In short: MEGZO Integrator Vortex connects Billingo and Coupang so your catalog, prices and stock publish from Billingo to Coupang automatically, and every Coupang order flows back into Billingo as one record — on a 5-minute heartbeat, with oversell protection and no double data entry.
Keep Billingo as your single source of truth and let MEGZO Integrator Vortex sync your catalog, prices, stock and orders to Coupang — automatically, both directions, with no double data entry and no overselling.
Billingo's fields map to Coupang's through database-backed, versioned rules — VAT strip/add, rounding, enum lookups, currency conversion — editable without a deploy.
Stock pushed to Coupang with a buffer and reconciled, so a unit can't sell twice across channels.
Every Coupang order becomes one record in Billingo — 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 Coupang 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 Billingo.
From neither — you manage Product, Price, Stock and Order syncing from your MEGZO IV vendor panel. Field mapping between Billingo and Coupang 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 Billingo (or your invoicing service) already produced and attaches it to the Coupang 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 Billingo (HU) and Coupang (KR).
