Final answer:
Routine completion of sales made regularly to target customers is typically handled by Order-Taking Sales Reps, who focus on the administrative side of fulfilling existing orders and maintaining customer relationships.
Step-by-step explanation:
The routine completion of sales made regularly to target customers is typically conducted by Order-Taking Sales Reps. These individuals are responsible for the clerical or office aspect of the sales process, which includes processing regular orders and maintaining ongoing customer relationships. Unlike Field Sales Representatives who actively seek new clients and Key Account Managers who focus on managing relationships with strategic, high-value customers, Order-Taking Sales Reps ensure that existing customers' orders are fulfilled efficiently and effectively. The role can sometimes overlap with Telemarketing Agents who might also take orders over the phone, but Order-Taking Sales Reps have a more routine and administrative focus.
