Exactly the right things,

Behind the integration

What makes an integration reliable

A reliable integration is more than connecting two systems. It means defining field mapping and data ownership, handling webhooks and API limits, and building in retries, reconciliation and monitoring so critical data keeps moving reliably across Shopify, ERP, POS and the rest of your infrastructure.

When an existing connector fits the process, we use it. When the business logic is more complex, we build the integration layer around it — based on the systems involved, data volume, operational risk and how the business actually works.

For one retailer, we send sold quantities to Xentral as individual stock movements instead of overwriting stock totals. Online orders keep their changes, and every adjustment can be traced.

System architecture

How your systems work together

Your store and the systems around it each have their own role. We build the layer between them, so data moves reliably across the entire operation.

Proven in practice

Vom Einfachen das Gute

German specialty food retailer

Shopify POS · Mettler Toledo scales · Xentral ERP · Custom middleware

Challenge

The retailer sells weighed goods across physical stores. Shopify had to become the single master system for products, barcodes and sales, including items sold by weight. The scales, the POS and the Xentral ERP each needed the same data, in their own format.

What we built

Middleware that generates barcodes for weighed and per-piece items and syncs products to Mettler Toledo scales. A Shopify POS extension that reads the scale’s barcode and adds the weighed item to the cart automatically. An admin panel for barcode rules with a full audit log. A nightly sync that sends sold weights per store and per SKU to Xentral as stock movements, without overwriting stock changed by online orders.

What’s included

  • Scale integration

    Products reach the scales automatically, and scale barcodes are read at checkout.

  • POS extension

    Staff see and create barcodes directly on the POS terminal.

  • Xentral stock sync

    Sold weights move into the ERP every night, with every change traceable.

  • Multi-store

    One setup serves every location and every future store.

Our Process

From mapping the complexity
to a system that works.

  1. Stage 01

    Map the System

    We map every system, workflow and dependency, and define what data each one owns before deciding how they should connect.

  2. Stage 02

    Plan the Logic

    We define how data should move, what happens when systems disagree and where custom logic is needed before anything gets built.

  3. Stage 03

    Build & Test

    We build the integration layer, apps and automations, then run real scenarios through them — including the ones that fail.

  4. Stage 04

    Launch & Monitor

    We launch under real conditions and keep watching the critical flows, because integrations need to keep working after go-live.

FAQ

Questions we get asked

Who will we be talking to?

Sofiia Zabrodska, our Business Development & Sales Manager, handles the first contact and proposals. For German-speaking clients, Alexander Karl, our Country Manager DACH, is your contact in German. Our team builds and supports the system.

Can you connect Shopify to our ERP?

Yes. We have built integrations with Xentral, Odoo and custom ERPs. Other systems connect through their API, and where there is no usable API, we build the connector.

Can Shopify POS work with scales and weighed goods?

Yes. We connected Shopify POS to Mettler Toledo scales, so barcodes on weighed items are read at checkout and sold weights flow into the ERP.

How long does an integration take?

A single well-documented connection takes weeks. A multi-system build takes months, mostly in discovery. We scope it before quoting.

What happens if something breaks after launch?

We monitor the connections we build, alert on failures, and can take over maintenance when either side’s API changes.

Does our store need Shopify Plus?

Not always. Plus matters for high API volume or custom checkout logic. We tell you during scoping.
