About LedgerFlow

Who We Are

LedgerFlow is a Cape Town-based fintech company specialising in enterprise-grade ledger management and financial transaction processing systems. Founded by experienced technology executives with decades of combined expertise in financial technology and enterprise software, LedgerFlow was built to address the fundamental challenge facing modern payment service providers: traditional transaction systems simply cannot keep pace with the complexity, volume, and regulatory demands of today's financial landscape.

We provide payment service providers (PSPs), financial institutions, and merchants with a robust, real-time financial data integrity platform that delivers the controls, auditability, and scalability required for sophisticated fund management operations.

What We Do

LedgerFlow delivers a comprehensive, self-contained enterprise accounting platform built entirely on modern, open-source infrastructure. Our platform implements:

• Double-Entry Bookkeeping with automatic debit/credit normalisation across all account types
• Multi-Currency Transaction Processing with integrated forex conversion and revenue margin management
• Real-Time Fraud Detection using proprietary cyclic trigonometric behavioural analysis
• Maker-Checker (4-Eye) Approval Workflows with strict role separation enforced at the database level
• Automated Reconciliation with configurable CSV matching templates and exception workflows
• Service Rating and Billing with a configurable rule-based engine
• Customer and KYC Management with document attestation and expiry tracking
• Comprehensive Audit Logging capturing every change with full JSON before/after diffs
• Role-Based Access Control with 25+ granular permission categories

The platform is delivered as a containerised application of 17 orchestrated services, backed by PostgreSQL 18 with proprietary extensions — supporting over 300 billion unique transactions and designed from the ground up for high-throughput, low-latency financial operations.

Our Technology Philosophy

We believe that the database should be the source of truth — and the engine of business logic. LedgerFlow's architecture reflects this conviction: business rules, fraud detection algorithms, audit mechanisms, and workflow controls are implemented at the database layer, ensuring consistency and integrity regardless of which application or API surface accesses the data.

Our proprietary algorithms — including cyclic fraud detection using trigonometric circular statistics and automatic transaction amount normalisation by account type — represent years of applied research and production refinement in the payment processing domain.

We use PostgreSQL as a full infrastructure platform, replacing external message brokers with pgmq, external schedulers with pg_timetable, and maintaining a complete observability stack (Grafana, Prometheus, Loki, Tempo, Pyroscope) for production-grade monitoring.

Our Mission

LedgerFlow exists to give financial institutions and payment service providers the infrastructure they need to operate with integrity, precision, and confidence. We combine deep domain expertise in financial operations with modern software engineering to deliver a platform that is not just functionally complete, but architecturally sound — built to scale, built to audit, and built to last.

We are committed to:

• Operational Excellence — rigorous engineering standards, comprehensive testing, and production-proven reliability
• Transparency — complete audit trails, open API specifications, and clear documentation of all platform behaviour
• Innovation — continuous investment in proprietary algorithms, observability, and developer experience
• Partnership — working closely with our Customers to understand their operational needs and regulatory environments
