Final answer:
To increase sold units, consider CRM systems with marketing automation, sales force automation, and customer data analytics to automate processes and target marketing effectively, leading to more sales.
Step-by-step explanation:
If a customer with only the core Customer Relationship Management (CRM) system wants to increase sold units, I would suggest looking into CRM systems with enhanced features such as marketing automation, sales force automation, and customer data analytics capabilities. These features can help in identifying sales trends, automating sales processes, and targeting marketing efforts more effectively to boost sales. For instance, marketing automation can assist in creating and managing marketing campaigns that are directed at the right audience, which could lead to a higher number of units sold. Similarly, sales force automation can make the sales process more efficient by managing and prioritizing leads, thus potentially leading to more closed deals and increased sales.
