Do I have to convert invoices for PROLUC into another format?

No. PROLUC imports invoices in the Peppol BIS 3.0 format directly; from the portal you download the original XML (a ZIP with the prijate and odoslane folders) and save them in the folder PROLUC has set for the import of Peppol invoices.

Is the procedure verified by the vendor?

INFOPRO confirmed on 6 October 2026 that the import of Peppol invoices is ready in PROLUC and approved our procedure. Joint testing on real documents (XML and the printed PDF report) is under way; we will add the result to this page and to the guide.

What if my version of PROLUC has no Peppol invoice import?

Use the PROLUC export from the portal (proluc.csv, document headers in the Windows-1250 encoding) and the Import from other software add-on of the PROLFA module; INFOPRO supplies the conversion table for this source. INFOPRO can tell you whether the Peppol invoice import is available in your version.

Can I also send e-invoices from PROLUC?

Sending goes through the portal: the form, a UBL XML file or an XLSX following the template, also in bulk. Loading the export of issued invoices straight from PROLUC is in preparation; if you send us a sample export, we will add it.

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.
