In short: MEGZO Integrator Vortex connects Számlázz.hu and Etsy so your catalog, prices and stock publish from Számlázz.hu to Etsy automatically, and every Etsy order flows back into Számlázz.hu as one record — on a 5-minute heartbeat, with oversell protection and no double data entry.
Keep Számlázz.hu as your single source of truth and let MEGZO Integrator Vortex sync your catalog, prices, stock and orders to Etsy — automatically, both directions, with no double data entry and no overselling.
Számlázz.hu's fields map to Etsy's through database-backed, versioned rules — VAT strip/add, rounding, enum lookups, currency conversion — editable without a deploy.
Stock pushed to Etsy with a buffer and reconciled, so a unit can't sell twice across channels.
Every Etsy order becomes one record in Számlázz.hu — idempotent by design.
Fulfilment and payment systems plug in alongside this pair — no extra integration project.
Stock flows on a 5-minute heartbeat and on demand, with push (webhook) wake-ups where Etsy supports them. It is pushed with an oversell buffer and continuously reconciled, so you never sell the same last unit twice.
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.
From neither — you manage Product, Price, Stock and Order syncing from your MEGZO IV vendor panel. Field mapping between Számlázz.hu and Etsy is dynamic and database-backed; a non-developer can remap a field and it takes effect without a deploy.
MEGZO IV fetches the invoice PDF that Számlázz.hu (or your invoicing service) already produced and attaches it to the Etsy order where supported. It never generates a fiscal/legal invoice and never submits to e-Factura/ANAF.
Selling cross-border? MEGZO IV's canonical model with built-in currency conversion bridges Számlázz.hu (HU) and Etsy (US/GB/DE/FR/CA).
