If you get dozens of calls after-hours for services and you think that you need a secretary, it may be difficult to get someone to work at that time. You also may not want to hire another employee for your business or force one of your employees to take all the calls when they are on call. Instead, look into getting help from a call service center. This service center can be very beneficial to keep after-hours services and payroll efficient and to help those that need emergency services.
