We provide features and services for the pre-checkout and post-checkout phases of an online purchase; while PayPal provides some very basic cart and purchase buttons and order-reporting features, ours are much more flexible, sophisticated, full-featured and just plain easier to use. In a manner of speaking, we provide the "bread" in an e-commerce "sandwich" where PayPal (or other payment processor) just provides the "meat" of checkout itself, where payment funds are exchanged; while PayPal does also offer some basic white bread, we give you thick-sliced artisan-crafted multigrain. :^)
For the pre-checkout shopping stage of purchase, we provide cart button codes that add a sophisticated shopping cart interface to your site that appears as an overlay "inside" your page (no unsettling popups nor change of domain or look and feel), with easy point'n'click product configuration and management via our Seller Admin interface (no more manually configuring button codes by hand like PayPal's standard buttons), which also makes our button codes tamper-proof (e.g., crooked buyers couldn't modify a copy of your E-junkie button code to alter the product's price). Our cart supports flexible and sophisticated discounts, sales tax and shipping calculation, and even buyer-editable pricing with minimum and suggested prices.
Post-checkout, we save the order details to a transaction log and send them to you in a Sale Notification email, send the buyer a thank-you email message, and generate a thank-you page where we would automatically present download links for any downloads they'd purchased, and we can forward the order data to custom/3rd-party services for additional post-processing needs. The download links we issue are unique to each buyer and would expire after the number of attempts or hours you specify, so they'd soon become useless even if a buyer tried to share their link with others. For eBook sellers, we can stamp the buyer's name, email address and unique transaction ID one very page of the PDF file they download, a strong deterrent to file sharing.
