E-Commerce websites are online portals that facilitate online transactions of goods and services through means of the transfer of information and funds over the Internet. In the early days, e-commerce was done partially through emails and phone calls.
Here are the steps you follow on an e-commerce website ~
A customer chooses one of your products, a sweater, and s/he adds it to the cart. All the information is saved in the database.
The order manager queries your database to find out if the sweater of that exact color and size is actually in stock.
If it’s not in stock, the stock database may order more items from a manufacturer. If it is in stock, the stock database confirms the sweater is available.
A merchant system accepts the payment.
The bank confirms there’s enough money on your customer’s credit or debit card.
When the transaction is successfully processed, the web server is notified. Then the customer gets a message that the transaction is complete.
The order manager requests to dispatch the order from the warehouse to the customer. When it’s dispatched, the customer gets an email.
The order is delivered to the customer.
