Annual savings across European clients
By optimizing software licensing fees for several European organizations, we delivered over €1M in annual cost savings.
DNA Solutions builds and maintains the systems operators run their business on: toll backends, cross-border road charging, billing and the analytics that sit on top. We work on infrastructure where an hour of downtime hits revenue directly.
Trusted by Europe's leading organizations
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.

We design technology that lands on your bottom line. European enterprises trust us with extreme data volumes and critical financial pipelines.

We built and maintain a Deloitte-audited billing platform processing €300M in audited transactions every month.
T-Systems, Satellic, European Commission: our longest engagements last because we deliver.

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.
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.
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.
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.
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.
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 BuildWe 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.
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.
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.
Toll operators rarely need just one of these. The three below come up in most engagements, each with a page of its own.

A few projects we've built and maintained for European toll and road operators.
Senior decision-makers at the toll and road operators we work with.
"DNA Solutions built the backend and the app for our highway toll system. Of all the partners we evaluated, they were the best fit, both on the technical side and in how they worked with our team."
"DNA works with us to deliver digital systems at scale so that we can serve our customers digitally. They are both reactive to requests and proactive with ideas and proposals."
"I appreciated the collaborative spirit and the effort to deliver a reliable solution within a reasonable budget. The step-by-step approach with a demo before deployment made all the difference."
The points toll operators usually raise before they start.
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.

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.
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.
