In short: MEGZO Integrator Vortex connects Számlázz.hu and Walmart Marketplace so your catalog, prices and stock publish from Számlázz.hu to Walmart Marketplace automatically, and every Walmart Marketplace 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 Walmart Marketplace — automatically, both directions, with no double data entry and no overselling.
Számlázz.hu's fields map to Walmart Marketplace's through database-backed, versioned rules — VAT strip/add, rounding, enum lookups, currency conversion — editable without a deploy.
Stock pushed to Walmart Marketplace with a buffer and reconciled, so a unit can't sell twice across channels.
Every Walmart Marketplace 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 Walmart Marketplace 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 Walmart Marketplace 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 Walmart Marketplace 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 Walmart Marketplace (US).
We run the sync; you watch it from one dashboard. Tell us your setup and see it live on a 5-minute heartbeat.
