Paid listings are not really an e-commerce solution per se, but do allow individuals/businesses the ability to sell goods via a marketplace such as Ebay, Amazon, or comparison shopping engines. Ebay and Amazon offer merchants paid listings in return for fees and a percentage of the transaction which tends to be a 10%- 20% commission or referral fee. Shopping engines charge a pay per click model as advertising fees.
For more sophisticated sellers, paid listings is just another sales channel and not an ecommerce solution but need to be addressed. Most full service e-commerce platforms will allow you to feed your products into these marketplaces.
Summary - Not really an e-commerce solution, but important enough to mention.
