It is important when offering products online that you use a reliable shopping cart system. The Zen Cart open source (free) shopping cart system integrates PayPal into it’s payment modules.

If you wish to pay the fee to have Paypal’s Web Payments Pro, you can have your zencart shopping cart process credit card transactions “behind the scenes” and no one ever knows you are using Paypal as the processor. If you use this method, you will need an SSL Certificate for your website to follow PCI Compliance Regulations.

PayPal enables your customers to purchase your products via any major credit card or withdrawal from their checking account in the form of an E-check. PayPal now offers the option of either setting up an account with them in order to record account information OR not setting up an account and entering credit card information each time a purchase is made. Using Paypal in this manner does not require you to purchase an SSL Certificate because all credit card data is entered on Paypal’s secure server.

When choosing to use PayPal for your shopping cart, you must take into consideration whether or not you wish to accept personal checks or money orders mailed to you for a product. If so, the Zen Cart Ecommerce shopping cart allow you that flexibility as well.

PayPal charges a percentage of the sale as a fee for their service. Unlike other merchant accounts that charge monthly statement fees, fees per sale, percentage of gross sale and monthly maintenance fees, PayPal only charges the one fee. This can save a business owner tons of money over the course of a year.
