What is ecommerce?
The buying, selling or trading of products and services over the internet is called ecommerce (the ‘e’ stands for ‘electronic’). Generally, the term also encompasses the transfer of money – funds – to complete such buying, selling, or trading transactions. In an ecommerce context, both sellers as well as buyers can be individuals, small to medium-sized businesses, or even large businesses and governments or governmental organisations.
Some sellers might opt to sell only online exclusively, whereas others could have both physical stores – also called ‘brick-and-mortar’ stores – in combination with an online presence, either on their own website or through Amazon or other such websites.
Ecommerce trends and statistics
The field of ecommerce looks set for continued growth. By 2025, online sales are expected to make up nearly a quarter of total global retail sales. More than 2 billion people bought products online in 2021, resulting in nearly $5 trillion in retail ecommerce sales. This number is expected to grow to $6.54 trillion in 2022, hitting $7.4 trillion by 2025.

- Lower overheads and operating costs
- Engage with customers directly
- Worldwide business coverage
Ecommerce businesses can operate without the need for physical stores, warehouses, or a large number of employees. Setting up and maintaining a website can be less expensive than starting a physical store. Several online tools might make it easy for you to set up a website – or you could launch your business on websites like Amazon, potentially removing the need to have a website of your own.
Ecommerce brands could build relationships with their target audience directly while catering to their wants and needs, including through special offers and personalised product recommendations.
The global reach of electronic commerce provides benefits to both customers as well as businesses. Customers do not have to physically travel the world to buy products from different countries. They can also access a wider range of products thanks to the internet. Similarly, businesses too might reach customers all over the world, diversifying their reach.
Ecommerce challenges

Although there may be workarounds available, these challenges can cost you time and money. You could consider building your own store on Amazon, alternatively, to gain the benefits of working with an established, trusted technical infrastructure.
With an increasing number of interactions being conducted online, customers are concerned about how their information is stored and shared. A detailed and clear privacy policy can help build trust and reassure your customers that you will safeguard their personally identifiable information. You might also need to ensure that you use a highly secure payment processing service like Amazon Pay to help avoid putting customer data at risk.
Because of ecommerce, customers now have abundant options to browse, compare and buy products and services with ease from anywhere in the world. It may be difficult for small and medium-sized businesses to ensure proper delivery of products to multiple countries or continents and guarantee safe payment options. Services like Fulfilment by Amazon can handle the process of picking, packing and shipping your products to customers in multiple countries with ease.

- Own store vs existing website
- Scaling up internally vs outsourcing services to external vendors
