The most common way of paying for products on-line is via credit card. To make sure you do not miss out on sales you need to ensure you have a merchant account with your bank and a payment gateway such as Worldpay or Secpay. Your web design company and your bank will help you set this up.
Credit card processing is carried out away from your site on a secure server and you will not have access to any credit card details. This guarantees security for both you and the purchaser.
When payment has been accepted, you will be notified that the transaction is ready for processing and you can send the goods to your customer. The customer’s payment is then deposited into your business account by the payment processing company.
