Számlázz.hu + Shopify integration
In short: MEGZO Integrator Vortex connects Számlázz.hu and Shopify: every Shopify order flows into Számlázz.hu as one idempotent record, and the Számlázz.hu invoice attaches back to the Shopify order automatically.
Keep Számlázz.hu as your invoicing system of record: MEGZO Integrator Vortex routes each Shopify order in and attaches the matching Számlázz.hu invoice back to the order.
What syncs between Számlázz.hu and Shopify
Why Számlázz.hu + Shopify on MEGZO IV
Dynamic field mapping

Never oversell
Stock pushed to Shopify with a buffer and reconciled, so a unit can't sell twice across channels.

Számlázz.hu + Shopify — FAQ
Does MEGZO IV sync stock between Számlázz.hu and Shopify in real time?
Stock flows on a 5-minute heartbeat and on demand, with push (webhook) wake-ups where Shopify supports them. It is pushed with an oversell buffer and continuously reconciled, so you never sell the same last unit twice.
Will a Shopify order create a duplicate in Számlázz.hu?
No. Order creation is idempotent — keyed on the channel order id with a unique constraint and an order-lock — so a retried or replayed order never creates a second record in Számlázz.hu.
Do I manage this from Shopify or from Számlázz.hu?
From neither — you manage Product, Price, Stock and Order syncing from your MEGZO IV vendor panel. Field mapping between Számlázz.hu and Shopify is dynamic; a non-developer can remap a field and it takes effect right away, with no code change.
Can MEGZO IV handle invoices for Shopify?
MEGZO IV fetches the invoice PDF that Számlázz.hu (or your invoicing service) already produced and attaches it to the Shopify order where supported. It never generates a fiscal/legal invoice and never submits to e-Factura/ANAF.
Is Számlázz.hu ↔ Shopify a good regional fit?
Számlázz.hu and Shopify share a regional footprint (HU), so this is a native fit.
