The penalty for the late filing of sales call reports can vary depending on the organization and its policies. In most cases, organizations may impose disciplinary action such as a warning, loss of commission or bonus, or other forms of internal penalties. Some organizations may also have specific financial penalties or policies in place if sales representatives consistently fail to file reports on time. It is best to refer to an organization's specific policies or consult with the respective company's human resources department to determine the exact penalties for late filing of sales call reports.
