Create payment buttons and shopping cart functionality in under an hour, and start accepting credit cards online with PayPal immediately. Over two million businesses trust PayPal to deliver easy, secure, affordable payment processing.

The toolkit includes the following objects:
The Buy Now object is a wizard that allows you to create a payment button for your product or service. You can place the payment button on a website, and immediately customers can pay you with any major credit card.

The Add to Cart and View Cart objects are wizards that allow you to add shopping cart functionality to your website. Customers can select items to purchase, and then check out and pay for purchases with a credit card. Advanced web developers can also add to and extend toolkit functionality by using PayPal payment APIs.

The Subscription object is a wizard that allows you to add recurring payments to your website. Use this object to set up an ongoing charge or payment plan for customers. You can also optionally set up a free or paid trial period, and also charge a setup fee to initiate the subscription.

Paypal setup is free, and there are no monthly fees. You pay only a small transaction fee when a purchase occurs, as low as 2.2% + $.30 per transaction (check PayPal site for current fee schedule). PayPal provides increased protection for online merchants via its built-in fraud prevention system. PayPal standard services include instant availability of funds, a scalable and proven payments platform, 24/7 customer service via email, and extended business hour telephone customer service.
