E-commerce is the ability to conduct sales transactions online. This includes selling items on your website.

The benefits of e-commerce is that you are opening new revenue streams. Instead of having a website that only provides information you can have a website that provides information and also offers consumers a new way to purchase from you.

The downside are the security issues with e-commerce. Many e-commerce enabled sites make sales by accepting credit card information online. This credit card information needs to be protected from hackers and other attackers. Other common payment methods used in e-commerce transactions include e-checks and paypal payments.

If you would like to add an e-commerce capability to your website there are many solutions available to you. You can outsource it to a third party website or you can manage the e-commerce on your site. If you manage it on your site you can buy an off-the-shelf software package or design your own solution.

in my own perspective, e-commerce involves buying and selling purchase online as well as transferring funds, something about finance and money but the medium is the internet

what is the process to have the E-commerce on our website?

We must not forget that e-commerce is a concept, and to follow the concept means you have understood well what encompasses it; first is that you should have a product to sell, and another thing you would have to consider is to review what is inclusive of online marketing. There would be no e-commerce without the presence of any client. So thru online marketing, we search for a client. In that process alone, there are a lot of things to do. But just so it is clear to everyone, e-commerce entails you having a store online and that could be a web site and blogs connected to it.

Is there any website that has the facility of E-commerce?
