In Austria the focus is on complete, orderly and traceable retention with verifiable audit trails. Start with stable file formats, certified timestamps and organizational measures like access control, retention rules and change logs. ## Why audit-proof matters for delivery records Delivery records document legal and commercial events. Audit-proof archiving protects against tampering, ensures traceability for tax audits and legal disputes, and supports internal controls. ## Technical basics: formats and metadata Use durable, open formats such as PDF/A for records. Add structured metadata: shipment ID, recipient address, delivery timestamp, external references. Metadata makes search, audit and automated reporting reliable. ## Timestamps and certified time sources A reliable timestamp proves when an event happened. Use qualified timestamps per ETSI TS or services with verifiable time sources (UTC-based NTP with audit). Embed timestamps in file metadata and audit logs. ## Technical and organizational measures (TMA) TMA cover roles, access rights, backups and logging. Define archive owners and regular review cycles. Set and document retention periods and deletion workflows according to legal requirements. ## Audit logs and integrity checks Apply hash-based integrity checks (e.g. SHA-256) to each file. Store checksums separately from the archive, preferably in a WORM-capable system. Keep audit logs audit-proof with timestamps, user IDs and verification results. ## Retention, retrieval and export Organize the archive with clear indexes (shipment ID, date, sender). Provide export functions that bundle records with metadata, timestamps and audit logs. This simplifies responses to tax auditors or courts. ## Frequently asked questions Which legal rules apply in Austria? Tax-relevant records are subject in particular to the retention duties under sections 131 and 132 of the Austrian Federal Fiscal Code (BAO); section 212 of the Austrian Commercial Code (UGB) is also relevant for commercial records. Electronic archives must preserve complete, orderly and content-identical reproduction throughout the retention period. Is a scanned PDF enough for audit-proof storage? A scanned PDF can be sufficient if it is PDF/A-compliant, contains metadata, undergoes integrity checks and is covered by documented organizational measures. A plain image without audit controls is risky. How long must delivery records be kept? Retention depends on the document type. Many accounting records and receipts must generally be retained for seven years; longer periods may apply to specific documents. Verify the specific retention rules for your documents and document your retention policy. What about access control? Access control prevents unauthorized changes. Use role-based rights, logging and multi-factor authentication for critical access. Store logs in an audit-proof way. ## Plan a courier trip in Austria x25pronto Austria carries small and well packed shipments by car. Businesses can choose a direct courier trip or overnight service.
