An online trading company is a trading company that operates primarily through the internet and its e-commerce tools. Similar to any regular retail company, online retailers specialize in buying goods from manufacturers and reselling them to consumers or other retailers. However, the online nature of this business makes it different and comes with specific benefits and limitations. Selling goods online offers enormous opportunities and advantages, since you can trade worldwide and save on organizational and administrative costs such as wages, office rent and others.
The main difference is that a 100% online trading company (with no physical stores whatsoever, just headquarters and warehousing facilities) requires virtual rather than physical infrastructure. An offline trading company needs offices, shops, warehouses and a logistics network that connects suppliers, offices and points of sale; An online trading company needs offices, storage space, powerful servers and websites, and a flexible logistics system that allows it to serve customers in many locations.
As you can see, online trading companies require less physical infrastructure, but they also need to be much more flexible to serve their customers. While a website is a useful addition for a regular trading company, for an online trading company it is an indispensable tool without which the company cannot function – hence the high demands on the website and host server's capabilities.
