PostNL Shipping Connector for Odoo

The module wires PostNL's official APIs directly into your Odoo Inventory and delivery workflow. It ships as a proper Odoo addon with its own __manifest__.py declaring dependencies on delivery and stock, a delivery.carrier extension exposing postnl as a rate-and-ship delivery method, dedicated models.Model classes for shipments and tracking events, and computed fields that keep rate and status data in sync via @api.depends. Every capability is surfaced through native Odoo — the standard delivery-method picker on the sale order, a Generate Labels button on the stock.picking (delivery order), and a tracking reference that customers see on their portal.

Live rating happens at checkout and on the sale order: when a customer picks PostNL, the connector calls PostNL's rate service with the shipment's weight, dimensions and destination and returns the correct product tariff (domestic parcel, mailbox parcel, evening delivery, EU and international). Once the warehouse validates the delivery order, the module requests a shipment from PostNL, stores the returned barcode/track-and-trace code on the picking, and attaches the print-ready label (PDF, generated through PostNL's labelling endpoint) as an ir.attachment ready for the packing station. If an order is cancelled before handover, one click calls PostNL's cancellation flow and voids the label so you are not billed. A scheduled automated action (ir.cron) polls PostNL's status API and writes delivery events back to Odoo, updating the tracking timeline and — optionally — firing the order-status email to the buyer.

Security is done the Odoo way: access rights are declared in ir.model.access.csv and record rules keep shipment data scoped to the right company in a multi-company setup, so warehouse users can print labels without seeing your PostNL API secret. Credentials live in encrypted system parameters, and all PostNL calls are logged for audit and troubleshooting. Because we build to your spec, we can also expose the connector over Odoo's XML-RPC/JSON-RPC API so an external OMS or marketplace bridge can request labels programmatically.

The build supports both Community and Enterprise (rate-at-checkout on the eCommerce website requires the Website Sale flow; back-office rating and labelling work on either edition). You get the full source, so there is no black box and no per-label SaaS surcharge on top of your PostNL contract. ECOSIRE handles installation, sandbox testing against PostNL's test environment, go-live cutover and a post-launch support window.
