If you run Odoo in Algeria, you have almost certainly hit the wall where res.country_state for Algeria is either empty or holds a handful of stale province names, and there is no concept of a commune at all. Sales reps type wilaya and commune names free-hand into street2/city, spelling them inconsistently in French, Arabic, or transliterated Latin, so your customer master becomes impossible to group, filter, or map. Delivery zones, tax jurisdiction logic, and any "revenue by wilaya" pivot fall apart because the geography lives in unstructured text instead of proper records. Odoo core simply does not ship the 58-wilaya, ~1,500-commune administrative structure, and it certainly does not carry the official bilingual French/Arabic names that Algerian invoices and shipping labels require.

We build a localization module that seeds the complete, current Algerian administrative hierarchy as first-class Odoo data. Wilayas are loaded as res.country.state records scoped to Algeria (country_id = DZ), and communes are added as a dedicated model (for example x_dz_commune or a namespaced dz.commune, agreed at scoping) with a many2one back to their parent wilaya, each carrying the official code, the French name, and the Arabic name. Bilingual names are handled through Odoo's translation layer so the same record renders in French or Arabic based on the user's or partner's language, rather than being duplicated into separate columns. The data ships as versioned XML data files in the module (data/ with noupdate where appropriate) so it installs cleanly and can be re-seeded or corrected on upgrade without clobbering records you have linked to.

On the integration side we extend res.partner with a commune field and, where you want it, computed helpers via @api.depends that keep wilaya and commune consistent (selecting a commune back-fills its wilaya; changing wilaya filters the commune domain). We wire the fields into the partner form and search views (XML/OWL), add them to the address block and to relevant list/search filters and group-bys, and expose them to QWeb so invoices, delivery slips, and other reports print the correct bilingual place names. Access is governed by ir.model.access.csv for the new commune model plus record rules if you multi-company, and the data is reachable over the standard XML-RPC/JSON-RPC API so external systems and e-commerce fronts resolve the same canonical geography. The module targets Odoo 17.0, 18.0, and 19.0, works on Community and Enterprise, and its __manifest__.py declares the correct dependencies (typically base/contacts) with no reliance on Enterprise-only features unless you ask for them.

Because this is build-to-order, nothing is downloaded off a shelf: after a short scoping call we confirm the exact model naming, which fields you need on the partner, report and view touch-points, and language defaults, then build, test on a staging copy of your database, and hand over installable source. Typical delivery is 2-4 weeks from confirmed scope. Pricing starts from $299 (indicative, single-company base scope); multi-company record rules, additional integrations (e-commerce, delivery carriers, external systems), deeper localization such as postal-code or daira layers, and migrating a large volume of existing free-text addresses into structured commune records increases the quoted scope.
