Once your Odoo inventory spans more than one warehouse, the native access model starts to leak. Out of the box, Odoo scopes stock through the stock.warehouse and stock.location models, but a user with the Inventory / User group can generally see and transact against every warehouse in the company. There is no built-in "this operator only works in the Karachi DC" boundary — pickers see other sites' operations, transfer wizards list every source location, and inventory adjustments can be posted anywhere. For multi-site operations, third-party logistics, or franchise networks this is both an operational nuisance and a genuine control and audit risk.

Warehouse Access Management is a made-to-order module ECOSIRE builds to close that gap. We introduce an explicit user-to-warehouse assignment (typically a many2many from res.users to stock.warehouse, plus an optional default warehouse per user) and enforce it with Odoo ir.rule record rules on the core stock models — stock.picking, stock.move, stock.quant, stock.location, and inventory adjustments — so a user only ever sees, creates, or validates operations for their assigned sites. The rules are written against a computed set of allowed warehouse and location IDs so they hold consistently in list views, form views, search filters, reports, and the XML-RPC/JSON-RPC API alike — not just the UI. We layer group-based operation gating (view vs. transact vs. validate vs. adjust) on top via ir.model.access.csv and dedicated security groups, and we can constrain the source/destination location selection in transfer and internal-move flows so users cannot route stock outside their remit.

Technically, the build is a clean, upgrade-safe addon: a versioned __manifest__.py, model extensions using models.Model inheritance and @api.depends computed fields for the allowed-warehouse set, security groups and record rules in data XML, adjusted views (XML/OWL) that hide or filter warehouse selectors, and optional QWeb report footers or automated actions (base.automation) to log and alert on out-of-scope access attempts. Every access decision is auditable — we can wire an access-log model and expose it as a filterable list plus an optional QWeb report. The module is delivered for your target Odoo series (17.0, 18.0, or 19.0) and is written to respect Community vs. Enterprise differences in the inventory app so the same access boundaries apply whichever edition you run.

Delivery is build-to-order, not an instant download. It starts with a scoping call where we map your warehouses, roles, and the exact operations each role may perform, then we confirm scope in writing. Typical delivery is 2–4 weeks from confirmed scope, depending on how many role/warehouse combinations, edge-case flows (drop-ship, inter-warehouse transfers, returns), and existing customizations we must account for. You receive the installable source, install and configuration on your environment, documentation, a training session, and a post-go-live support window. Pricing starts from $249 (indicative, single-company base scope); additional warehouses, complex multi-company or inter-company routing, deeper operation-level gating, and integration with existing custom inventory modules increase the quoted scope.
