# Party schema

> The org/party schema, describing the legal entities and individuals involved in a transaction.

[`org/party`](https://docs.gobl.org/draft-0/org/party) represents a person or business entity involved in a business transaction. Parties appear embedded in billing documents as the `supplier` and `customer`, and can also be stored as documents in their own right.

Storing a party separately lets you register it with a tax authority or network, and lets Invopop link every document that references it.

## Registration

Party documents drive supplier and customer registration across most regimes and networks, including VERI\*FACTU, TicketBAI, KSeF, SDI and Peppol. A registration workflow sends the party to the authority or network and records the outcome on the entry. Each regime's supplier guide covers what its registration requires.

<Note>
  A party must be signed before documents that reference it will appear on its **Related** tab, and the lookup only runs in that direction. See the [related documents guide](/guides/related-docs).
