Spare-parts businesses live and die by three things: finding the right part for the right vehicle, knowing exactly what stock sits in which bin, and quoting fast enough to keep the counter moving. Out of the box, Odoo gives you products, variants, and inventory, but it has no concept of a vehicle fitment tree (make/model/year/engine/trim), no OEM-to-aftermarket cross-reference, and no interchange/supersession lookup. Teams end up bolting fitment data into product descriptions, running parallel spreadsheets for cross-references, and bleeding margin on wrong-part returns. A typical off-the-shelf apps.odoo.com module usually solves one slice — a catalog import, say — and leaves the rest to you. This is where a purpose-built industry package earns its keep.

ECOSIRE builds a cohesive package that models the spare-parts business as first-class Odoo data. We add a fitment model (a models.Model relating parts to the vehicles they fit), an interchange/cross-reference model for OEM numbers, aftermarket equivalents, and superseded-part chains, and compute fields (@api.depends) that surface fitment coverage and substitution options directly on the product form. Counter and quotation views (XML/OWL) get a vehicle-first search: pick the vehicle, see every compatible part with live stock across warehouses. We extend stock for bin-level locations and optional core-charge (returnable core) tracking, and wire sale.order for fast counter quoting with automatic substitution when a superseded part number is requested.

Technically, everything ships as a clean, versioned Odoo module: a proper __manifest__.py declaring dependencies (sale_management, stock, purchase, and account where invoicing is in scope), models under models/, access control through ir.model.access.csv plus record rules for multi-warehouse and multi-company isolation, and QWeb reports for pick lists, counter invoices, and fitment/catalog sheets. Automated actions handle reorder alerts and supersession notices; the standard XML-RPC/JSON-RPC API stays fully usable so a webshop, marketplace feed, or POS front end can read fitment and stock without custom glue. We target Odoo 17.0, 18.0, and 19.0 and account for Community vs Enterprise differences up front — for example, if your workflow assumes barcode-driven receiving or advanced accounting, we confirm which edition you run and design to it rather than assuming Enterprise-only features exist.

Because this is build-to-order, nothing is pre-listed for instant download. After a short scoping call we confirm your catalog structure, fitment data source, warehouse layout, and Odoo version, then build against your requirements, test on a staging database, and hand over installable source with a rollback plan. Typical delivery is 2–4 weeks from confirmed scope. Pricing starts from $349 (indicative, single-company base scope); multi-company setups, deeper localization, additional integrations (webshop, marketplace, or supplier catalog feeds), and larger fitment/data-migration volumes increase the quoted scope. You receive a fixed quote after the scoping call — never a surprise bill.
