# Delete counterparty

Delete a counterparty.

Permanently deletes the counterparty. System counterparties (the tenant catch-all records) cannot be deleted. Issued invoices, transactions, and catalog payment methods are kept: this counterparty link is cleared, so they become unlinked rather than deleted or moved to Default System. Shared payment methods stay linked to their other counterparties. Existing matches between invoices and transactions are unchanged.
