Sales

Sales is the act of meeting buyers and providing them with a service for a negotiated compensation. It forms an integral part of commercial activity. Selling is a practical implementation of marketing; it often forms a separate grouping in a corporate structure, employing separate specialist operatives known as salespersons (singular: salesperson. Sales is considered by many to be a sort of persuading "art". Contrary to popular belief, the methodological approach of selling refers to a systematic process of repetitive and measurable milestones, by which a salesperson relates his offering of a product of service in return enabling the buyer to achieve his goal in an economic way.[1]
The marketing department's goal is to bring people to the sales team using promotional techniques such as advertising, sales promotion, publicity, and public relations. In most large corporations, the marketing department is structured in a similar fashion to the sales department[citation needed] and the managers of these teams must coordinate efforts in order to drive profits and business success. Driving more customers "through the door" gives the sales department a better chance by ratio of selling their product to the consumer.[4]

Customer service

Customer service (also known as Client Service) is the provision of service to customers before, during and after a purchase.
Its importance varies by product, industry and customer. As an example, an expert customer might require less pre-purchase service (i.e., advice) than a novice. In many cases, customer service is more important if the purchase relates to a “service” as opposed to a “product".
Customer service may be provided by a person (e.g., sales and service representative), or by automated means called self-service. Examples of self service are Internet sites.
Customer service is normally an integral part of a company’s customer value proposition.Customer service may be employed to generate such competitive advantage as a particular service proposition can be harder to copy for competitors.
The implementation of a particular customer service proposition must consider several elements of the organization, including

Bond

In finance, a bond is a debt security, in which the issuer owes the holders a debt and is gratified to repay the principal and interest at a later date, termed maturity. Other provisions may also be attached to the bond issue, such as the obligation for the issuer to offer certain information to the bond holder, or limitations on the behavior of the issuer. Bonds are generally issued for a fixed term longer than ten years. U.S Treasury securities issued debt with life of ten years or more is a bond. New debt between one year and ten years is a note, and new debt less than a year is a bill.

A bond is simply a loan, but in the form of a security, although terminology used is rather different. The issuer is equivalent to the borrower, the bond holder to the lender, and the coupon to the interest. Bonds enable the issuer to finance long-term investments with external funds. Debt securities with a maturity shorter than one year are typically bills. Certificates of deposit or commercial paper are measured money market instruments.
