Számlázz.hu + Squarespace Commerce — FAQ
Does MEGZO IV sync stock between Számlázz.hu and Squarespace Commerce in real time?
Stock flows on a 5-minute heartbeat and on demand, with push (webhook) wake-ups where Squarespace Commerce supports them. It is pushed with an oversell buffer and continuously reconciled, so you never sell the same last unit twice.
Will a Squarespace Commerce 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 Squarespace Commerce 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 Squarespace Commerce 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 Squarespace Commerce?
MEGZO IV fetches the invoice PDF that Számlázz.hu (or your invoicing service) already produced and attaches it to the Squarespace Commerce order where supported. It never generates a fiscal/legal invoice and never submits to e-Factura/ANAF.
Is Számlázz.hu ↔ Squarespace Commerce a good regional fit?
Számlázz.hu and Squarespace Commerce share a regional footprint (HU), so this is a native fit.
