Purchasing is the process a business or organization uses to acquire goods or services to accomplish its goals. Although there are several organizations that attempt to set standards in the purchasing process, processes can vary greatly between organizations.
Purchasing is part of the wider procurement process, which typically also includes expediting, supplier quality, transportation, and logistics.
Sales are activities related to selling or the number of goods sold in a given targeted time period. The delivery of a service for a cost is also considered a sale. A period during which goods are sold for a reduced price may also be referred to as a "sale".
The seller, or the provider of the goods or services, completes a sale in an interaction with a buyer, which may occur at the point of sale or in response to a purchase order from a customer. There is a passing of title (property or ownership) of the item, and the settlement of a price, in which agreement is reached on a price for which transfer of ownership of the item will occur. The seller, not the purchaser, typically executes the sale and it may be completed prior to the obligation of payment. In the case of indirect interaction, a person who sells goods or service on behalf of the owner is known as a salesman or saleswoman or salesperson, but this often refers to someone selling goods in a store/shop, in which case other terms are also common, including salesclerk, shop assistant, and retail clerk.
Real income is the income of individuals or nations after adjusting for inflation. It is calculated by dividing nominal income by the price level. Real variables such as real income and real GDP are variables that are measured in physical units, while nominal variables such as nominal income and nominal GDP are measured in monetary units. Therefore, real income is a more useful indicator of well-being since it measures the amount of goods and services that can be purchased with the income. Growth of real income is related to real gross national income per capita growth.
According to the classical dichotomy theory, real variables and nominal variables are separate in the long run, so they are not influenced by each other. In other words, if the nominal starting income was 100 and there was 10% inflation (general rise in prices, for example, what cost 10 now costs 11), then with nominal income of still 100, one can buy roughly 9% less; so if nominal income was not adjusted for inflation (did not rise by 10%), real income has dropped by approximately 9%. But if the classical dichotomy holds, nominal income will eventually go up by 10%, leaving real income unchanged from its original value.
Procurement is the process of locating and agreeing to terms and purchasing goods, services, or other works from an external source, often with the use of a tendering or competitive bidding process. When a government agency buys goods or services through this practice, it is referred to as government procurement or public procurement. The term "procure" may also refer to a contractual obligation to "procure" something, i.e. to "ensure" that the thing is done.
Procurement as an organizational process is intended to ensure that the buyer receives goods, services, or works at the best possible price when aspects such as quality, quantity, time, and location are compared. Corporations and public bodies often define processes intended to promote fair and open competition for their business while minimizing risks such as exposure to fraud and collusion.
E-procurement (electronic procurement, sometimes also known as supplier exchange) is a collective term used to refer to a range of technologies which can be used to automate the internal and external processes associated with procurement, strategic sourcing and purchasing.
Examples of e-procurement include e-auctions, e-tendering, automated issue of purchase orders and related receipting and invoicing processes, internet ordering, use of purchasing cards, and the use of information and networking systems such as electronic data interchange and enterprise resource planning systems.
In economics, willingness to accept (WTA) is the minimum monetary amount that а person is willing to accept to sell a good or service, or to bear a negative externality, such as pollution. This is in contrast to willingness to pay (WTP), which is the maximum amount of money a consumer (a buyer) is willing to sacrifice to purchase a good/service or avoid something undesirable. The price of any transaction will thus be any point between a buyer's willingness to pay and a seller's willingness to accept; the net difference is the economic surplus.
Several methods exist to measure consumer willingness to accept payment. These methods can be differentiated by whether they measure consumers' hypothetical or actual willingness to accept, and whether they measure it directly or indirectly.

In practice, the procurement process is commonly organized into seven steps that provide structure and consistency across purchasing activities.
A broker is a person or entity that arranges transactions between a buyer and a seller. This may be done for a commission when the deal is executed. A broker who also acts as a seller or as a buyer becomes a principal party to the deal. Neither role should be confused with that of an agent—one who acts on behalf of a principal party in a deal.
