Finance teams that run Odoo but keep their books in a separate online accounting platform end up maintaining the same data twice. Sales orders, invoices, credit notes, customer records, product masters, and payments originate in Odoo, then get re-keyed or CSV-imported into the accounting tool, where one mismatched tax code or a renamed account quietly breaks reconciliation. Odoo core ships no native bridge to an external cloud accounting service, and its own account.move postings assume Odoo is the ledger of record. Once you decide the external platform stays authoritative for the books, that gap is real and it does not close on its own.

ECOSIRE builds a made-to-order integration module for Odoo 17.0, 18.0, or 19.0 that keeps the two systems aligned in whichever direction your process actually needs. Technically it is a proper Odoo addon: a __manifest__.py declaring dependencies (account, sale, stock as applicable), new models.Model classes that hold external-ID mappings and per-record sync state, compute/@api.depends fields for status and last-synced timestamps, and stored links so a product.product, res.partner, sale.order, or account.move in Odoo carries its counterpart record id. Synchronization runs against the accounting platform's official REST API over OAuth 2.0 (tokens stored encrypted, refreshed automatically), driven by ir.cron scheduled jobs plus optional automated actions on save. We map your chart of accounts, tax codes, payment methods, and product/customer identity rules explicitly during scoping, so a posted invoice lands against the correct account and tax line rather than a best-guess default.

The connector is engineered to be safe under real-world conditions. Every sync is idempotent and keyed on external ids to prevent duplicates on retry; API failures and rate limits are caught, logged to a dedicated ir.logging-backed audit model, and retried with backoff rather than left half-applied. A conflict policy you choose at scoping time (Odoo-wins, accounting-platform-wins, or newest-timestamp-wins per entity) governs bidirectional fields. Access is locked down with ir.model.access.csv plus record rules so only authorized finance roles can view credentials or trigger a manual resync, and multi-company installs scope every mapping by company_id. Views are delivered as standard XML/OWL screens — a sync dashboard, per-record status, and a manual "resync" action — with a QWeb-rendered reconciliation report if your team wants a printable trail.

Because this is build-to-order, nothing ships until we agree on scope. We start with a short scoping call, confirm which entities and direction you need, document field mappings and edge cases, then build on a staging copy of your database, run UAT with your data, and only cut over with a rollback plan in place. Typical delivery is one working week from confirmed scope. Pricing starts from $999 (indicative, single-company base scope covering one entity direction and a standard chart of accounts); multi-company consolidation, additional synced entities, deep tax/localization mapping, and historical data-migration volume increase the quoted scope. You receive a fixed quote after the scoping call — the from-price is a starting point, not a firm total.
