Everything you need

A complete double-entry ledger engine, purpose-built for platforms that move money.

Double-Entry Engine

Strict balance enforcement at the transaction level. Every posting must balance.

Multi-Currency

Unified registry for fiat (ISO 4217), crypto (ISO 24165), stablecoins, and commodities.

Real-Time Reports

Trial balance, P&L, and balance sheet generated in milliseconds.

Tamper-Evident Audit

SHA-256 hash chain across all journal entries. Detect any tampering instantly.

API-First Design

RESTful API with OpenAPI spec. Integrate in hours, not months.

Config-Driven Rules

Add new transaction types through API configuration. Zero code changes.

How it works

Get from zero to production-grade accounting in three steps.

1

Create your account

Sign up free, generate an API key, and connect your platform in minutes.

2

Post financial events

Send transaction data via REST API. GL System handles the double-entry accounting.

3

Query & report

Generate trial balances, P&L, and balance sheets. Export in CSV, PDF, or Excel.

See it in action

Post a financial event with a single API call. GL System creates the journal entries, updates balances, and extends the hash chain automatically.

  • Idempotent event ingestion with unique event keys
  • Automatic double-entry posting from config-driven rules
  • Real-time balance updates across all affected accounts
  • SHA-256 hash chain extended with every journal entry
