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.
