High-performance accounting infrastructure
AsyncLedger

A fast, self-hosted ledger for modern financial systems.

AsyncLedger is a highly performant accounts ledger built on double-entry accounting, efficient account nesting and flexible metadata. It gives software teams a reliable foundation for balances, reconciliation and financial records while keeping data under their control.

Account balances can be reconciled efficiently using the nested account model, metadata filters and structured journal history.

01

Double-entry core

Record balanced journal entries with clear debit and credit movement across accounts.

02

Nested accounts

Use efficient account hierarchy to model complex balances without losing structure.

03

Flexible metadata

Attach tags and metadata to support reporting, filtering and custom integrations.

04

Self-hosted

Run the ledger in your own environment so your financial data remains yours.

Architecture

Ledger infrastructure designed for custom software.

AsyncLedger is built for teams that need accounting-grade records inside their own applications. It provides the ledger foundation while leaving product design, workflows and integration logic under your control.

Account nesting system

Model parent and child accounts efficiently, making it easier to group, query and reconcile balances across account hierarchies.

Efficient reconciliation

Compare expected and actual balances using structured entries, account hierarchy, tags and metadata-driven filters.

Data ownership

Self-host AsyncLedger in your own infrastructure. Your ledger records, balances and financial history stay under your control.

Optional browsing UI

Use the built-in interface to browse accounts, inspect entries and review ledger activity when a UI is useful.

Reconciliation

Designed to make balances easier to verify.

AsyncLedger keeps journal entries structured, account relationships clear and metadata available for precise filtering. That makes it easier to reconcile balances across accounts, customers, products, regions or any custom dimension your software requires.

Post balanced entries

Record transactions using double-entry accounting so every movement has a corresponding balancing entry.

Query nested balances

Resolve balances at specific account levels or across grouped account branches.

Filter by context

Use metadata and tags to reconcile by customer, system, period, product or custom business rules.

Integration

Built to sit inside your software stack.

AsyncLedger is designed for custom applications that need reliable financial records without forcing teams into a fixed accounting product model.

Metadata-first records

Attach structured metadata to entries so your application can preserve business context.

Tag-based organisation

Add flexible tags for grouping, reporting, filtering and reconciliation workflows.

Optional UI layer

Use the built-in interface when teams need to browse accounts and inspect ledger activity.

Self-hosted deployment

Deploy AsyncLedger in your own environment and keep operational control over your data.

Developer experience

Pre-made wrappers for common engineering stacks.

Integrate AsyncLedger into your application using ready-made wrappers for Go, Rust, Python and TypeScript.

Go

Use AsyncLedger in high-throughput backend services and internal platforms.

Rust

Integrate with systems that need strong performance and predictable behaviour.

Python

Connect ledger workflows to data pipelines, operations tooling and automation.

TypeScript

Use cases

For products that need reliable ledger behaviour.

Financial platforms

Power balances, transfers, customer funds and internal financial records.

SaaS billing systems

Track credits, debits, adjustments, usage and deferred balances.

Marketplaces

Manage account movement across buyers, sellers, fees and settlement flows.

Internal systems

Add structured ledger records to operational software and back-office tools.

Control

Your infrastructure. Your records. Your data.

AsyncLedger is not a closed accounting platform. It is ledger infrastructure for teams that want financial record keeping inside their own software environment.
