What type of general control can help detect fraud?

Signing for wages serves as a general control that can help detect fraud, particularly in the context of payroll management. By requiring employees to sign for their wages, organizations create a system of accountability and documentation. This process enables the business to verify that the individual receiving payment is indeed the authorized employee, reducing the likelihood of fraudulent activities such as ghost employees or inflated wage claims.

When employees must acknowledge receipt of their wages, it provides a clear record that can be audited. If discrepancies arise, such as payments being made without corresponding signatures, these can be quickly identified during routine checks or audits. This control is particularly important in payroll systems where large sums of money are disbursed, creating opportunities for potential fraud.

In contrast, the other options do not necessarily create oversight or accountability that would help identify fraudulent activities. Increasing marketing efforts, diversifying product ranges, and improving customer satisfaction focus on business growth and customer relations, rather than establishing controls that monitor or detect financial irregularities. Thus, they do not contribute directly to fraud detection in the same way that a signing procedure for wages does.
