Why Shopify + Allegro on MEGZO IV

Dynamic field mapping

Shopify's fields map to Allegro's through editable rules you control (VAT strip/add, rounding, value lookups, currency conversion), and changes take effect right away, with no code change.

Never oversell

Stock pushed to Allegro with a buffer and reconciled, so a unit can't sell twice across channels.

Orders, once

Every Allegro order becomes one record in Shopify — idempotent by design.

Shopify + Allegro — FAQ

Does MEGZO IV sync stock between Shopify and Allegro in real time?

Stock flows on a 5-minute heartbeat and on demand, with push (webhook) wake-ups where Allegro supports them. It is pushed with an oversell buffer and continuously reconciled, so you never sell the same last unit twice.

Will a Allegro order create a duplicate in Shopify?

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 Shopify.

Do I manage this from Allegro or from Shopify?

From neither — you manage Product, Price, Stock and Order syncing from your MEGZO IV vendor panel. Field mapping between Shopify and Allegro 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 Allegro?

MEGZO IV fetches the invoice PDF that Shopify (or your invoicing service) already produced and attaches it to the Allegro order where supported. It never generates a fiscal/legal invoice and never submits to e-Factura/ANAF.

Is Shopify ↔ Allegro a good regional fit?

Shopify and Allegro share a regional footprint (PL), so this is a native fit.
