Think of an e-commerce website as a storefront for products and/or
services that you want to sell online. Your job is to convert your
website visitor into actual buyers. You need to have plenty of
appealing content and products on your site to attract search engines
as well as to inform prospective clients.
Here are the main parts of an e-commerce site:
The online product catalog is the main place to store and manage the information about products or collections of products.
The shopping cart is a familiar interface buyers use to
select products they want to buy. The shopping cart just holds
information about the products that your customer is about to purchase
and assists them with the checkout process.
The checkout system collects necessary payment information
from the buyer, including shipping & billing addresses and credit
card information or details of other payment mechanisms. It may also be
configured to present shipping rates, taxes, coupons, or calculate
other changes to arrive at the final price.
The payment gateway is a secure service that transfers
payment and credit card information from your website to a merchant
account provided by a bank or financial institution that handles online
transactions. The gateway mechanism also handles any feedback from the
bank, such as when a buyer has insufficient funds or is using an
invalid credit card. The payment gateway is also tasked with validating
that the credit card actually belongs to the user.
The merchant account is a special bank account that allows
your website to accept online payments by debit or credit cards.
Merchant account banks charge variable fees per transaction and
transaction types, partially based on the bank’s assumption of risk to
collect money on your behalf.
Finally, fulfillment is when the order is processed through the e-commerce website and results in a completed order that is shipped out.
