If you use PayPal Website Payments Standard, when your customer checks out they will be directed to a page that allows them to log into their PayPal account or pay by credit card without having to sign up for a PayPal account.
Before you can use PayPal Website Payments Standard you need to sign up for a PayPal account.
Create a PayPal personal or business account at PayPal. We recommend you create a business account in order to keep your personal and business PayPal accounts separate. Opening a business account is preferable because it allows you to use a business name on the PayPal checkout pages and in theory allows you to keep your private name separate. Presenting a business name to customers will help build customer confidence. Additionally, a PayPal business account will allow you to configure a return URL which is required for proper configuration in the Smith Cart.
Go through the approval process to verify your account. This will require a bank account and correct contact information. You can contact PayPal customer service if you have questions here.
