KISS Principle So Important For E-commerce Websites
There are many technical requirements to properly answer the question of how can I sell online? - you’ll need a good e-commerce template for a start and very solid, robust hosting, as well as an account with one of the payment providers like PayPal or Google Checkout - or even a merchant account issued to you from an acquiring bank.
Even after you’ve met all the technical requirements, there is still one more important factor to consider - to make the buying process simple on your website. Shoppers shouldn’t need to register when buying items for example. They should know immediately how they can pay for their items (make this clear throughout your site).
Be on your customer’s side and make it easy for them to make their purchase.
