Running several outlets, warehouses, or regional offices inside a single Odoo company usually forces an uncomfortable choice: either spin up a separate legal company per location — inheriting the full weight of inter-company invoicing, consolidation, and duplicated master data — or leave everything in one pool where every salesperson sees every order and every P&L blends into one number. The Multi-Branch / Multi-Location Operations Manager gives you the missing middle layer: a lightweight but pervasive Branch dimension that threads through Sales, Purchase, Inventory, Point of Sale, and Accounting without fragmenting your company into separate Odoo companies.

At the data layer, ECOSIRE adds a branch_id Many2one (to a new res.branch model) onto the operational documents that matter — sale.order, purchase.order, stock.picking, account.move, pos.order, and their lines where reporting needs it. Each user is assigned one or more allowed branches via a Many2many on res.users, and record rules (ir.rule) plus ir.model.access.csv entries enforce that a branch-scoped user only reads and writes documents belonging to their branch — while managers keep the consolidated view. Because it is a genuine field on the models, the Branch flows automatically into pivot views, graph views, filters, and group-bys, so consolidated-versus-per-branch reporting is native rather than bolted on.

We wire branch defaulting the Odoo way: computed defaults derived from the user's branch, @api.onchange/@api.depends propagation from order to lines to the resulting invoice and stock moves, and per-branch document sequences (ir.sequence) so each branch numbers its own quotations, invoices, and delivery orders (e.g. INV/DXB/2026/0001 vs INV/AUH/2026/0001). QWeb report headers pick up the branch address and details, POS sessions inherit the operator's branch, and an inter-branch transfer workflow lets one location request and receive stock from another with a clean audit trail. Everything is delivered as a proper installable module — a versioned __manifest__.py, models, security CSV/XML, views, and reports — tested and installed on your Odoo 17, 18, or 19 (Community or Enterprise) by our engineers.

This is a build-to-order engagement, not an instant apps.odoo.com download. After purchase, an ECOSIRE Odoo engineer confirms your exact scope (which apps carry the Branch dimension, your access matrix, your sequence scheme), builds and hardens the module against your version and edition, installs it in staging, migrates your existing records with a branch backfill, and hands over the source. Typical lead time is 2–4 weeks depending on how many flows and the depth of the access model.
