  - before: Before paying: check the seller of an invoice in the public registers (ANAF for Romanian CUIs, VIES for EU VAT numbers): registered name, whether it matches the invoice, VAT registration and whether the company is active. Returns warnings to act on.
  - after: Before paying: check the seller of an invoice in the public registers (ANAF for Romanian CUIs, VIES for EU VAT numbers): registered name, whether it matches the invoice, VAT registration, whether the company is active and (ANAF) whether it is in the RO e-Factura register.
