====== Invoices to natural persons registered in AMS ======

Although invoices to citizens are normally fiscalised under the **//F1//** protocol, there are exceptional cases where a natural person is registered in **AMS**((Address book of metadata services)). In such cases the outgoing invoice is sent to that customer under the **//F2.0//** fiscalisation rules.

**System prerequisites**\\ For the automation to work correctly, the partner data (natural person) must:
  - Contain the person's **OIB**.
  - Have the //**{Registered in AMS}**// field ticked.

If the system finds when sending the invoice that the customer is not registered in AMS after all, it proceeds as described in [[brix:en:invoices:ams-none]].

<note important>
Only **system administrators** may change or correct the //**{Registered in AMS}**// field.
