Direct deposit is one of the most convenient payroll features available in QuickBooks. It allows employers to send employee wages directly to bank accounts without issuing paper checks. This method saves time, improves payroll accuracy, and helps employees receive their payments quickly. However, there are occasions when a direct deposit does not process successfully, creating delays and additional work for both employers and employees.
