The eInvoices business solution covers issuing quotes and invoices, sending invoices for fiscalisation under the F1 or F2.0 protocol, receiving and approving incoming eInvoices, and posting all of these documents the moment they are closed. When an invoice is closed, Brix selects the protocol, sends the invoice to the information intermediary, tracks the delivery status and reports the payment through eReporting.

Fiscalisation 2.0 is not merely a technical upgrade of the existing system; it is a comprehensive digital transformation of business in the Republic of Croatia.

It is a legally prescribed system in which every issued invoice — whether for transactions between businesses (B2B) or sales to consumers (B2C) — is automatically reported to the Tax Administration in real time.

All invoices issued to consumers (B2C) are also subject to mandatory fiscalisation, regardless of the payment method. This includes bank transfers as well as digital services such as Stripe, PayPal, Revolut, KEKS Pay, Apple Pay and Google Pay.

The Fiscalisation 2.0 system covers:

• Mandatory issuing of fiscalised eInvoices — every invoice line must be correctly classified according to the current Classification of Products by Activity (KPD 2025).
• Integrated e-archive — all eInvoices are stored digitally and remain permanently available in electronic form.
• Connected online bookkeeping — enabled within the VAT system for real-time monitoring and reporting.

• Documents | [ Quotes ]
  Quote to a customer; the INVOICE button creates a draft invoice from the quote, the DELIVERY NOTE button a delivery note, in the same department.
• Documents | [ Invoices ]
  Issuing all types of outgoing invoices, cancellations, credit notes and advance payments; sending for fiscalisation and eReporting of payments.
• Documents | [ FA Invoices ]
  Sale of fixed assets with automatic depreciation up to the date of sale.
• Documents | [ Bills ]
  Receiving eInvoices from the intermediary and approval through the statuses Received → Accepted → Closed; the same actions are available in the [ Accounts Payable ] form.

The rules deciding whether an invoice goes to F1 or F2.0 fiscalisation are described in Sending invoices to F1 or F2.0 fiscalisation. Brix supports two information intermediaries — mer and eposlovanje; the user contracts the service with the intermediary, and support enters the credentials into Brix.

• eReporting of invoice payments
  eInvoice status in the invoice list, F1/F2 marks and real-time payment reporting.
• Invoices to natural persons registered in AMS
  Natural persons registered in AMS receive eInvoices; when the customer is not registered in AMS, the Tax Administration is notified automatically.
• paper_invoices

• eura

When an outgoing invoice is closed, Brix immediately posts the receivable, the VAT liability and the revenue; the entries are visible in the invoice's ~ JOURNAL ENTRY ~ tab. A closed bill is posted the same way. Invoices enter the VAT return and the balance sheet by delivery date, and closed VAT periods are protected by the mechanism described in vat_period.
