When an entity accepts credit card orders on the behalf of another company, namely usually a bank or other merchant account establishment, this entity is called a third-party credit card processor. This is often the way e-commerce merchants choose to go to set things up so that they can accept credit cards, because they do not need to go through the process of setting up an actual merchant account this way. However, the drawback to this method is that the merchant has to be able to sell enough goods or services to cover the extra fees charged by the third party. This method works by having the credit card process go through the third party instead of directly through the merchant.
The third party has a merchant account with a particular entity, such as a bank. The online merchant who wishes to establish credit card processing privileges uses the third party’s merchant account privileges to accept orders for their own company.
This is generally a very expensive way to go for merchants to accept credit cards, but in some cases is also the best way, since it’s very easy to set up and merchants can be in business very quickly. It’s also a good way to go for online merchants who may not have the credit rating, business history, or other requirements necessary to set up a merchant account directly, themselves.
