{{Wiktionary|third party}}

In [commerce](/source/commerce), a '''third-party source''' means a supplier (or [service provider](/source/service_provider)) who is not directly controlled by either the [seller](/source/sales) (first party) nor the [customer](/source/customer)/[buyer](/source/procurement) (second party) in a business [transaction](/source/Financial_transaction).<ref>{{Cite web|url=http://www.sp.se/EN/PRESS/GLOSSARY/Sidor/default.aspx|title=Glossary|website=Rise Research Institutes of Sweden|archive-url=https://web.archive.org/web/20090213030328/http://www.sp.se/EN/PRESS/GLOSSARY/Sidor/default.aspx|archive-date=2009-02-13|url-status=live|access-date=2018-07-28}}</ref> The third party is considered independent from the other two, even if hired by them, because not all control is vested in that connection. There can be multiple third-party sources with respect to a given transaction, between the first and second parties. A second-party source would be under direct control of the second party in the transaction.<ref name="Yale">

In [e-commerce](/source/e-commerce), '''3rd party''' ('''3P''') '''source''' refers to a seller who publishes products on a marketplace, without this marketplace to own or physically carry those products. When an order comes in, a 3P seller has the item on hand and fulfills it. An example of 3P sellers are merchants participating in [Amazon](/source/Amazon_(company))'s FBM program.<ref>{{Cite web|url=https://www.geekseller.com/blog/online-sales-and-its-sellers-1p-2p-3p/|title=Online Sales and Its Sellers (1P, 2P, 3P)|website=GeekSeller|access-date=2019-06-01|date=2017-09-05}}</ref>
