Is there a Verteco plugin for HELIOS?

We do not yet have a ready-made plugin for HELIOS, and we do not claim otherwise. File exchange works: received invoices from the portal as ISDOC into HELIOS, issued invoices from HELIOS as ISDOC or UBL for sending through the portal. A direct connection is delivered as a managed custom connection.

According to the vendor, HELIOS has its own access point to the Peppol network. Why bother with Verteco?

It is your choice. According to the Slovensko.Digital overview of September 2026, HELIOS supports ISDOC and UBL and the vendor lists its own access point. With us you have receiving, the portal, exports, the report to the Financial Administration and the API right away and independently of the state of your HELIOS installation (free until 31 December 2026). The rule of the Financial Administration applies: only one provider can receive for a given tax ID, while you can send through several, so both paths can be combined.

What do I need in HELIOS?

The ISDOC interface (export and import of documents) or an invoice export to UBL; check the availability of these functions in your installation and version (iNuvio, Nephrite) with your implementer or in the Asseco Solutions documentation. The exact menu paths differ between versions, so we do not quote them from memory.

How do I get a received e-invoice into HELIOS?

In the portal you open Exports, choose the company and period and download ISDOC (.zip): every invoice is a separate .isdoc file in the prijate folder, which HELIOS loads with its ISDOC import. The original UBL XML is always available too.

How much does a managed custom connection cost?

A one-off fee, priced by scope (formats, number of companies, way of connecting). Write to peppol@verteco.digital or call +421 944 488 269 (Mgr. Miriama Mrkávková) and we will propose the exact procedure and price.

How much does it cost?

The service costs from €2/month excl. VAT per company ID (IČO) that sends or has the Data archive switched on (the default for new companies): receiving, sending and the archive of originals in the EU. A company with the archive off that only receives pays nothing (up to 1,000 invoices a month). During the voluntary period before the mandate of 1 January 2027 everything is free of charge.
