Do you give your employees the option of directly depositing their paychecks into their bank accounts? If not, why not? It's easy to set up and a nice perk.
Simply ask your payroll processing company for their standard form. Each employee will complete the form and attach a voided check or savings account deposit slip. Your company's bookkeeper, controller, or accountant will also need to submit a form to your payroll processor with your company's bank account information.
