Enterprise Engineering for Operational Industries
Nexos delivers enterprise software for businesses that operate physical infrastructure: fuel networks, retail chains, hotels, and industrial sites. We connect devices, dispensers, POS terminals, tank gauges, and charge points, to centralised platforms that give management real time visibility and control.
In our markets, precision is a commercial requirement: a fiscal error is a compliance incident, a booking error is a lost guest, and downtime is measurable revenue loss. We engineer accordingly, with rigorous testing, monitored releases, and audit ready records.
The Vision
To be the engineering partner operational businesses rely on, a single team able to take a system from physical device to cloud platform, and keep it running for years.
The Philosophy
Security first, data integrity always. Every system we ship is built on the assumption that it will be audited, attacked, and depended upon, and must withstand all three.
Software and Hardware Expertise in One Team
Nexos combines disciplines that rarely sit in one team: device and hardware integration, back end platform engineering, fiscal and regulatory compliance, applied AI, and security. That combination lets us deliver complete systems without hand offs between vendors.
We work with the systems businesses already run, legacy POS, existing property management, established ERP, and modernise around them with minimal disruption, clear migration paths, and no forced rewrites.

Core Values
Compliance
Every system meets the regulations that apply to it: Bulgarian NRA fiscal rules (Ordinance H 18, SUPTO), GDPR, PCI DSS payment standards, and NIS2 security requirements, implemented and documented as part of delivery.
Uptime
Mission critical means zero tolerance for downtime. Our systems are engineered for 99.99% availability with automated failover and real time monitoring.
Innovation
We apply AI, predictive analytics, and modern cloud architecture where they produce measurable results, forecasting, anomaly detection, dynamic pricing, not where they merely decorate a slide.
Full Stack Engineering Meets Industrial Integration
Systems Analysis & Hardware Mapping
A complete audit of your physical and software estate, devices, integrations, data flows, and compliance posture, resulting in a concrete technical roadmap.
Backend Architecture & API Design
Real time data pipelines, compliance engines, and secure APIs, designed for scale and auditability.
Frontend Command Centers
Deploying operational dashboards and PWAs that turn complex data into clear, actionable intelligence.
Security Hardening & Managed Operations
Hardened, monitored 24/7, and scaled as operations grow, fully managed by our team.
Commitment to Excellence
Every delivered system reflects the same standard: engineered by senior professionals, documented, monitored, and supported. If it carries our name, it is built to operate.
