e-commerce (electronic commerce or EC)

Contributor(s): Brian Holak and Ben Cole

E-commerce -- electronic commerce or EC -- is the buying and selling of goods and services, or the transmitting of funds or data, over an electronic network, primarily the internet. These business transactions occur either as business-to-business, business-to-consumer, consumer-to-consumer or consumer-to-business.

The terms e-commerce and e-business are often used interchangeably. The term e-tail is also sometimes used in reference to transactional processes for online shopping.

History of e-commerce

The beginnings of e-commerce can be traced to the 1960s, when businesses started using Electronic Data Interchange (EDI) to share business documents with other companies. In 1979, the American National Standards Institute developed ASC X12 as a universal standard for businesses to share documents through electronic networks.

After the number of individual users sharing electronic documents with each other grew in the 1980s, the rise of eBay and Amazon in the 1990s revolutionized the e-commerce industry. Consumers can now purchase endless amounts of items online, from e-tailers, from typical brick-and-mortar stores with e-commerce capabilities, and from one another.

Types of e-commerce

Business-to-business (B2B) e-commerce refers to the electronic exchange of products, services or information between businesses rather than between businesses and consumers. Examples include online directories and product and supply exchange websites that allow businesses to search for products, services and information and to initiate transactions through e-procurement interfaces.

In 2017, Forrester Research predicted that the B2B e-commerce market will top $1.1 trillion in the U.S. by 2021, accounting for 13% of all B2B sales in the nation.

Business-to-consumer (B2C) is the retail part of e-commerce on the internet. It is when businesses sell products, services or information directly to consumers. The term was popular during the dot-com boom of the late 1990s, when online retailers and sellers of goods were a novelty.

Today, there are innumerable virtual stores and malls on the internet selling all types of consumer goods. The most recognized example of these sites is Amazon, which dominates the B2C market.

Consumer-to-consumer (C2C) is a type of e-commerce in which consumers trade products, services and information with each other online. These transactions are generally conducted through a third party that provides an online platform on which the transactions are carried out.

Online auctions and classified advertisements are two examples of C2C platforms, with eBay and Craigslist being two of the most popular of these platforms. Because eBay is a business, this form of e-commerce could also be called C2B2C -- consumer-to-business-to-consumer.

Consumer-to-business (C2B) is a type of e-commerce in which consumers make their products and services available online for companies to bid on and purchase. This is the opposite of the traditional commerce model of B2C.

A popular example of a C2C platform is a market that sells royalty-free photographs, images, media and design elements, such as iStock. Another example would be a job board.

Business-to-administration (B2A) refers to transactions conducted online between companies and public administration or government bodies. Many branches of government are dependent on e-services or products in one way or another, especially when it comes to legal documents, registers, social security, fiscals and employment. Businesses can supply these electronically. B2A services have grown considerably in recent years as investments have been made in e-government capabilities.

Consumer-to-administration (C2A) refers to transactions conducted online between individual consumers and public administration or government bodies. The government rarely buys products or services from citizens, but individuals frequently use electronic means in the following areas:

  • Education -- disseminating information, distance learning/online lectures, etc.
  • Social Security -- distributing information, making payments, etc.
  • Taxes -- filing tax returns, making payments, etc.
  • Health -- making appointments, providing information about illnesses, making health services payments, etc.

Disruption to physical retail

Given the stratospheric rise in e-commerce in recent years, many analysts, economists and consumers have debated whether the online B2C market will soon make physical, brick-and-mortar stores obsolete. There's little question that online shopping is growing at a significant rate.

Researchers estimated a 15% growth in U.S. sales and total value for online shopping between 2016 and 2017, while offline shopping only saw a 4.5% increase. But offline shopping still dwarfs online sales.

According to the U.S. Census Bureau and the Department of Commerce, e-commerce sales in the first quarter of 2018 accounted for only 9.5% of total sales, and many people prefer shopping at physical stores.

Research from BigCommerce has found that Americans are about evenly split on online versus offline shopping, with 51% of Americans preferring e-commerce and 49% preferring physical stores. However, 67% of millennials prefer shopping online over offline. According to Forbes, 40% of millennials are also already using voice assistants to make purchases, with that number expected to surpass 50% by 2020.

