Under-managing sales can lead to 9 hidden costs for a business: 1) Management headaches fall to the CEO without a sales manager, 2) High turnover costs as issues fester and employees quit, 3) Under-performance as nothing gets properly managed, and opportunities are missed, 4) Falling behind industry trends without someone keeping up, 5) Holes in the sales process never get fixed costing money, 6) Only being able to hire experienced and expensive salespeople without proper training.
