Axiomatic Documentation

Multi-book, event-sourced accounting infrastructure with automated posting, field-level encryption, and a complete REST API.

Event-Sourced Ledger

Financial activities are recorded as immutable events, then automatically posted to the general ledger via a DSL rule engine.

Multi-Book Accounting

Run GAAP, IFRS, tax, and management books in parallel from the same event stream. Each book can have its own rule pack.

AR / AP Engine

Full invoicing and bill management with aging reports, payment tracking, and automatic ledger posting on every payment.

Field-Level Encryption

All financial data is encrypted at rest with AES-256-GCM using a two-layer key hierarchy (KEK + per-entity DEK).

REST API

Complete REST API with interactive documentation. Create entities, post events, query reports, and manage the full lifecycle.

Multi-Currency & FX

Native multi-currency support with automatic rate lookup, triangulation, and period-end revaluation adjustments.
