    FIRS/NRS-compliant e-invoicing — generates Invoice Reference Numbers (IRN)
    and QR codes and submits invoices to the tax authority via an accredited
    Access Point Provider connection. Earnipay is described as an accredited NRS
    and NITDA systems integrator.
notes: >-
  Regulatory conformance (Nigeria Revenue Service e-invoicing / NITDA) is a
  domain standard the platform implements, not a published security-compliance
  certification program (SOC 2 / ISO 27001 / PCI). No such security
  certifications were found, so no Compliance pointer is emitted.
