## Understanding E-commerce

As noted above, e-commerce is the process of buying and selling products and services online. But it involves more than simply a buyer and a seller, relying on a vast, often invisible, infrastructure to keep it running.

E-commerce has helped companies (especially those with a narrow reach, like small, local businesses) gain access to a wider market by providing cheaper and more efficient sales and distribution channels for their products or services.

While some businesses exist entirely online, others straddle the real and virtual worlds. Target ([TGT](https://www.investopedia.com/markets/quote?tvwidgetsymbol=TGT)), for example, is one of many giant retailers that has supplemented its [brick-and-mortar](https://www.investopedia.com/terms/b/brickandmortar.asp) presence with an online store that allows customers to purchase everything from clothes and coffeemakers to toothpaste and action figures without leaving their homes.

At the other end of the scale spectrum, individual sellers increasingly engage in e-commerce transactions via their own personal websites. And digital marketplaces like [eBay](https://www.investopedia.com/articles/markets/042815/how-ebay-makes-its-money-ebay.asp) and Etsy serve as exchanges where multitudes of buyers and sellers can come together and do business.

> E-commerce can be thought of as a digital version of mail-order catalog shopping, which once revolutionized retailing in its own way.

## History of E-commerce

Most of us have shopped online for something at some point, which means we've taken part in e-commerce. So it goes without saying that e-commerce is everywhere. But very few people may know that e-commerce has a history that predates the internet.

E-commerce actually goes back to the 1960s, when companies used an electronic system called the Electronic Data Interchange to facilitate the transfer of documents. It wasn't until 1994 that the very first transaction took place. This involved the sale of a CD between friends through an online retail website called NetMarket.

The industry has evolved rapidly since then, with companies like [Alibaba](https://www.investopedia.com/articles/investing/121714/how-does-alibaba-make-money-simple-guide.asp) and [Amazon](https://www.investopedia.com/how-amazon-makes-money-4587523) becoming household names around the world. The introduction of free shipping, which, at least on the surface, reduces costs for consumers, has also helped increase the popularity of the e-commerce industry.

## Advantages and Disadvantages of E-commerce

### Advantages

E-commerce offers buyers and sellers a number of advantages:

*   **Convenience**: E-commerce can happen 24 hours a day, seven days a week. Consumers can buy at their convenience, and business owners can make sales while they sleep.
*   **Increased selection**: Many stores offer a wider array of products online than they could ever carry in their brick-and-mortar counterparts. And many stores that solely exist online offer consumers exclusive inventory that is unavailable elsewhere.
*   **Potentially lower start-up costs**: E-commerce companies may require a warehouse or manufacturing site, but they usually don't need a physical storefront. The cost to operate digitally is often less expensive than needing to pay rent, insurance, building maintenance, and property taxes.
*   **International sales**: As long as an e-commerce store can find a way to ship its products to its customers, it can sell to anyone in the world and isn't limited by physical geography.
*   **Opportunity to collect valuable data**: Willingly or unknowingly, consumers share a lot of information on their interests and shopping habits when they buy or even just browse online. [Site owners can monetize this data](https://www.investopedia.com/surveillance-pricing-11701007) in a number of ways, using it themselves and selling it to others.

### Disadvantages

There are also some drawbacks that come with e-commerce. Those can include:

*   **Limited customer service**: If you shop online for a computer, you cannot simply ask an employee to demonstrate a particular model's features in person. And although some websites let you chat online with a staff member, that is not a typical practice. A disadvantage for shoppers, this can also be a money-saver for retailers.
*   **Lack of instant gratification**: When you buy an item online, you must wait for it to be shipped to your home or office. However, [e-tailers](https://www.investopedia.com/terms/e/electronic-retailing-e-tailing.asp) like Amazon now make the waiting game a little bit less painful by offering same-day delivery as a premium option for select products.
*   **Inability to touch products**: Online images do not necessarily convey the whole story about an item, and e-commerce purchases can be disappointing when the items don't live up to the buyer's expectations. Case in point: an item of clothing may be made from shoddier fabric than its online image indicates.
*   **Dependence on technology**: If a website crashes or must be temporarily taken down for any reason, the business is effectively closed until things return to normal.
*   **Greater competition**: Although the low cost of starting an e-commerce business can be an advantage, it also means means competitors can just as easily enter the market.

Pros

*   Convenient for consumers, often with greater selection
    
*   Potentially low start-up costs for operators
    
*   Broadens reach of businesses to anywhere they can ship their products.
    
*   Opportunity to collect valuable consumer data
    

Cons

*   Limited customer service or assistance
    
*   Products can't be touched
    
*   Buyers must wait to receive purchases
    
*   Technological glitches can shut down the business
    
*   Low cost barriers to entry can also mean more competitors
    

## Types of E-commerce

E-commerce companies can operate using several different business models.

### Business-to-Consumer (B2C)

B2C e-commerce companies sell directly to the product's end-user instead of distributing goods through an intermediary such as another retailer.

This type of business model may be used to sell products (like your local sporting goods store's website) or services (such as a lawn care mobile app to reserve landscaping services). This is the most common [business model](https://www.investopedia.com/terms/b/businessmodel.asp) and the concept most people likely think about when they hear the term e-commerce.

### Business-to-Business (B2B)

Similar to B2C, an e-commerce business can sell goods to another company. B2B transactions often entail larger quantities, more detailed specifications, and longer lead times. The buyer can also arrange for recurring orders if the purchase is for ongoing manufacturing processes.

### Business-to-Government (B2G)

Some e-commerce businesses serve as government contractors, providing goods or services to government agencies and other entities. Often these arrangements require bidding on projects though an established procurement process and can involve large quantities of a given item.

