Third-Party Transaction. What is a 'Third-Party Transaction'. A third-party transaction is a business deal involving a buyer, a seller and a third party. The third party's involvement varies with the type of business transaction. For example, an online payment portal, such as PayPal, acts as a third party in a retail transaction.
In the computer world, a third party may refer to either a hardware manufacturer or a software developer. It is a label given to companies that produce hardware or software for another company's product. Third party hardware refers to components that are developed by companies besides the original computer manufacturer. For example, a person may buy a Dell computer and then upgrade it using third party components, such as an Nvidia video card and a Seagate hard drive.
