NFCom (Nota Fiscal de Comunicação) is used for telecommunication services like internet, phone, and TV subscriptions.

Why should I manifest NF-e?

Manifestation confirms that your company acknowledges receiving the goods. Events include Ciência da Operação (210750), Confirmação (210760), and others.

Can I list all NFS-e received by my company?

Yes, use the `list_received_nfse` tool to see all service invoices where your company is the taker (tomador).

Can I emit an NFC-e offline?

Yes, NFC-e allows issuance in offline contingency. Your AI agent can prepare and log the NFC-e locally until the connection is restored, then it will sync via the API.
