Discovery

Understanding your reality before writing a single line of code

We map your business processes, technical landscape, and pain points. No assumptions, just deep listening. The goal: a shared understanding of where you are and where you need to go.

Scoping

Define the right scope from day one

Stakeholder collaboration clarifying objectives, features, and delivery timelines ensures focused development. Clear priorities on what ships first, what waits, what never happens prevent scope creep. Realistic estimates accounting for integration complexity, regulatory requirements, and organizational readiness.

Design

User-centric design for maximum adoption

Prototypes tested with actual users performing real workflows. Design matching the operational patterns of your teams' daily work. Interfaces intuitive for high-frequency use. Validation with operators before development investment prevents rebuilding after launch.

Development

Maintainable solutions using production-proven practices

Event-driven architecture preventing data loss during surges. Microservices enabling independent component scaling. Clean code standards ensuring internal teams maintain systems long-term. Continuous integration catching problems early. Security and compliance designed in from inception.

What We Build

Industries relying on DNA Solutions for critical systems

For over six years, DNA Solutions has built and maintained mission-critical systems for major European enterprises across tolling, telecom, and government. Our industry-focused solutions replace inefficient legacy infrastructure, reduce costs, and meet strict regulatory and performance requirements to deliver measurable results.

Your Industry

Questions about enterprise transformation

Enterprise IT projects involve significant investment and operational risk. Before committing, you need straight answers about costs, timelines, expertise, and what happens when things don't go as planned. Here are the questions decision-makers ask us most (and our honest responses).

Let's Talk
DNA Solutions builds and modernizes the mission-critical platforms European enterprises run on: billing and charging engines, tolling and road-charging systems, and the legacy Oracle and SAP infrastructure underneath. Our work covers legacy modernization, enterprise system integration, cloud migration, and custom software development, with AI and automation added where they deliver measurable value. The results are concrete, like over €1M in annual savings we have delivered for clients.
Costs vary significantly based on scope. At DNA Solutions, a targeted proof-of-concept typically takes 8 to 12 weeks, with pricing tailored to your specific use case. A full platform modernization depends on the complexity of the existing system, integration requirements, and transaction volume. Key cost factors include discovery and scoping, development, infrastructure, and ongoing maintenance. European enterprises should budget for both the initial implementation and 15-20% annual maintenance costs. Contact us for a detailed quote based on your situation.
Yes. Keeping the existing system running is a core requirement of our delivery approach:
  • Phased delivery: we replace components step by step, with clear validation gates before each switchover
  • Parallel running: the legacy system and the new platform run side by side until the new one is proven on real data
  • Resilient architecture: event-driven design prevents data loss during traffic surges and migration windows
  • Continuous monitoring: issues are detected and resolved before they have operational impact
  • Documentation and training: your internal teams can operate and maintain the platform independently after handover
DNA Solutions works with European enterprises in toll and road infrastructure (multi-country billing, road charging), telecom and media (charging engines, subscriber platforms), fleet management (telematics data, operational intelligence), and retail and distribution (customer data platforms, demand forecasting). These industries share the same constraints: high transaction volumes, strict regulatory requirements, and platforms that cannot afford downtime. Organizations processing large transaction volumes on aging systems see the fastest return from working with us.
It depends on the scope. A targeted proof-of-concept, validating an AI use case on your own data and systems, typically takes 8 to 12 weeks. A full platform modernization, such as replacing a legacy billing engine or rebuilding core infrastructure with AI and automation built in, usually runs 12 to 24 months. We deliver in phases with validation gates at each step, so your existing system keeps running and you see working results long before the final delivery.
