Group finance teams running several legal entities in Odoo hit the same wall every close: the accounts are clean per company, but the group picture lives in a spreadsheet. Odoo's core multi-company support lets you post in separate companies and share a chart of accounts, but it stops short of a true consolidation. There is no group ledger that revalues foreign subsidiaries at the right rates, no automatic elimination of inter-company sales, receivables, payables, and unrealised profit, and no clean split between the parent's share and the minority interest. Enterprise's account_consolidation app helps with a mapped trial balance, but it does not model FX translation reserves, ownership percentages below 100%, or a fully auditable elimination journal the way a group CFO needs for a defensible consolidated pack.

We build a dedicated consolidation layer on top of your existing Odoo accounting. At its core is a consolidation.group and consolidation.company.rel model that records each subsidiary, its ownership percentage, its consolidation method (full, proportional, or equity), and its functional currency. A consolidation.run object (a models.Model with @api.depends computed totals) pulls the period trial balance from each company via the ORM, applies currency translation per your policy — closing rate for balance sheet accounts, average rate for P&L, historical rate for equity — and books the resulting FX difference to a translation reserve. compute methods derive the parent share and non-controlling interest from the ownership percentage on every equity and result line, so minority interest falls out of the same run rather than being bolted on afterward.

Eliminations are handled as explicit, reviewable journal entries rather than hidden arithmetic. We configure elimination rules that match inter-company partners and account pairs, generate account.move elimination entries in a dedicated consolidation journal, and let controllers see and adjust them before locking the run. Every consolidated figure drills back to the underlying company, journal, and elimination that produced it — nothing is a black box at audit time. The consolidated Balance Sheet, P&L, and Cash Flow are delivered as QWeb reports (PDF and screen) plus Odoo pivot/list views, and the whole run is exposed over the XML-RPC / JSON-RPC API so a parent-level BI tool or a scheduled ir.cron automated action can trigger and read it.

Access is locked down properly: ir.model.access.csv grants plus record rules scope each user to the entities they may consolidate, and the run states (draft, computed, locked) gate who can post eliminations or reopen a period. The module ships as a proper Odoo addon with a versioned __manifest__.py, targeting your exact Odoo edition and version (17.0, 18.0, or 19.0), and respecting Community vs Enterprise differences — for example layering cleanly alongside Enterprise's consolidation app where present, or standing alone on Community.

This is a build-to-order engagement, not an off-the-shelf download. It starts with a scoping call to capture your entity structure, ownership tree, currency policy, and the exact elimination and reporting rules you need. We build against your requirements, deliver on a UAT staging environment for you to validate a real period-end close, then install to production with a rollback plan and a handover of the git repository. Typical delivery is 2-4 weeks from confirmed scope, depending on the number of entities and the complexity of your elimination and FX rules.