An example of the impact e-commerce has had on physical retail is the post-Thanksgiving Black Friday and Cyber Monday shopping days in the U.S. According to Rakuten Marketing data, in 2017, Cyber Monday -- which features sales that are exclusively online -- saw 68% higher revenues than Black Friday -- which is traditionally the biggest brick-and-mortar shopping day of the year.

According to data from ShopperTrak, physical store traffic on Black Friday declined by 1% year over year, and the two-day Thanksgiving-Black Friday period saw a 1.6% decline in traffic. Nearly 40% of sales on Black Friday came via a mobile device, up nearly 10% from the previous year, an indication that e-commerce is becoming m-commerce.

Mobile e-commerce (m-commerce)

M-commerce is a type of e-commerce on the rise that features online sales transactions made via mobile devices, such as smartphones and tablets. M-commerce includes mobile shopping, mobile banking and mobile payments.

Internet Retailer reported that mobile accounted for 30% of all the U.S. e-commerce activities in 2015. In addition, 62% of smartphone users made a purchase online using their mobile device in the last six months of 2017, according to OuterBox.

Mobile chatbots also provide e-commerce opportunities to businesses, allowing consumers to complete transactions with companies via voice or text conversations.

E-commerce applications

E-commerce is conducted using a variety of applications, such as email, online catalogs and shopping carts, EDI, the File Transfer Protocol, web services, and mobile devices. This includes business-to-business activities and outreach, such as using email for unsolicited ads -- usually viewed as spam -- to consumers and other business prospects, as well as sending out e-newsletters to subscribers and SMS -- short message service -- texts to mobile devices. More companies now try to entice consumers directly online, using tools such as digital coupons, social media marketing and targeted advertisements.

The benefits of e-commerce include its around-the-clock availability, the speed of access, the wide availability of goods and services for the consumer, easy accessibility, and international reach. Its perceived downsides include sometimes limited customer service, consumers not being able to see or touch a product prior to purchase, and the wait time for product shipping.

The rise of e-commerce has forced IT personnel to move beyond infrastructure design and maintenance to consider numerous customer-facing aspects, such as consumer data privacy and security. When developing IT systems and applications to accommodate e-commerce activities, data governance-related regulatory compliance mandates, personally identifiable information privacy rules and information protection protocols must be considered.

Government regulations for e-commerce

In the United States, the Federal Trade Commission (FTC) and the Payment Card Industry (PCI) Security Standards Council are among the primary agencies that regulate e-commerce activities. The FTC monitors activities such as online advertising, content marketing and customer privacy, while the PCI Council develops standards and rules, including PCI Data Security Standard compliance, which outlines procedures for the proper handling and storage of consumers' financial data.

To ensure the security, privacy and effectiveness of e-commerce, businesses should authenticate business transactions, control access to resources such as webpages for registered or selected users, encrypt communications, and implement security technologies, such as the Secure Sockets Layer and two-factor authentication.

I think in this article that you have mentioned interchange of data happen among companies also comes under e-commerce. But according to my knowledge it's something coming only under e-business. Because in e-commerce is defined as transaction happen based on money.

  • its evident that organizations which fully embrace the aspect of information technology to effect business transactions tend to be more competitive than those which have not.
  • e-commerce has largely helped many firms to access and penetrate to vital business opportunities.
  • threats to the safety of big amounts of data or traffic including the very vital financial related.
  • threats to trade secretes. organizations tend to rely more on e-resources to execute most of their business operations including internal processes, these may stand a risk of exposure to the wrong public which could compromise a company's' trading strengths.

The biggest risk is about locality where some consumers are located in a remote areas thus finding it difficult to access goods and services easily
Cancel
Goods may be tampered on the way thus leading to theft and even goods being lost during shipping
Cancel
Is it expensive to start e-commerce business?

Thanks Miss Rouse, very good work.
I really think it is important to note that e-commerce exists with or without internet connection due to the fact that there are networks that are non-internet. Good examples are such as Value Added Networks (VAN), Local Area Network (LAN), use of Vending Machines and Mobile Financial Networks.

Excuse me. It is worth noticing that you made a mistake when you talked about C2B, later referring to that type of e-commerce as C2C. It would be great if you could fix that. Thank you!
