Odoo and DATEV: interface, export and limits
Odoo Enterprise is a full, open ERP for all operational processes; DATEV is the German standard for accounting, tax and payroll and is not an ERP. In practice the two are often combined: Odoo as the ERP with a DATEV export to the tax advisor.
Important context: DATEV is not an ERP but the backbone of German tax, accounting and payroll and of the collaboration with the tax advisor. A "—" for DATEV therefore means "out of scope", not "worse". The two are often even combined (Odoo as the ERP with a DATEV export).

The DATEV export from Odoo: what actually gets handed over
Most people searching for "Odoo DATEV" are not looking for a winner. They want to know how the handover to the tax advisor works. In short: Odoo exports, DATEV imports, and both stay what they are.
The prerequisite is one of the German localization packages. The module "Germany - Accounting Reports" (l10n_de_reports) adds the DATEV export options to the general ledger. They are found under Accounting → Reporting → General Ledger, in the Actions menu.
There are two exports, and the order is not arbitrary: DATEV ATCH first, then DATEV DATA. The reason sits with DATEV, not Odoo: DATEV runs two interfaces, DATEV Unternehmen online for the client and DATEV Rechnungswesen for the tax advisor.
DATEV ATCH delivers the documents themselves — the PDF or image files behind invoices and bills — together with a document.xml that assigns each file a unique ID (GUID). That ZIP is uploaded through the DATEV Belegtransfer software. One catch: customer invoices must have been generated via the Send button, vendor bills received through an email alias or uploaded. Documents that reached Odoo any other way are missing from the export.
DATEV DATA then delivers the accounting as a ZIP with three CSV files: customer accounts, vendor accounts, and the journal items for the period selected in the general ledger. Those journal items carry the same GUIDs, which is how DATEV automatically links the previously uploaded documents to the individual entries. This ZIP goes to the tax advisor, who imports it into DATEV Rechnungswesen.
And the limits: the export is a handover, not a synchronisation. It runs one way, at whatever cadence you agree with your tax advisor. Payroll stays outside it. For the advance VAT return Odoo has its own module ("Germany - Elster Tax Submission", l10n_de_reports_elster) that files the UStVA electronically with the tax office — a different route from DATEV, and not part of the export.

- an end-to-end operational process flow (order-to-cash, procure-to-pay) is needed,
- openness, customisability and a modern all-in-one are desired.
DATEV is the right fit when …
- the need is mainly accounting, tax (ELSTER/E-Bilanz) and payroll,
- close, standardised collaboration with the tax advisor is central,
- legal certainty, audit/attestation readiness and DE payroll are priorities,
- no operational ERP for sales/inventory/production is needed.
Frequently asked questions: Odoo Enterprise vs. DATEV
Does Odoo replace DATEV?
Not directly. Odoo covers accounting, but ELSTER/E-Bilanz and German payroll are DATEV domains. Many businesses run Odoo as their operational ERP and hand accounting over to the tax advisor via a DATEV export.
Can I use Odoo and DATEV together?
Yes, that is the most common approach: Odoo as the ERP for sales, inventory, manufacturing and invoicing, with a DATEV export for the tax advisor and payroll.
Is Odoo GoBD-compliant for German accounting?
Yes, with the right module and setup. A document archive and GoBD-compliant processes can be implemented; for ELSTER/E-Bilanz you often fall back on the DATEV route or add-on modules in practice.
Who benefits from switching to Odoo?
Companies that, beyond accounting, need sales, inventory, manufacturing, projects or website in one system. If the need is purely tax and payroll, DATEV remains the right choice.
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.
