Duplicate Payments

  • Vendor payments same vendor same amount
  • Vendor payments same amount same day

Employee with control over accounts payable and the checks can submit an invoice for payment twice. Then they alter the actual check to reflect a different payee. The system may show two checks went to Globex, but only one really did. The other check was written for “cash” and cashed by the employee.

How to use it ?

System searches for payments made on the same day for the same amount with different vendors names. Employee may cut the same check twice and alter the payee in the system to hide the fraud.
