If I want to reach more potential customers, I can choose to extend product lines.

Considering extending the product lines will support sales growth. This way, you can reach even more potential customers. Always look for similar or complementary product lines. For example, if you work in optics, extend your line of lens cleaning products. Consequently, customers will not need to look for other places for these products. And you can get some brilliant ideas from your customers and consumers, so be open to their suggestions! This way, you will be reinforcing the customer-salesperson relationship, too.
