Clarity for complex transactions with our intelligent billing solutions.
Major European operators process hundreds of thousands of euros daily through billing platforms architected by DNA Solutions. Deloitte audits confirmed transaction accuracy and financial controls where revenue leakage has immediate impact. Event-driven processing ensures no transaction loss, microservices enable independent scaling, and comprehensive monitoring detects anomalies before they affect revenue.
Banking modernization without gambling on stability.
Financial infrastructure modernization demands maintaining compliance throughout migration while supporting growing transaction volumes. Zero-downtime requires phased approaches validating changes before production cutover. Regulatory constraints discovered during assessment shape architecture, not surprised mid-implementation.
Microservices enable independent component updates without system-wide deployments. AWS and Azure infrastructure optimizes costs from inception. Security and compliance build into architecture, not retrofitted. Complete documentation and training transfer banking system ownership. Modernization creating capability, not permanent consulting dependency.

What financial institutions ask about banking software development
Electronic toll collection systems require major infrastructure investment and carry high operational risk. DNA Solutions provides clear, practical answers to the real questions toll operators.
We built billing platforms processing hundreds of thousands of euros daily. Deloitte audits validated what matters: accuracy when errors mean real losses.
Production experience taught us where financial systems actually break. Surge loads exposing architecture weaknesses. Data loss from poor event handling. Scaling nightmares from monolithic design. Revenue leaking through monitoring gaps. Fraud patterns invisible to manual review.
Maintaining systems where downtime stops revenue shaped how we build. Phased rollouts catching problems early. Compliance designed in from day one, not bolted on later. Security protecting financial data properly. Monitoring showing health before failures cascade.
We communicate honestly when complexity emerges. Timeline adjustments beat rushed mistakes. Complete knowledge transfer means your teams own systems, not depend on us forever. Partnership beyond launch, not handoff and disappear.
AI catches patterns humans and rules miss. Machine learning models analyze millions of transactions revealing subtle fraud indicators. Behavioral analysis spots account takeovers through login timing, device changes, transaction patterns. Real-time scoring blocks suspicious activity during authorization, not after settlement.
Traditional rule-based detection creates two problems: excessive false positives burying analysts, or tuned-down sensitivity missing sophisticated attacks. Machine learning adapts continuously, learning from new fraud cases and evolving customer behavior. Network analysis reveals coordinated rings operating across accounts.
Implementation reality: clean training data matters more than fancy algorithms. Infrastructure must score transactions in milliseconds. Model monitoring catches accuracy drift before fraud increases. Integration with core banking enables instant blocking.
Production deployment separates proofs-of-concept from operational prevention. Documentation enables internal teams maintaining systems as threats evolve.
Migration demands maintaining compliance and operations throughout. Assessment reveals actual complexity: hidden dependencies, data quality problems, integration nightmares, regulatory constraints shaping strategy.
Phased approaches migrate functionality incrementally. Parallel infrastructure runs new and legacy simultaneously, comparing outputs proving equivalence. Data migration handles decades of transactions, customer records, configuration. Integration adapters connect during transition.
Zero-downtime requires database replication maintaining synchronization. Gradual traffic shifting between systems. Rollback procedures ensuring continuity if problems emerge. Comprehensive testing validating workflows before cutover.
Timeline depends on legacy complexity, regulatory requirements, data quality, organizational readiness. Realistic estimates account for discovered integration challenges, compliance validation, staff training. Transparency about complexity prevents rushed decisions compromising quality.
PEPPOL provides standardized e-invoicing infrastructure across Europe. Financial institutions integrate with PEPPOL access points (Mercurius in Belgium) sending and receiving structured invoices in UBL format.
Integration connects banking systems to access points through secure APIs. Internal invoice formats transform to UBL standard. Message validation ensures PEPPOL compliance. Document routing through network to trading partners. Access point handles delivery, confirmation, compliance monitoring.
Benefits: regulatory compliance with evolving EU mandates. Automated processing eliminating manual data entry. Faster payment cycles through electronic workflows. Improved audit trails through standardized documentation.
PEPPOL adoption accelerates across European public and private sectors. Integration becomes increasingly necessary for financial institutions serving business clients.
Timeline depends on existing system complexity and trading partner volume requiring connectivity.
