Drivers do not fill in expense forms. The Decision Layer does not expect them to.
In logistics and transport, every cross-border trip creates a tax event. GPS determines the country. Telematics determine the duration. The Travel Decision Layer processes driver per diems without a single manual entry. Zero-touch mode: the driver drives, the system decides. The EU Mobility Package adds posting documentation requirements that the audit trail covers as a data basis for compliance.
Four dimensions that office-centric expense tools miss
GPS replaces forms
Drivers cross borders multiple times per day. They cannot stop to fill in an expense form at each border. The Decision Layer reads GPS data from telematics systems and calculates country-specific per diems based on actual location and duration.
EU Mobility Package documentation
The EU Mobility Package (Directive 2020/1057) requires posting documentation for cross-border driver operations. The Decision Layer generates the data basis that compliance teams need for reporting, without creating additional burden for drivers. Legal assessment remains with specialist departments.
Fleet-wide consistency
A fleet of 500 trucks crosses the same borders daily. Inconsistent per diem calculations across drivers create audit risk at scale. The Decision Layer applies identical rules to identical routes, eliminating person-dependent variation.
Zero-touch driver mode
The driver's job is driving, not administration. The Decision Layer operates in zero-touch mode for standard routes: GPS data in, per diem calculation out, payroll export ready. Queries only for genuine exceptions.
Decision steps of a driver tour
| Step | Decision | Decider | Rationale |
|---|---|---|---|
| 1 | Read GPS track from telematics | Automatic | Data import, no decision |
| 2 | Determine country sequence and duration | Rule engine | GPS coordinates mapped to jurisdictions |
| 3 | Select per diem per country | Rule engine | Country-specific rate per applicable framework |
| 4 | Calculate midnight border crossing | Rule engine | Pro-rata calculation when crossing at midnight |
| 5 | Check long-term posting threshold | Rule engine | Duration-based thresholds per jurisdiction |
| 6 | Generate EU Mobility Package data | Automatic | Posting documentation data for compliance |
| 7 | Map to fleet cost centre | Rule engine | Vehicle to fleet, fleet to cost centre |
| 8 | Generate payroll export | Automatic | Posting-ready per diem data |
Architecture and implementation
The Travel Decision Layer runs on Gosign's enterprise infrastructure: EU data residency, containerized, multi-tenant, no external dependencies. For logistics configurations, this means: telematics interfaces for GPS data import, real-time border crossing processing, and fleet-wide per diem calculation across 30+ EU/EFTA jurisdictions. Typical pilot projects start within 3 months with one fleet group and the most-traveled routes.
Frequently Asked Questions
Does the system work with existing telematics systems?
The Decision Layer is configurable to read GPS data from standard telematics providers. The integration maps location data to tax-relevant country and duration calculations without additional hardware.
How is the EU Mobility Package handled?
The Decision Layer generates the data basis for posting documentation as required by Directive 2020/1057. This includes country of operation, duration and applicable periods. Legal assessment and regulatory reporting remain with your compliance and legal teams.
What happens when GPS data is unavailable?
The Decision Layer falls back to planned route data from dispatch systems. Cases with GPS gaps are flagged for review. The audit trail documents which data source was used for each calculation.
Can it handle mixed fleets (owned and subcontracted)?
The Decision Layer supports multi-tenant configurations. Owned fleet and subcontracted vehicles can operate under different rule sets and cost allocation models within the same system.
How complex is your logistics travel expense logic?
