e-Invoicing in PANTHEON: how to issue and receive an e-invoice
What an e-invoice is, why a PDF sent by e-mail is not one, what to set up in PANTHEON and how incoming invoices can be received without retyping.
Short answer: an e-invoice is an invoice in a structured electronic form that the recipient’s system can process automatically. A PDF sent by e-mail is not an e-invoice. In PANTHEON you issue an invoice as before, and the program converts it into an e-invoice and sends it to an information intermediary, who delivers it to the recipient. Received e-invoices arrive the same way.
The issuing flow
- 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 fiscalises it, and the status returns to PANTHEON.
- Received e-invoices arrive the same way in PANTHEON.
What you need
- a current version of PANTHEON with an update contract, because Datalab delivers regulatory changes through new versions,
- a contract with an information intermediary (e.g. Moj-eRačun, FINA, PONDI or ZZI),
- code lists and documents set up for Fiscalization 2.0.
What changes from 2026 and what exactly to set up is described on the Fiscalization 2.0 page.
Incoming invoices without retyping
To receive incoming invoices we developed ArsURA, a web portal that:
- reads XML e-invoices directly, and PDF invoices with the help of artificial intelligence,
- has a person review every invoice before export,
- exports the result to Excel for import into PANTHEON,
- can automatically fetch invoices from Moj eRačun (MER).
Frequently asked questions
Is a PDF sent by e-mail an e-invoice? No. An e-invoice is a structured record, and a PDF is only an image of the invoice.
Do we need a contract with an intermediary? Yes. E-invoices are exchanged through an information intermediary, with whom you sign a contract. We help you choose one and connect it to PANTHEON.
Can incoming e-invoices be posted automatically? Received e-invoices arrive as structured data, so they can be processed and posted without retyping. The settings depend on your invoice approval process.
