Which programs read ISDOC and where can I upload it from?

The ISDOC 6.0.2 standard is read by most Slovak and Czech programs (Money, OBERON, HELIOS, ABRA); for POHODA we recommend the native dataPack export, which is in the portal separately. For sending we accept invoices in the ISDOC 6 format from Money S4/S5, POHODA, iDoklad, Fakturoid and other programs, and the ZIP from our ISDOC export.

What does the portal refuse when importing ISDOC?

An advance invoice (DocumentType 4), which is not a tax document, a document in a foreign currency, a VAT rate other than 23, 19, 5 and 0 %, reverse charge, a document with a deducted paid advance, a document of another company (by company ID or VAT ID), a document without lines or without totals and a file whose totals do not match the lines. You see the reason for every refusal.

How is a credit note handled in the ISDOC export?

A credit note goes as DocumentType 2. If the original e-invoice from the Peppol network carries a reference to the original invoice, the export puts it in OriginalDocumentReferences together with the date; without it the reference is omitted, the program asks for the original document and nothing is invented.

Is ISDOC the original of the invoice?

No, ISDOC is a conversion for your accounting program. The signed originals, exactly as they passed through the Peppol network, are downloaded in Exports as Original XML (.zip); you also receive every received invoice by e-mail as a PDF with the original XML.

Why is there an ISDOC tile and a Money S4 / S5 tile in Bulk send?

ISDOC is a standard, not a program. The ISDOC tile is for any program that exports ISDOC, and for the ZIP from our export; the Money S4 / S5 tile is for users who look for their program. Both use the same import.

How much does it cost?

The connection is free. The service costs from €2/month excl. VAT per company ID (IČO) that sends or has the Data archive switched on; receiving with the archive off is free (up to 1,000 invoices a month). During the voluntary period before the mandate of 1 January 2027 everything is free of charge.

E-invoices and the ISDOC 6.0.2 format

Export + import

ISDOC is a standard for exchanging invoices that most Slovak and Czech accounting programs read (Money, OBERON, HELIOS, ABRA and others). The Verteco portal converts every received and sent e-invoice from the Peppol network into ISDOC 6.0.2, one .isdoc file per document, and the other way round you upload invoices in the ISDOC format from your program for sending through Peppol in Bulk send. For POHODA we recommend the native dataPack export.

The path that works today

1Activate your account and company on peppol.verteco.digital (provider selection on the Financial Administration portal via slovensko.sk). From then on receiving e-invoices through Peppol works without changing your program; you get every received invoice by e-mail as a PDF with the original XML.
2In the portal open Exports (/dashboard/exports), choose the company, direction and period and in the Universal formats section download ISDOC (.zip). The ZIP holds the folders prijate/ and odoslane/ with <invoice number>.isdoc files, one file per document.
3Import the .isdoc files into your accounting program with its ISDOC import function. A credit note carries the reference to the original invoice when the original e-invoice contained it; without it the reference is omitted and the program asks for the original document.
4Upload issued invoices in the ISDOC 6 format (.isdoc or .xml files, or the whole ZIP from the export) in the portal under Send e-invoice → Bulk send → ISDOC, several files at once if you like. The portal recalculates the amounts as for a manually issued invoice and does not send the invoice if they disagree with the file; received invoices (the prijate folder) are skipped.

What you have right away

✓Export of received and sent invoices and credit notes to ISDOC 6.0.2 (UTF-8, one .isdoc file per document, folders prijate/ and odoslane/)
✓A stable document UUID: programs that remove duplicates by UUID recognise a repeated export as the same document
✓The tax ID in the TIN tax scheme and the VAT ID in the VAT scheme; a credit note as DocumentType 2 with the reference to the original invoice when the original carries it
✓Import of invoices in the ISDOC 6 format from Money S4/S5, POHODA, iDoklad, Fakturoid and other programs, and of the ZIP from our export; several files at once
✓Amounts are never adjusted on import: if the totals in the file do not match the lines, the invoice is not sent and you see the reason
✓Receiving e-invoices works right away and independently of the program (Peppol Box in the portal); delivery receipts (MLS) and the status of every invoice in the Verteco portal
