Which exports matter and how to match logs with invoices and delivery notes? 19 September 2026 ## Quick answer For partners, a digital logbook usually serves as the legally secure primary record if it provides correct entries, tamper‑proof storage and exportable formats. GPS tracking adds position and timestamp evidence, but alone it often lacks the formal structure needed for tax logbooks. Check tools for tamper protection, audit trails, export options (CSV, PDF/A, XML), timezone handling and location accuracy. Matching logs to invoices and delivery notes improves audit readiness for tax and client checks. ## Why the difference matters Partners and subcontractors document trips with apps or telematics. A digital logbook is built to meet tax and legal requirements. GPS tracking provides raw position and time data. Raw GPS alone usually does not satisfy auditors. Traceability and tamper‑proof storage are the key factors. ## Key checks for partners Check: 1) Tamper protection: Are entries stored immutably? 2) Audit trail: Are change logs available with user and timestamp? 3) User flow: Can trips be marked business or private easily? 4) Required fields: start/stop, purpose, odometer, date/time. 5) Data protection: local storage or compliant processing under Swiss law. ## Which export formats do auditors want? Useful exports are: CSV for spreadsheet analysis, PDF/A for readable archive copies, XML for structured data exchange. Some tax offices or auditors prefer specific formats. A robust tool offers all three plus metadata (device, app version, hashes). ## Using GPS logs correctly Use GPS data as supporting evidence. GPS logs show routes, stops and timestamps. For tax acceptance you must link GPS records to the logbook entry: same trip ID, matching times and a documented purpose. Avoid relying on map screenshots alone. ## Matching logs with invoices and delivery notes Automate matching to reduce manual work. Check: date/time alignment, start/stop matches, odometer differences, signatures or electronic proof of delivery (POD). Flag mismatches for follow‑up. A clear document chain increases trust with clients and auditors. ## Practical tips for x25pronto partners Choose a digital logbook app that exports CSV/PDF/A/XML and provides audit logs. Combine it with GPS tracking for extra evidence. Archive exports by month, vehicle and job. For audits provide: exported logbook, linked GPS logs, delivery notes and invoices in one ordered folder. ## Frequently asked questions Can GPS tracking replace a logbook? Not fully. GPS gives important raw data but often lacks the formal requirements for a tax‑approved logbook. Better to use a digital logbook plus GPS as backup evidence. Which exports should I keep for a tax audit? Keep CSV for analysis, PDF/A for readable archiving and XML when structured transfer is needed. Include metadata and audit logs. How do I prove a trip to a client or auditor? Provide the logbook entry, GPS log with timestamps and the delivery note/invoice together. Store these documents together and reference a common trip ID. What about data protection? Minimise personal data. Use pseudonymisation, set clear retention periods and inform drivers and clients about purpose and storage time. ## Courier partners at x25pronto Switzerland x25pronto Switzerland works with independent drivers for suitable trips.
