Connect Shopify to PostNL Fulfilment

By the KoneX Team | Last updated: September 2026

With KoneX, you can connect Shopify to PostNL Fulfilment: orders are automatically sent to the PostNL warehouse, and inventory, shipping status, Track & Trace, and returns are automatically updated in Shopify—without any manual entry. You continue to work in Shopify; KoneX handles the data exchange with PostNL Fulfilment and the rest of your Connected Commerce ecosystem.

Shopify is the most widely used e-commerce platform among growing brands in the Netherlands and Belgium. If you have PostNL Fulfilment handle your logistics, you’ll want every order to be available in the warehouse immediately, for the inventory in Shopify to match what’s actually on the shelf, and for your customer to automatically receive a tracking number.

Do you also use an ERP or accounting software package like Exact Online, or do you sell through Bol or other marketplaces? If so, a reliable, automated integration between Shopify and PostNL Fulfilment is essential for ensuring that all your sales channels and systems work together seamlessly.

Without a direct integration, you’ll quickly end up with manual exports, duplicate entries, overselling, and customers asking where their package is.

KoneX integrates with Shopify automatically with PostNL Fulfilment. No manual data entry and no unnecessary complexity. This way, your online store can grow while your systems continue to work together seamlessly.

Exact Online Shopify integration

By the KoneX Team | Last updated: July 2026

With KoneX, you can automatically connect Exact Online and Shopify, so that orders, inventory, products, returns, and financial data are automatically synchronized between your accounting system and your online store—without manual entry and without inventory discrepancies.

Do you use Exact Online as your accounting or ERP system while also running Shopify as your ecommerce platform?
Then you know how difficult it can be to keep both systems in sync, especially when dealing with Point of Sale and multiple warehouses.

Without a direct integration between Exact Online and Shopify, inventory discrepancies, manual order processing, and errors between your webshop, Point of Sale, and multiple warehouses are almost inevitable. This not only affects operational reliability but can also cost you several hours of administrative work each month. In addition, incorrect inventory levels may lead to lost revenue due to stock discrepancies.

An Exact Online-Shopify integration is an order-to-cash connection that automatically synchronizes products, orders, inventory changes, returns, and financial data between both systems—without manual entry, without delays, and without discrepancies. KoneX implements this integration automatically and fully customized to your needs.

This also works from Shopify to Exact Online, ensuring new products or updates are instantly visible in your webshop.

  • Returns and payment flows are automatically processed between Shopify and Exact Online, either automatically or in batches. Returns, refunds, gift cards, and POS transactions are immediately and accurately processed in both the accounting system and the online store.

Integrate Shopify Returns with Fulfilment

By the KoneX Team | Last updated: July 2026

With KoneX, you can connect your Shopify returns to your fulfillment partner: return requests (RMAs), tracking, processed returns, and inventory levels are automatically synchronized between Shopify and the warehouse—without manual entry and without a separate returns app.

Do you use Shopify as your ecommerce platform while relying on an external fulfilment provider for your logistics, including returns? Then you know how difficult it can be to automatically update your returns without a direct fulfilment integration.

Returns are often among the most error-prone processes in ecommerce operations. Manual returns and updates lead to errors and incorrect stock levels.
If you rely on a standard returns app, you will incur additional monthly costs and still have to manage dashboards across multiple systems.

A Shopify Returns Fulfillment integration is an automated data connection that pre-registers your Shopify returns as RMAs with your fulfillment partner and automatically synchronizes tracking numbers, processed returns, and inventory levels between both systems.
No manual entry, no delays, and no discrepancies. KoneX implements this Shopify Returns Fulfillment integration automatically and fully customized to your needs.

Custom Data Is Fully Supported

At KoneX, it’s always possible to integrate additional or company-specific data. We can also easily include extra data along with standard data packages.

We Also Connect Other Systems and Service Providers

At KoneX, we’re constantly adding new systems and data flows. It’s possible that your system isn’t listed yet, even though it’s already available. Please contact us if this is the case.

Even if you have your own custom system that features a defined Application Programming Interface (API), in most cases it’s easy to connect it via KoneX. That means you only need one integration to connect with all the systems and service providers already connected to KoneX.

Think in Data Flows, Not Just Systems

An e-commerce integration is more than just connecting two systems. It’s about properly setting up your data flows, from the online store to your front door. And it’s about ensuring seamless integration between order fulfilment and package shipping: from Pixel to Parcel.

We believe you shouldn’t automate anything until you have a clear understanding of your data flows and which systems and parties are involved throughout your entire collaboration chain with external parties, systems, and service providers.
