What syncs between Xero and BigCommerce
Why Xero + BigCommerce on MEGZO IV
Dynamic field mapping
Xero's fields map to BigCommerce'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 BigCommerce with a buffer and reconciled, so a unit can't sell twice across channels.
Orders, once
Every BigCommerce order becomes one record in Xero — idempotent by design.
Works with your couriers & payments
Fulfilment and payment systems plug in alongside this pair — no extra integration project.
Couriers — AWB & tracking to BigCommerce
Payments — via the official plugin or a custom integration
Xero + BigCommerce — FAQ
Does MEGZO IV sync stock between Xero and BigCommerce in real time?
Stock flows on a 5-minute heartbeat and on demand, with push (webhook) wake-ups where BigCommerce supports them. It is pushed with an oversell buffer and continuously reconciled, so you never sell the same last unit twice.
Will a BigCommerce order create a duplicate in Xero?
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 Xero.
Do I manage this from BigCommerce or from Xero?
From neither — you manage Product, Price, Stock and Order syncing from your MEGZO IV vendor panel. Field mapping between Xero and BigCommerce 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 BigCommerce?
MEGZO IV fetches the invoice PDF that Xero (or your invoicing service) already produced and attaches it to the BigCommerce order where supported. It never generates a fiscal/legal invoice and never submits to e-Factura/ANAF.
Is Xero ↔ BigCommerce a good regional fit?
Xero and BigCommerce share a regional footprint (GB, AU, NZ), so this is a native fit.
