GoBD Z3 Export for Odoo: the German tax audit data package in one click

In a German tax audit the auditor can ask for the accounting data on a data carrier (Z3, Datenträgerüberlassung): CSV tables described by an index.xml in the GDPdU description standard. Odoo exports CSV and Excel, but not this package. GoBD Z3 Export builds it from your posted accounting and keeps every package with its checksum as a record of what was handed over.

Odoo GoBD Z3 export with entries, journal items, debit total, the ZIP package, its SHA-256 checksum and the export log, synthetic demo data — A finished export with its checksum

What GoBD Z3 Export does

What's inside

index.xml with columns, types, keys and validity period, the GDPdU DTD, and tables for journal items, entries, trial balance, accounts, journals, taxes and partners.

Keys that resolve

Every account, journal, tax, partner and entry a journal item refers to is in the package, and index.xml is validated against the DTD in the tests.

Every package kept

An exported package can't be edited or deleted. Period, exporter, record counts and a SHA-256 checksum per file stay with it, and it prints as a handover protocol.

Branches included

Posted entries of the company and its branches, archived branches too. Drafts and other companies never reach the package.

Text that survives

Umlauts, semicolons, quotes and line breaks stay intact, with decimal comma and DD.MM.YYYY dates.

Good to know

It covers the financial accounting data of the period. Cash register data (DSFinV-K), payroll and document archives are separate obligations.
GoBD compliance depends on your whole process, including your procedure documentation. The app produces the data package; it doesn't certify compliance.
One company per export, with its branches.
Odoo Online can't install custom Python add-ons, so it needs Odoo.sh or your own server.

FAQ

Doesn't Odoo do this already?

Odoo's German documentation describes CSV and Excel exports. The Z3 package with index.xml and the description standard is what this app adds.

Can I export again?

Yes, as a new export. Earlier packages stay as they were, so the history shows every handover.

Who can export?

Accounting administrators create exports. Read-only accounting users, for example your tax advisor, can open and download them.
