An OHoS is essentially an external sales management consultant. Their primary focus is to help improve a company's sales strategy and performance, usually by working with the existing sales team. In some cases, an OHoS can also be responsible for hiring and training new sales staff. While an OHoS can be hired on a project basis, many companies choose to retain them on a ongoing basis in order to ensure that their sales efforts are continuously improving. This arrangement can prove to be very beneficial for businesses, as it allows them to tap into the expertise of an experienced professional without having to commit to a full-time hire.
