Marketing teams running Odoo eCommerce and Website consistently lose attribution once a customer moves past the cart. Odoo core fires basic tracking pixels client-side, but browser ad-blockers, consent gating, and iOS tracking prevention silently drop a large share of those events — so your ad platform under-reports conversions, optimizes against noisy data, and your reported ROAS drifts from what actually landed as a confirmed sale.order. Native Odoo has a Website Settings field for a tag manager container ID and a handful of front-end events, but it has no server-side event API, no hashed first-party data for enhanced conversions, no deduplication key shared between browser and server, and no reconciliation against the real order lifecycle. That is where teams run out of road.

We build a dedicated Odoo module that owns the full enhanced-conversion pipeline. On the front end, the module injects a structured dataLayer at the right lifecycle moments (product view, add-to-cart, begin_checkout, purchase) using QWeb templates and OWL components hooked into the website checkout controllers, each event carrying a stable transaction_id derived from the order reference. On the back end, a new model (models.Model with fields, @api.depends computes, and ir.model.access.csv plus record rules for security) mirrors every marketing event and exposes a server-side dispatch layer: when an order is confirmed or paid, an automated action / server action queues a server-side conversion call so the sale is reported even if the browser event never fired. First-party identifiers (email, phone) are SHA-256 hashed and normalized before they ever leave your server, so enhanced conversions are matched without exposing raw PII. The shared transaction_id lets the tag manager deduplicate browser and server hits, ending double-counting.

Technically, everything lives in a proper Odoo module: __manifest__.py declaring dependencies (website_sale, website), models under models/, views and QWeb assets under views/, security under security/, and configuration surfaced through res.config.settings so container IDs, consent mode defaults, hashing keys, and per-event toggles are managed in Settings rather than hard-coded. Confirmed conversions and any transmission failures are logged to a queryable model with a QWeb report and a list/pivot view, giving marketing and finance a single reconciliation surface between analytics, the ad platform, and Odoo's own order data. Where you already push orders through the XML-RPC/JSON-RPC API from external systems, we expose a clean hook so those flows also emit conversions. We support Odoo 17.0, 18.0, and 19.0, and account for Community vs Enterprise differences (Enterprise's marketing-automation and subscription models get first-class event hooks where present).

Because this is build-to-order, nothing ships until we scope it with you. After a short scoping call we confirm your data layer, event taxonomy, consent requirements, and target Odoo version, then build, test on a staging instance with UAT and a rollback plan, and hand over installable source with a git repository and documentation. Typical delivery is one working week from confirmed scope. Pricing starts from $999 (indicative, single-company base scope); additional integrations (multiple ad/analytics platforms, server-side container hosting), multi-company or multi-website setups, and consent-mode/localization depth increase the quoted scope.
