Odoo Enterprise vs. Accountable
Accountable is a mobile-first tax app for solo self-employed people that covers invoices, expenses and the complete tax return including ELSTER filing, while Odoo Enterprise is the full ERP for operational processes such as CRM, inventory, manufacturing and website: Accountable for sole traders without a tax adviser, Odoo for growing companies.
For solo self-employed people, Accountable largely replaces the tax adviser: invoices, expenses and, as a special feature, the complete tax return (income-surplus statement, VAT, income tax) filed directly with the tax office via ELSTER. A "—" means "out of scope", not "worse". Odoo is the overall ERP; Accountable the tax app for sole traders.

Frequently asked questions: Odoo Enterprise vs. Accountable
Does Odoo replace Accountable?
Only partly. Odoo covers invoices, expenses and double-entry bookkeeping, but does not deliver the complete tax return with direct ELSTER filing for Germany turnkey. That is precisely Accountable's core strength for solo self-employed people.
Can I use Odoo and Accountable together?
The two systems target different users and are rarely run in parallel. A sole trader typically uses Accountable, while a growing company switches to Odoo and connects the tax adviser via DATEV export.
What sets Odoo and Accountable apart on the tax return?
Accountable produces the income-surplus statement, VAT and income tax returns and files them directly with the tax office via ELSTER, including the advance VAT return out of the box. Odoo supports the advance VAT return only to a limited extent and offers no complete tax return with ELSTER filing for Germany.
For whom is switching to Odoo worthwhile?
The switch is worthwhile as soon as, beyond tax and accounting, operational processes such as CRM, inventory, manufacturing, website or projects are needed, or double-entry bookkeeping and a balance sheet are required, for example with a GmbH or UG. For scaling and broad customisation, Odoo is the platform.
Comparing more than two systems?
This comparison puts Odoo against one competitor. If several systems are still open, a structured selection is the better route: requirements first, weighted into must, should and could, then a comparison that justifies every rating. We disclose there where we earn from a system ourselves.
