Carrier integration

Posti FLS 4PL + Shopify integration

nShift Delivery connects Posti FLS 4PL to your Shopify store through one multi-carrier platform. Once linked, Posti FLS 4PL delivery options appear at your Shopify checkout, and every order flows into a single dashboard for labels, tracking and returns. No per-carrier code to maintain — you manage Posti FLS 4PL alongside 207 carriers from one place.

What connecting Posti FLS 4PL gives you

Posti FLS 4PL is one of 207 carriers available through nShift Delivery. Connecting Posti FLS 4PL lets you offer its delivery options to recipients at checkout, generate Posti FLS 4PL shipping labels automatically, and switch or add carriers later without rebuilding your setup. You stay free to choose the best carrier for each order, market or service level.

How the Shopify integration works

The Shopify integration brings live delivery options into your online store's checkout, so recipients pick their preferred Posti FLS 4PL option before they pay. Orders sync from Shopify into nShift Delivery, where labels, customs documents and tracking are handled automatically. Setup takes under 5 minutes and needs no developer work on your Shopify store.

From a single workflow you generate Posti FLS 4PL shipping labels, send branded order tracking that keeps recipients on your Shopify brand, create customs documents for cross-border orders, and manage returns — all automated as orders come in. As your volumes grow, the same multi-carrier setup scales across markets without adding manual fulfilment steps.
