How we verify
Companies choose software and plan projects with this site. So every value has a source you can open and a day we last checked it – and where nothing is published, we say so instead of guessing.
Vendor data sheets
- 83
- vendors listed
- 44
- with a checked data sheet
- 803
- vendor sources cited in those data sheets
- 0
- paid placements, reviews or star ratings
A data sheet records what the vendor states publicly: product pages, documentation, price lists, certificates and audit reports. Each value carries its source and the date we read it. If a vendor publishes nothing on a point, the data sheet says “no public information” – the finder scores it like a missing point, but it never removes a vendor and the match strip shows it differently from a “no”. Only published data showing that a vendor does not offer the required deployment or hosting region removes it from a ranking.
Vendors listed without a data sheet are shown as “not yet assessed”. Vendors can send corrections with a source; we check them before changing anything.

Which source counts
- The law itself
Official journals and consolidated legislation: Moniteur belge, Dziennik Ustaw, Légifrance, Bundesgesetzblatt, Gazzetta Ufficiale, BOE, Monitorul Oficial, Slov-Lex, EUR-Lex.
- The authority
Tax authorities, finance ministries and national e-invoicing portals: their pages, FAQs, technical specifications and official press releases.
- EU institutions
The Commission's eInvoicing country factsheets and ViDA pages. They often lag national law by months, so a national source wins if they disagree.
- Everything else
Peppol bodies, advisers, vendors and press only help us find the official source. They never confirm a date on their own.
Our labels
Confirmed means the date is in adopted law or an official publication of the authority, or follows unambiguously from it (we then show the calculation).
Not officially confirmed means the date comes from an announcement, a draft law, a consultation or secondary reports. We show it, because you need to plan, but we say what is missing.
Month or year only: when the law names only a month or a year, we show only that, never an invented day.
How often we check
Every country profile is re-checked at least once a month. Each page shows when it was last verified and when the next check is due. We read the sources in their original language and verify each date, threshold and amount in the text itself, not in a summary.
When something changes
We update the value and record the change with the date, the old and new value and the source. The entries appear on What changed, in the RSS feed and in the calendar files. E-mail alerts are being set up; they will be reviewed by a person before they go out.
Limits
We describe obligations; we do not decide whether your entity falls into a group or phase. Thresholds, establishment and invoice types decide that, and the readiness check shows each step with the group it applies to. The site is information, not legal or tax advice – see the disclaimer.
Independence
No provider can pay for a date, a wording or a position. We do not use affiliate links. If providers pay for introductions in future, we will say so on For providers.