### Consumer-to-Consumer (C2C)

Individuals can sell things to other individuals on their individual websites or through e-commerce platforms that facilitate the process. Examples of the latter include Craigslist, eBay, Etsy, and many others.

### Consumer-to-Business (C2B)

Some platforms allow individuals to more easily engage with companies and offer their services, especially related to short-term contracts, gigs, or freelance opportunities. Upwork is one example.

### Consumer-to-Government (C2G)

Although not an e-commerce relationship in the traditional sense, C2G is a way for individuals to interact with government. For example, uploading your federal tax return to the [Internal Revenue Service (IRS)](https://www.investopedia.com/terms/i/irs.asp) website can be considered an e-commerce transaction as it involves an exchange of information. Taxpayers can also pay what they owe or request a refund for the amount they may have overpaid.

## Types of E-commerce Revenue Models

Due to the unique nature of e-commerce, businesses have a variety of revenue models to choose from, based on how their goods are manufactured, sold, and shipped. Common examples include:

### Dropshipping

Often considered [one of the easier forms of e-commerce](https://www.investopedia.com/start-dropshipping-business-7972886), dropshipping allows a company to create a digital storefront, sell goods, and then rely on a supplier to take it from there. The e-commerce company collects payment from the buyer, after which it passes the order to the dropshipper. This supplier manages inventory, oversees the warehousing of goods, packages the orders, and delivers the product to the purchaser.

### White Labeling

In [white-label](https://www.investopedia.com/terms/w/white-label-product.asp) e-commerce, the seller doesn't manufacture the product but buys an existing product from the manufacturer or another supplier and repackages it under its own brand for resale to the ultimate consumer.

### Private Labeling

Similar to white labeling, private labeling involves selling a product made by another manufacturer. In private labeling however, the seller may have more control over the actual product, such as having it made to particular specifications. [Store brands](https://www.investopedia.com/terms/p/private-brand.asp) are an example of private labeling.  

### Wholesaling

Wholesalers serve the buyers of large numbers of a particular item or many smaller buyers of that item. A more capital-intensive approach to e-commerce, [wholesaling](https://www.investopedia.com/terms/w/wholesaling.asp) can entail maintaining and warehousing significant quantities of inventory.

### Subscription

E-commerce companies can also leverage repeat orders or loyal customers by implementing [subscription](https://www.investopedia.com/ask/answers/042715/how-do-subscription-business-models-work.asp) services. The consumer places an order once and receives their goods at a fixed cadence, such as every month. Common subscription e-commerce products include meal prep services, pet food, fashion boxes, and health and grooming products.

## Example of E-commerce

[Amazon](https://www.investopedia.com/amazon-earnings-4692665) is a behemoth in the e-commerce space. In fact, it is the world's largest online retailer and continues to grow. While its success has been unusually spectacular, its history is not unlike many other e-commerce businesses.

The company launched its business with an e-commerce-based model of online sales and product delivery. It was founded by Jeff Bezos in 1994 as an online bookstore and over the years has expanded to include everything from clothing to housewares, power tools to food and drinks, and electronics. Today it also makes a significant portion of its revenue from services to consumers, other businesses, and governments.

Company sales increased by 11% in 2024, totaling $638 billion, compared to $574.79 billion in 2023. Amazon's [operating income](https://www.investopedia.com/terms/o/operatingincome.asp) rose to $68.6 billion in 2024, up from $36.6 billion in 2023.  

## How Will I Use This in Real Life?

You don’t have to be the next [Jeff Bezos](https://www.investopedia.com/investing/how-jeff-bezos-got-be-worlds-richest-man/) to succeed in e-commerce. With today’s tools, you can spot a problem in your own life, create a solution, and turn it into a business. That’s exactly what Alex Zhou did as a Kansas State student. Frustrated by the lack of Asian groceries in his college town, he decided to build an online store to fill the gap. Starting with just his savings and a few hundred products, Zhou steadily grew his idea into Yami—a platform that now serves millions of customers and generates more than $100 million in annual sales.

The takeaway? E-commerce is accessible to anyone. Platforms like [Shopify](https://www.investopedia.com/how-shop-pay-makes-money-8639384), Etsy, and Amazon storefronts make it possible to test an idea with little upfront investment, making it easier than ever to turn small solutions into scalable, profitable ventures.

## How Do You Start an E-commerce Business?

First, figure out the kinds of products and services you want to sell and research the market, target audience, competition, and expected costs to see how viable that might be.

Next, come up with a name, [choose a business structure](https://www.investopedia.com/small-business-8611031), and get the necessary documentation (taxpayer numbers, licenses, and permits, if they apply).

Before you start selling, decide on a platform and design your website (or have someone do it for you).

Remember to keep everything simple at the beginning and make sure you use as many channels as you can to market your business so it can grow.

## What Is an E-commerce Website?

An e-commerce website is any site that allows you to buy and sell products and services online. Companies like Amazon and Alibaba are examples of huge e-commerce websites.

## What Is the Difference Between E-commerce and E-business?

E-commerce involves the purchase and sale of goods and services online, while e-business involves the entire process of running a company online.

## What Is an Example of an E-commerce Subscription Model?

Dollar Shave Club offers customers personal grooming, health, and beauty products on a subscription basis. Customers can begin with an inexpensive starter kit and receive new shaver blades and other supplies each month.

## The Bottom Line

E-commerce companies like Amazon, Alibaba, and eBay have changed the way the retail industry works, forcing major, traditional retailers to change the way they do business. At the same time, e-commerce has created new opportunities for small, new companies to find a niche. If starting an e-commerce site is something you're considering, make sure to do some market research and start with a small, narrow focus to give yourself room to pivot and grow.
