Types of E-Commerce Business Models:

Electronic commerce can be classified into four main categories. The basis for this simple classification is the parties that are involved in the transactions. So the four basic e-commerce models are as follows,

1. Business to Business

This is Business to Business transactions. Here the companies are doing business with each other. The final consumer is not involved. So the online transactions only involve the manufacturers, wholesalers, retailers etc. Business to business (B2B) is referred to a business that is conducted between companies, rather than between a company and individual consumers.

2. Business to Consumer

The term business-to-consumer (B 2 C) refers to the method of selling products and services directly connecting customers who are the end-users of its products or services. Business to Consumer. Here the company will sell their goods and/or services directly to the consumer. The consumer will browse their websites and appearance at products, pictures, scan reviews. Then they place their order and the business ships the goods directly on them. Popular examples are Amazon, Flipkart, Jabong, etc.

3. Consumer to Consumer

Consumer to consumer, where the consumers are in direct contact with each other. No company is involved. It helps people sell their personal goods and assets directly to an interested party. Usually, goods traded are cars, bikes, electronics etc. OLX, Quikr etc follow this model.

4. Consumer to Business

C 2 B or Consumer- to- Business is a business model wherever the end customers create product and services that are consumed by businesses and organizations. It is diametrically opposite to the popular conception of B 2 C or Business- to- consumer where the businesses create merchandise and services offered to the tip customers. This is the reverse of B 2 C, it is a consumer to business. So the consumer provides a good or some service to the company. Say for example an IT freelancer who demos and sells his software to a company. This would be a C 2 B transaction.

Advantages of E-Commerce :

• E-commerce provides the sellers with a global reach. They remove the barrier of place (geography). Now sellers and buyers can meet in the virtual world, without the hindrance of location. Faster buying/selling method, as well as easy to get products.
• Electronic commerce will substantially lower the transaction cost. It eliminates many fixed costs of maintaining brick and mortar shops. This allows the companies to enjoy a much higher margin of profit.

· It provides quick delivery of goods with very little effort on part of the customer. Customer complaints are also addressed quickly. It also saves time, energy and effort for both the consumers and the company.

· One other great advantage is the convenience it offers. A customer can shop 24×7. The website is functional at all times, it does not have working hours like a shop.

· Electronic commerce also allows the customer and the business to be in touch directly, without any intermediaries. This allows for quick communication and transactions. It also gives a valuable personal touch.

Disadvantages of E-Commerce :

· The start-up costs of the e-commerce portal are very high. The setup of the hardware and the software, the training cost of employees, the constant maintenance and upkeep are all quite expensive.

· Although it may seem like a sure thing, the e-commerce industry has a high risk of failure. Many companies riding the dot-com wave of the 2000s have failed miserably. The high risk of failure remains even today.

· At times, e-commerce can feel impersonal. So it lacks the warmth of an interpersonal relationship which is important for many brands and products. This lack of a personal touch can be a disadvantage for many types of services and products like interior designing or the jewelry business.

· Security is another area of concern. Only recently, we have witnessed many security breaches where the information of the customers was stolen. Credit card theft, identity theft etc. remain big concerns with the customers.

· Then there are also fulfillment problems. Even after the order is placed there can be problems with shipping, delivery, mix-ups etc. This leaves the customers unhappy and dissatisfied.

E-commerce marketing is that the act of driving awareness and action toward a business that sells its product or service. Electronically-commerce marketers can use social media, digital content, search engines, and email campaigns to attract visitors and facilitate purchases online.
