Amounts Exactly Twice

Amounts Exactly Twice as much as the other

When an amount is paid to a vendor and it’s exactly double a previous amount paid there is a chance the employee is expensing the double amount, voiding the check, then issuing the correct amount to the vendor and writing a check to themselves for the other half. Example would be an invoice to OzCorp for 1,500 and one month the check is for 3,000. The expense is recorded at 3,000, voided and reissued at 1,500 for OzCorp and 1,500 to a fictitious vendor name where the employee ends up with money. This works well because timing of payment and recording of invoices can always be off and not much attention is paid when its double a payment. However, when this happens when there is no fraud, it means AP is paying off of statements or not getting invoices recorded on time.

How to use it ?

System searches for payments which are exactly twice as much as the other and automatically generates a report containing all identified transactions.

What does our fraud detection analytics software do?

We run more than a dozen separate tests with just the basic data. In fact over half the test for employee, payroll, accounts payable, check, and business fraud are run with just check data, check amount and payee. Here are the tests we run:
