GoBD Compliance

Audit-proof email archiving for German businesses under the Principles for Proper Management and Storage of Books, Records and Documents in Electronic Form (GoBD)

What is GoBD?

GoBD (Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in elektronischer Form sowie zum Datenzugriff) is a German administrative regulation from the Federal Ministry of Finance defining requirements for electronic bookkeeping, record-keeping, and tax-relevant document retention.

GoBD applies to all businesses subject to German tax law, regardless of size. Non-compliance can result in rejected bookkeeping, estimated tax assessments, and penalties.

2025 E-Invoicing Compliance

📄

As of January 2025, Germany mandates e-invoicing for B2B transactions. The July 2025 GoBD amendment clarifies that e-invoices (ZUGFeRD, XRechnung) must be stored in their original format.

Piler automatically complies because all email attachments are stored in their original format without modification.
