What does "connected subject" mean?

A subject whose tax number has a valid SML record in the Peppol network and an access point published in the SMP that receives e-invoices on its behalf. This is exactly what a sender checks before delivery; without the record an invoice cannot be delivered via Peppol.

Why is your number higher than the count in the Peppol Directory?

Publishing in the Peppol Directory is optional for providers and many do not enable it. Our sweep goes straight through the SML and SMP, the mechanism the network actually uses for delivery, so it also sees subjects that are absent from the Directory.

How often are the statistics updated?

The full sweep of every tax number runs each morning; newly connected subjects are added during the day. Every figure carries the measurement time and the date of the Financial Administration list it is based on.

May I use the data in my own article or analysis?

Yes. The data is published under Creative Commons BY 4.0: use it freely, name the source "Verteco Peppol Observatory, peppol.verteco.digital/statistiky" and the date. The Cite button prepares the exact wording.

Methodology

Every day we check all roughly 315,000 Slovak tax numbers from the public Financial Administration list against the Peppol SML (the same DNS lookup every access point performs before delivery).
A subject’s provider is determined from the certificate of the access point registered in the SMP, not from marketing lists.
The full sweep runs every morning; intra-day updates pick up subjects connected during the day. The date of the FS list is stated with every measurement.
