It also reassures your buyer that you use a secure and reliable payment processor. * **Placement** — Keep the PayPal payment button visible and close to the item to be purchased. Display the button below or to the right of the item. * **Eliminate unnecessary content** — Do not add potentially confusing text or images around the payment button, including any unnecessary legal text or warning. * **Use the View Cart button** — If you are integrating the Add to Cart button, display the View Cart button on every page so that buyers can easily view the contents of their shopping cart. ## Checkout flow [#checkout-flow] When buyers click the PayPal payment button, they are directed to PayPal and prompted to either log in to their PayPal account or enter a credit card. If the buyer has a PayPal account, he or she can select their billing and shipping information. When the transaction is complete, the buyer is returned to your website.
