Sales skills are hard and soft skills that help a professional successfully sell a company's goods and services to third parties. Organizations that base their business on clients or customers buying their products or services rely on sales professionals to generate transactions constantly.

Hard selling skills are easier to teach and measure and have to do the technical side of a product. Product knowledge is needed as an understanding of why the product works.

Soft skills are sometimes harder to define, but they include how effectively the salespeople relate and communicate with others, especially customers. Critical soft skills have emotional intelligence, communication skills, charisma, confidence, and more. Selling is so people-centric and emphasizes the human element in services.

To sell a product, you usually need to understand the technical side of the product to help the customer see what he wants the product to be available. Then to finish the job and help the customer understand that the technical benefits will not only be the ones he wants but that the product offered is desirable and the right product requires soft skills in presentation, communication, and instilling confidence.
