Losses on small-contractor prepayments cluster where no one verified the registry entry. The check closes the common scenarios — wrong NIP, dead registration, mismatched trade — for less than the cost of a lunch.
Personal, unlimited liability means the verified identity is also your enforcement path if things go wrong.
Structured record plus branded PDF by email within minutes; one-time payment from €9.99.
The NIP and name on the invoice against the registry entry, the entry's status (active, suspended, deregistered), and whether the activity codes fit the offered services.
Invoices bearing someone else's NIP, or businesses deregistered months ago still collecting deposits — both caught instantly by the lookup.
Yes — the delivered PDF timestamps what the registry showed when you checked, useful for disputes and compliance.
