E-invoicing in PANTHEON
An e-invoice (eRačun) is an invoice in a structured electronic format, exchanged between the sender's and recipient's systems, with no paper or PDF. In PANTHEON ERP you send and receive e-invoices directly from the program through an information intermediary (e-invoicing service provider). From 2026, this is mandatory for VAT-registered businesses in Croatia.
How e-invoicing works in PANTHEON
- You issue the invoice in PANTHEON as before.
- PANTHEON converts it into an e-invoice and sends it to the information intermediary.
- The intermediary delivers it to the recipient and fiscalizes it, and the status is returned to PANTHEON.
- Received e-invoices arrive in PANTHEON the same way.
Incoming invoices and ArsURA
For receiving incoming invoices we developed ArsURA, a web portal that reads XML e-invoices directly and PDF invoices with the help of artificial intelligence. A person reviews every invoice before export, and the result is an Excel file ready for import into PANTHEON. ArsURA can automatically fetch invoices from Moj eRačun (MER).
What you need
- a current version of PANTHEON with a maintenance agreement,
- a contract with an information intermediary (e.g. Moj-eRačun, FINA, PONDI or ZZI),
- registers and documents set up for Fiscalization 2.0.
Read more about the new obligations on the Fiscalization 2.0 page.
Frequently asked questions
Is a PDF sent by email an e-invoice?
No. An e-invoice is a structured record that the recipient's system can process automatically. A PDF is only an image of the invoice.
Do we need a contract with an information intermediary?
Yes. E-invoices are exchanged through an information intermediary, with whom you sign a contract. We will help you choose an intermediary and connect it to PANTHEON.
Can incoming e-invoices be posted automatically?
Received e-invoices arrive in PANTHEON as structured data, so they can be processed and posted without manual re-typing. The setup depends on your invoice approval process.
