So verifizieren wir jedes Unternehmen auf PVFirms.
PVFirms ist redaktionell, nicht käuflich. Jeder Eintrag – Gelistet, Verifiziert oder Premium-Partner – durchläuft dieselben öffentlich dokumentierten Prüfungen. Kein Unternehmen kann eine höhere Stufe kaufen. Diese Seite ist das Regelwerk.
Vertrauen, schrittweise verdient
Jedes Unternehmen beginnt bei Gelistet. Die Stufen bauen aufeinander auf – Verifiziert übernimmt alle Prüfungen von Gelistet, Premium-Partner übernimmt Verifiziert. Unternehmen steigen erst auf, wenn sie die nächsten öffentlichen Kriterien erfüllen.

Von der Einreichung bis zum Abzeichen
Submission & intake
Company submits via the Add Your Company form, or claims an auto-generated profile. We log company name, registered address and self-declared category.
Public registry sweep
Cross-check across VIES (EU VAT), national commercial registers (Handelsregister, KvK, Mercantile Register, etc.) and OpenCorporates. Rejected if registration is dissolved or inactive.
Document & identity review
We request certificate of incorporation, current insurance certificate, officer ID and recent invoices to confirm trading activity. Documents are stored encrypted, never published.
Reference & review check
Declared customers are contacted. Independent search for negative press, regulatory actions and review patterns. Notes are attached to the company file.
Inspection (Premium)
For the Premium Partner tier: a closer editorial inspection of the company's operations, certifications and staff.
Tier assignment & publication
The verification outcome is published on the company profile with the badge. Companies can appeal a tier decision; appeals are reviewed independently.
