How do I integrate PostNL (delivery, pickup-point, return)?

PostNL dominates Dutch parcel delivery and Dutch shoppers expect three things: (1) a delivery date picker at checkout (PostNL guarantees next-day for 99% of NL addresses), (2) pickup-point selection (~3,500 PostNL points in NL, Dutch shoppers love these for "delivery while at work"), and (3) a self-service return label. We use the official PostNL Magento extension or one of the popular alternatives (Tig PostNL is the de-facto choice). It wires to your PostNL business contract and adds: address-validation against the Dutch postcode + house-number database, dimensional-weight quoting, label generation directly inside the order admin, COD support if needed, and webhook-driven shipment-tracking sync back into Magento. We also integrate DHL Parcel NL as a fallback / multi-carrier option and Pakketdienst Quick for B2B same-day Randstad delivery.
