Mission critical software for
Fuel Retail
We engineer the tissue between physical infrastructure and digital intelligence: forecourt controllers, fiscal devices, real time dashboards, and applied AI operators actually trust.
Explore CapabilitiesA senior team that ships systems regulated industries can stake their operations on from the forecourt to the cloud, in one continuous delivery path.
Real time by default
Event driven pipelines carrying forecourt, fiscal, and industrial telemetry at sub second latency alarms never lose a race with the next polling cycle.
Compliance as code
Every system ships with Bulgarian NRA fiscal rules, GDPR, PSD2, and NIS2 baked into the build pipeline not bolted on at audit time.
Hardware to cloud, one team
Dispenser controllers, ATG probes, payment terminals, MQTT brokers, cloud ingestion, dashboards delivered by the same engineers who will be on the phone at 3 AM.
Operational intelligence
Applied AI where it actually pays back: demand forecasting for fuel chains, anomaly detection on pump flow, predictive maintenance on industrial lines, receipt level fraud scoring.
Engineered for operators, not pitch decks
GNXSoft is a Bulgarian enterprise software company specialising in the systems that keep regulated, physical industries running: fuel retail, cash register ecosystems under the NRA fiscal regime, industrial IoT, and applied AI. We are small on purpose a senior engineering team that ships from requirements to production without a layer of account management between you and the code.
Enterprise-Grade Solutions
Scalable architecture built for growth and reliability.
Dedicated Partnership
Operating as an extension of your team, not just a vendor.
Proven Track Record
Trusted by businesses across industries to deliver on time.
Core capabilities
Six practices that cover the stack we ship most often: fuel & IoT, fiscal & POS, custom software, applied AI, cyber security, and cloud operations.
Industrial IoT & Fuel Station Automation
End to end automation for fuel retail and distributed industrial sites: dispenser controllers, ATG probes, price pole integration, event driven SCADA, and cellular tolerant cloud ingest.
Learn moreFiscal Devices, POS & Cash Register Integration
Bulgarian NRA fiscal compliance delivered as engineered software: SUPTO conformant POS, near real time transmission, signed firmware manifests, and duplicate safe retries for sites with flaky connectivity.
Learn moreCustom Software Development
Custom software built by senior engineers: scalable Python/Django backends, real time APIs, React and operator grade dashboards, and the migrations to get you there from whatever you run today.
Learn moreApplied AI & Machine Learning
Applied AI where the ROI is provable: demand forecasting for fuel networks, anomaly detection on dispenser flow, predictive maintenance on industrial assets, receipt level fraud scoring, and operator copilots grounded in your own data.
Learn moreCyber Security & Compliance
Security services built around regulated, physical systems: penetration testing against OT/IT boundaries, NIS2 readiness, payment path PCI audits, continuous threat monitoring, and incident response with a four hour SLA.
Learn moreInfrastructure & Cloud Operations
Managed operations on AWS, Azure, GCP, and on premise: infrastructure as code, Kubernetes, 24/7 observability, tested disaster recovery, and a concrete path off the platform if you ever need to leave.
