroll file, you may find a match. (Careful – sometimes the match is legitimate, such as travel checks being processed through accounts payable.) Investigate any suspicious matches.

How to test?

Obtain a download in Excel of (1) vendor names and addresses and (2) payroll names and addresses. Merge the two files; sort the addresses and visually inspect for matches.

5. Scan all checks for proper signatures and payees

Why test?

Fraudsters will forge signatures or complete checks with improper payees such as themselves.

How to test?

Pick a period of time (e.g., two months), obtain the related bank statements, and scan the checks for appropriate signatures and payees. Also, consider scanning endorsements (if available).

    Great tips! Another I test I do is look for checks runs on the weekend. All of my clients say they never cut checks on the weekend. It’s quite simple, takes about a minute or two depending on the size of the register. In the Excel check register, I add a column for “day of week”, type in the formula to convert the check date to day of the week, copy it down the column, done. I can use the sort function to easily see if any checks were cut on the weekend. You can also use the same test to see if checks are cut on a day outside of the client’s policy, i.e. if your client’s policy is that they only cut checks on a certain day(s) of the week, you can quickly verify this.
