Why toll operators need a specialist
DNA Solutions has supported Toll4Europe and Satellic with software engineering and digital services.
Those engagements shaped how we engineer the chain from road event to settled revenue: charges that add up to the cent, each one traceable back to the passage that created it.

Long-term client relationships
Several clients have worked with DNA Solutions for six years. We continue to develop and support their software as their needs evolve.
From road events to settled revenue
A toll charge starts as a gantry passage or a GPS point and has to end as an audited line on an invoice. Keeping that chain exact is what DNA Solutions engineers here.
Event rating and precision
GPS positions and gantry passages must become charges that add up to the cent. We use strict decimal types and immutable event ledgers so millions of events aggregate without rounding discrepancies. Every charge traces to its source event for external financial audits.
SAP and back-office integration
We connect ERP and business applications through an integration layer. Data validation, format translation and traceable exception handling support consistent records and reduce manual transfers. Failed records can be reviewed and corrected without replaying the whole exchange, while clear ownership and monitoring help teams maintain the connection over time.
Cross-border road charging
One vehicle journey can cross several countries, each with its own tax, settlement and interoperability rules. We keep tax and settlement as decoupled, time-windowed configuration rather than hard-coded logic, so a rate change applies from its effective date without rewriting historical charges.
Operational data and analytics
Operators sit on data spread across gantries, GPS feeds, billing and the back-office. We consolidate those sources into one analytics layer, so traffic, revenue and reconciliation can be read across the whole network instead of one system at a time. Every figure is reconciled against its source, so operations and finance work from the same numbers.
Tolling platforms by DNA Solutions
Three areas cover most toll engagements: the back office that records and invoices passages, cross-border pricing, and the analytics that read across the network.
What We BuildBack-office and billing systems
The systems that record passages, price them, invoice and reconcile to the cent, with the ERP integration that ties the back-office to finance.
Cross-border charging and pricing
Pricing engines evaluate gantry and GPS events as they arrive and apply each country's tax and settlement rules as time-windowed configuration, so a peak in telemetry never slows the platform.
Operational data and analytics
Data unified from gantries, GPS feeds, billing and the back-office into one analytics layer. Traffic, revenue and reconciliation read across the whole network, each figure traceable to its source.
Services European toll operators rely on
Toll operators rarely need just one of these. The three below come up in most engagements, each with a page of its own.

Questions about tolling and road charging
The points toll operators usually raise before they start.
How do you handle cross-border interoperability and EETS?
The same vehicle journey can be subject to different tax, settlement and interoperability rules from one country to the next. We treat those rules as time-windowed configuration rather than hard-coded logic, so a rate or settlement change applies from its effective date without rewriting historical charges. EETS, where a single contract covers tolls across networks, sits on the same model: charges are computed per domain, then settled according to each domain's rules. It is the kind of multi-country work DNA Solutions runs across five European countries today.
Can DNA Solutions integrate with our existing back-office?
Yes. Most operators already run a back-office, an ERP and a set of operational systems, and the point is to connect to them rather than replace them. Which systems we connect, and in what order, is agreed with you based on the applications already in place. Most engagements start with one focused flow on your production data before any wider commitment.
How do you migrate a legacy billing system without disrupting operations?
We never run a big-bang cutover. The new platform runs in parallel with the old one, and reconciliation reports compare both outputs at every billing cycle. A segment of traffic only switches over once its charges match to the cent, so revenue and compliance are never at risk during the migration. You own the result: source code, database schemas, infrastructure-as-code and documentation, deployed on your own cloud account or on-premise, on an open-source stack with no proprietary licenses locked in. Ongoing support stays optional.
Can DNA Solutions give us analytics across all our toll points?
Operators usually have data spread across gantries, GPS feeds, billing and the back-office, each readable on its own but hard to read together. We consolidate those sources into one analytics layer, so traffic, revenue and reconciliation can be read across the whole network instead of one system at a time. Every figure is reconciled against its source, so operations and finance work from the same numbers.
