If you ship domestic and EU parcels through Deutsche Post DHL as a business customer (Geschäftskunde), the daily grind is manual: rekeying addresses and weights into a separate portal, downloading label PDFs, and copying tracking numbers back into Odoo by hand. Odoo core gives you delivery and stock_delivery with a generic delivery.carrier, but out of the box it only knows fixed-price and rule-based rates — there is no live rating, no label generation, and no tracking write-back for the German Post & Parcel network. The Enterprise carrier integrations that do exist cover an entirely different express product line, not the domestic Paket / Warenpost / Europaket products your German customers expect. That gap is exactly where a typical off-the-shelf apps.odoo.com module runs out of road too: many are thin wrappers, hard-code a single product, or stop at rating without ever closing the tracking loop.

We build a clean-room connector implemented directly against the DHL Parcel DE Shipping (Post & Parcel Germany) REST API. It ships as a proper Odoo module with its own __manifest__.py declaring dependencies on delivery, stock_delivery, sale_stock and website_sale. A new delivery.carrier provider stores your GKP business-customer credentials, billing numbers and account configuration on encrypted settings fields. The rating path implements rate_shipment() to call the live API by weight, dimensions and destination zone; send_shipping() requests the label and writes the tracking number, carrier tracking URL and the label document back onto stock.picking. Labels are returned as PDF or ZPL (for thermal printers), stored as ir.attachment and surfaced on the delivery order and via a QWeb report. cancel_shipment() voids a shipment or label as long as the daily manifest has not yet closed. Weight and dimension validation runs before every label call via @api.depends computed fields and constraints, so a bad package never burns an API request.

Beyond the basics, the build covers the value-added services your operation actually uses: product selection across Paket, Warenpost and Europaket; Ident-Check and visual age check; cash on delivery; return-label (Retoure) generation; and Packstation / Postfiliale delivery-address handling so customers can ship to a locker or branch. For non-EU destinations we generate the customs / CN23 export documents from the sale and product data already in Odoo. A batch action lets warehouse staff select many pickings and print labels in one pass. Access is governed by ir.model.access.csv plus record rules so only shipping roles can touch credentials and cancel shipments, and the whole flow is scriptable over Odoo's XML-RPC / JSON-RPC API for WMS or middleware integrations. The module targets Odoo 17.0, 18.0 and 19.0, Community and Enterprise, with the version-specific OWL/view differences handled per release.

Because this is built to order, nothing installs instantly: after a short scoping call we confirm the exact products, value-added services and warehouses in play, then build, test on a staging copy of your database, and hand over installable source. Typical delivery is one working week from confirmed scope. Pricing starts from $999 (indicative, single-company base scope); multi-company or multi-warehouse setups, additional carrier products and value-added services, deeper localization, and migration of historical shipment/tracking data increase the quoted scope. You receive a fixed quote after the scoping call, never a surprise invoice.
