Forditott ÁFA (Hungarian reverse-charge VAT)

Related service Custom software · everything else

DEFINITION

EU intra-community B2B VAT rule. The seller does NOT charge VAT - the buyer (a B2B customer in another EU member state) self-accounts for it in their own country. Works for e-commerce when the buyer provides a valid EU VAT number (verified in VIES). Mandatory invoice text: 'Reverse charge'. If the shop doesn't verify the VAT number, the buyer can demand a refund of the 27% VAT - risky. Typical invoicing systems (Számlázz.hu, Billingo, NAV-compatible) handle this automatically.

RELATED TERMS06
  • Docker→

    We package an app with its dependencies into an image, which runs as a container - identical on your laptop and in production. "Works on my machine" stops being an excuse.

  • CI/CD→

    Continuous Integration / Delivery: every commit is automatically built, tested and (optionally) deployed. This pipeline lets us ship safely many times a day, without manual mistakes.

  • Blue-Green Deployment→

    We run two identical environments: blue is live, green is the new version. Once green is verified we flip traffic to it; on trouble we flip back instantly. Zero-downtime releases with instant rollback.

  • Horizontal Scaling→

    We add more machines/instances (scale out) instead of one bigger box (vertical, scale up). For stateless services this wins: cheaper, more elastic, no ceiling. State goes to a separate store.

  • Load Balancer→

    Distributes incoming traffic across multiple instances - the front door that gives you redundancy and smooth scaling. Health checks remove dead instances, so one failure stays invisible to users.

  • Distributed Tracing→

    We follow one request across every service using a trace ID (e.g. OpenTelemetry). In a microservices system this is how we pinpoint which service slowed down or failed - no guessing.
