As mentioned earlier you have a number of options for taking credit card payments online. We have used Paypal as an example but you can also opt to use Google or another payment processing provider. But for now lets look at Paypal in a little more detail.
To get started with Paypal you need to sign up for a Paypal Business Account. Once you have signed up you will be presented with a number of options for taking payments. You can opt for a simple Order Now button if you only have one product or you can set up a Shopping Cart if you are marketing many products.
Either way Paypal will provide you with a number of tools to help you get started. For example they have a button generator that will generate the html that needs to go on your Sales Page and which connects to Paypal for payment processing.
