Every Odoo rollout, migration or seasonal data load eventually hits the same wall: getting large volumes of real-world data into the system cleanly. Odoo's native import (the "Import records" action backed by base_import) is fine for a single tidy model, but it struggles the moment you need to load related records across res.partner, product.template/product.product, sale.order, purchase.order, account.move, stock.quant, mrp.bom, crm.lead and project.project/project.task in one coordinated pass. External IDs drift, many2one lookups fail silently on fuzzy names, tax and UoM columns don't map, and a half-imported batch leaves your ledger in a state nobody wants to unwind by hand. Spreadsheets from suppliers, legacy ERPs and marketplaces rarely match Odoo's expected column shapes — so the "quick data load" turns into weeks of manual cleanup.

This is a build-to-order module that ECOSIRE designs, builds and installs specifically for your database and your file formats. It is not an existing apps.odoo.com download — we scope it to the exact models, fields and edge cases you actually import. Technically, we ship a wizard-driven importer (models.TransientModel wizards with OWL/XML views) that accepts CSV and Excel (.xlsx) uploads, lets you map source columns to target fields per model, resolves many2one references by external ID, database ID or configurable name-matching, and validates every row against the target model's constraints before committing. Under the hood it uses the ORM (create/write in batched, savepoint-wrapped transactions) rather than raw SQL, so computed fields, @api.depends recomputes, sequences and access rules all fire correctly. Access is governed by ir.model.access.csv plus record rules so only authorized users run imports, and each run writes an audit log with per-row status and error reasons you can export.

The workflow is built for messy real data: dry-run/preview mode that reports what would be created or updated without writing; upsert by external ID or a chosen unique key so re-running a corrected file updates instead of duplicating; configurable handling for missing masters (skip, error, or auto-create the partner/product/BOM component); and per-model field maps you can save and reuse. For accounting imports we respect journal, tax and analytic requirements and can post or leave entries in draft; for inventory we can load on-hand quantities via inventory adjustments; for BOMs we resolve components and operations; for CRM and projects we map stages, teams and assignees. We build against your target release — Odoo 17.0, 18.0 or 19.0 — and account for Community vs Enterprise differences (some accounting and MRP behaviors differ), and we can expose the same import logic over XML-RPC/JSON-RPC if you need to trigger loads from an external pipeline.

Delivery is made-to-order. It starts with a short scoping call to confirm exactly which models, source file layouts and matching rules you need, followed by a fixed written quote. We then build on a copy of your data, run UAT on a staging database with your real files, and only deploy to production once you sign off — with a rollback plan in place. Typical delivery is one working week from confirmed scope, depending on how many models and how much field-mapping complexity is involved. Pricing starts from $999 (indicative, single-company base scope covering a core set of models); multi-company setups, large or multi-format source files, deep localization/tax requirements and high data-migration volumes increase the quoted scope. You receive the full installable source, documentation and a support window after go-live.
