[Counterparts](https://docs.monite.com/common/counterparts/index) of the `organization` type can have additional contacts defined. Contacts are useful if you need to use different contact information for the same counterpart in different [invoices](https://docs.monite.com/accounts-receivable/invoices/index).
The first contact you add to a counterpart becomes its default contact. The default contact, if it exists, is automatically selected when you create invoices and quotes for this counterpart, but the contact information can also be changed later on the document level. To select a different contact as the default one, use `POST /counterparts/{counterpart_id}/contacts/{contact_id}/make_default`.
