Your financial perimeter
is fragmented

No single source of truth. Decisions delayed by days. Money leaking silently between PSPs, settlements, and banks — discovered only when a client complains.

Money disappears in process

Fees are opaque. Duplicates and stuck funds surface only through customer complaints — not your monitoring system.

Decisions delayed by 1–4 days

Detection takes 24–48 hours. Root cause analysis takes another 48. By then, the damage compounds.

👥

Scale requires hiring, not engineering

Transaction volume grows. Headcount grows with it. Critical knowledge lives in people, not in the system.

📊

Excel is not a financial OS

T+1 manual exports from 100+ PSP portals. No cross-provider visibility. No real-time control. No audit trail.

Six layers from event
to financial truth

An event-driven financial core with our immutable ledger at the center, Kafka at the input, and ClickHouse at the output. Every kopek — an explicit entry in an append-only journal.

01
Ingestion
Online events + batch PSP and bank statements streamed in real time

02
Normalization
Parser Factory maps all formats to canonical model. Enriches with PSP, fee, FX, and contract data

Matching
4-way engine: Exact → Fuzzy → Tolerance → AI → Human-in-the-loop

Exceptions
Auto-rules, HITL escalation, and continuous model training from every resolved case
Exception Layer

Reconciliation deviation types detected automatically

Settlement Gap

Money in bank, not in system

Possible leak or processing delay — flagged immediately for investigation

Orphan Transaction

System says money exists — it doesn't

Critical incident. Instant escalation with full transaction trace

Fee Leakage

Actual PSP fee exceeds contract

Auto-detection of deviation from your rate table. No more trusting PSP reports

Intelligence built
into the financial core

Every event published to the stream feeds the AI layer directly — no ETL, no latency, no data pipelines. Anomaly detection, routing optimization, and cash flow forecasting run on live data.

🔍

Anomaly Detection

Clustering on transaction patterns. Deviations from baseline route to exception queue before they become incidents

PSP Routing Optimization

Model ranks providers in real time by approval rate, fee, and latency. Route to the optimal PSP on every transaction

📈

30-Day Cash Flow Forecast

Seasonality, trends, and predictable rolling-reserve releases. Liquidity Ladder as a product — not a spreadsheet

🤖

AI Reconciliation Assistant

90%+ of routine analyst questions resolved by dashboards and an AI assistant trained on your ledger data

🧠

Self-Learning Matching Engine

Every HITL resolution becomes a training signal. The system improves its own match rate continuously — no manual rule updates

Liquidity Intelligence

Near real-time visibility of funds across PSPs and currencies. Detect idle funds, predict cash gaps, and control rolling reserve releases — before they affect operations.

30-day horizon
🔗

Full Transaction Trace

Any transaction — found, analysed, explained. Drill-down to the original PSP event in seconds. Root cause in minutes, not days. No black boxes in the financial perimeter.

Sub-minute RCA
🛡

Immutable Audit Trail

SHA-256 cryptographic chain on every entry. Retroactive modification is impossible. Every balance computed from the journal — never stored separately. Finance that cannot lie.

Tamper-proof
📡

Multi-PSP Normalisation

Parser Factory maps 100+ PSP report formats to a canonical data model. Add new providers without touching core logic. Batch and online sources unified in one stream.

100+ connectors
📐

Horizontal Scale

Multi-ledger architecture — isolated ledger per PSP and region. 50M tx/month target. Stateless services scale independently. Volume grows without growing the team or complexity.

50M tx/month

The ledger at the center
of everything

Our core is an operational ledger — not an accounting system, not an ERP. It handles the real-time movement of money with properties that enterprise finance has always needed but never had at the transaction level.

Atomicity

Either the full transaction is written or none of it. Debit always equals credit. No funds suspended between steps.

Immutability

Cryptographic SHA-256 chain. Each entry hashes the previous. Retroactive modification is structurally impossible.

Declarative Rules

Business posting rules readable by a finance professional — no developer required to modify them.

Bi-temporality

Correct retrospective reports and point-in-time queries. The system always knows what it knew and when.

Multi-ledger Isolation

Dedicated ledger per PSP. No hot accounts, no PostgreSQL contention, no shared-state failures.

Event Sourcing

Append-only journal as the single source of truth. Balances are computed — never stored, never drifted.

Not accounting.
Financial engineering.

↓ Lower

Fees & Hidden Costs

Calculate fees independently. Detect FX markups, routing losses, and settlement gaps that PSP reports obscure.

↓ Eliminated

Losses & Duplicates

Proactive detection of processing bugs before the customer complaint. Stuck funds surfaced in minutes.

↑ Faster

Time to Resolution

1–4 days of manual investigation → seconds to detect, minutes to root cause. With full AI-assisted context.

↑ Complete

Transparency

From management KPI to individual transaction in a few clicks. Near real-time drill-down with full traceability.

↑ Unlimited

Scale

Transaction volume grows. Team size does not. Matching rules and posting logic live in the architecture, not in people's heads.

↓ Reduced

Dependency on People

Institutional knowledge encoded in the system. Decision-making becomes reproducible, auditable, and transferable.

Deployed in your
infrastructure. Full stop.

Financial data of this scale and sensitivity never leaves your perimeter. NOR Engine is deployed entirely on your infrastructure — your cloud, your servers, your rules. We bring the architecture; you own every byte.

🔒

Zero data leaves your perimeter

NOR Engine is not a SaaS with shared tenancy. It is software you run. Transaction data, ledger state, reconciliation results — everything stays inside your Kubernetes cluster.

🏛

Your cloud or on-premise

AWS, GCP, Azure, or bare-metal datacenter — the stack is cloud-agnostic. Kubernetes-native deployment. No vendor lock-in to any managed service or external ledger provider.

Security-first cluster design

Financial perimeter isolated from other workloads. Network policies, secret management, and audit logging configured from day one — not retrofitted later.

📋

Audit-ready by design

Immutable event log, cryptographic chain, bi-temporal queries. Every access, every state change, every reconciliation decision is traceable and defensible to regulators.

🛡

Processing millions of euros daily — security is not a feature, it is the foundation

NOR Engine was designed from day one for the high-risk financial environment: 7 days a week, 24 hours a day, hundreds of PSPs, zero tolerance for data exposure.

NOR Engine feeds your
accounting layer —
not replaces it

Two ledgers, two responsibilities. NOR Engine handles real-time operational control. Your ERP — 1C, SAP, Oracle, or any other — handles statutory accounting. We produce the aggregates; your General Ledger receives them clean, reconciled, and ready.

Scheduled Export

Daily, hourly, or on-demand export in your ERP's native format — CSV, XML, JSON, or custom mapping. Configured once, runs automatically.

Custom Mapping

Chart of accounts, cost center assignment, inter-company elimination — all mapped to your specific ERP structure during onboarding.

From Excel + People
to Architecture + Automation

NOR Engine is purpose-built for high-volume, multi-PSP operators who need financial control at transaction level — in real time.
