Well, you have two ways: the traditional way and the new way. Traditional: Hire an accountant or create an accounting department (it all depends on the size of your company). As for the new one, you can just use a payroll service. Both options are good, and each organization decides individually. I work for a company that calculates salaries through
payrollindex.com. I talked to my bosses about why they made this decision, and they said it was more convenient for our company. This way, they guarantee their employee's timely payment of wages and no problems with tax authorities. Because the service does everything following the law.
