Take Payments Easily with Jetpack’s Simple Payment Button
No matter what you use your Jetpack-powered site for, you want it to be successful — and profitable. But making money from your site has traditionally been a challenge if you don’t have the time to set up an online store. Well, now it’s easier to take payments for your products, services, or charity. Starting today, Jetpack Premium and Professional customers can add a Simple Payment Button to any post or page, and start taking payments with PayPal in just a few clicks.
To add a Simple Payment Button to your site, you’ll first need to add or edit a post or page in the WordPress.com Visual Editor. Click the drop-down arrow on the left, then choose Add Payment Button.
