Trusted by Europe's leading organizations
DNA Solutions builds and maintains the systems telecom and media operators run their business on: OSS and BSS platforms, billing and charging engines, and the data that sits on top. We work on systems where an hour of downtime hits revenue directly.
Trusted by Europe's leading organizations
We deliver telecom infrastructure for operators of this scale, including engagements with T-Systems. Our senior team also brings charging and billing experience from Mobistar, before founding DNA Solutions. That mix shapes how we approach OSS and BSS modernization: starting from how the systems run in production rather than from a reference architecture.
We design technology that lands on your bottom line. European enterprises trust us with extreme data volumes and critical financial pipelines.

What makes telecom IT hard is keeping usage, charging, billing and the ledger in agreement. That alignment is the engineering DNA Solutions handles.
High-volume usage events have to turn into charges that add up to the cent. We build the rating logic on strict decimal types and immutable event ledgers, so millions of events aggregate without a single rounding discrepancy. Each charge traces back to the event that created it, which lets operators pass external financial audits without reconstructing data after the fact.
The system has to feed the operator's general ledger correctly. We build reconciliation pipelines that connect OSS and BSS platforms to billing, CRM and the corporate financial ledger, automating the financial close and taking manual entry out of the loop. The integration layers carry fallback mechanisms, dead-letter queues and automatic retry, so a temporary outage on one side never loses a record.
Tariffs and settlement rules change often, and each change has to apply from its effective date without rewriting historical charges. We keep tariffs and settlement as decoupled, time-windowed configuration rather than hard-coded logic, so a rate change applies cleanly.
Operators sit on data spread across the network, the charging engine, billing and CRM. We consolidate those sources into one data layer, so usage, revenue and reconciliation can be read across the operator instead of one system at a time. Every figure is reconciled against its source, so operations and finance work from the same numbers.
DNA Solutions does most of its telecom work in three areas, from provisioning and billing on the OSS and BSS side to the charging engines and data layers behind them.
What we buildWe modernize the OSS and BSS platforms behind an operator, from provisioning to billing. Monolithic systems move toward decoupled, configurable components, so a tariff or process change applies without rewriting the core.
The rating and charging core behind telecom billing: high-volume events priced as they arrive, immutable ledgers, audit-ready reconciliation. We keep tariffs as time-windowed configuration, so a rate change applies from its effective date.
We migrate legacy telecom platforms and charging engines toward maintainable, cloud-ready architecture. The new system runs in parallel with the old one, and a segment switches over only once its output matches.
Most telecom engagements lean on more than one service. These three come up most often, each with its own page.

"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."
"DNA Solutions built the backend and the app for our 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."
"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 questions telecom and media operators raise most often before an engagement.
Yes. We deliver telecom infrastructure for operators of this scale, including engagements with T-Systems. Our senior team also worked on charging and billing at Mobistar before founding DNA Solutions. The practical effect: we start from how your systems run day to day rather than from a generic blueprint.
We never run a big-bang cutover. The new charging engine runs in parallel with the old one, and reconciliation reports compare both outputs at every cycle. A segment of usage only switches over once its charges match, so revenue and compliance are never at risk during the migration. You own the result: source code, database schemas, infrastructure-as-code and documentation, on an open-source stack with no proprietary licences locked in.
Yes. Most operators already run an OSS, a BSS, a CRM and a billing platform, and the point is to connect them rather than replace them. We build reconciliation pipelines between those systems and the corporate financial ledger that automate the close and take manual entry out of the loop. The integration layers carry fallback queues and automatic retry, so a temporary outage on one side never loses a record. Most engagements start with one focused flow on your production data before any wider commitment.
Operators usually have data spread across the network, the charging engine, billing and CRM, each readable on its own but hard to read together. We consolidate those sources into one data layer, so usage, revenue and reconciliation can be read across the operator instead of one system at a time. Every figure is reconciled against its source, so operations and finance work from the same numbers.
