Overview

BigCapital is an open-source accounting platform for small and medium businesses, combining accounting, inventory, invoicing, bills, expenses, and financial reporting. It also exposes a Headless Accounting API and can be self-hosted with Docker. The latest release checked on September 17, 2026 is v0.25.40.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Combine double-entry accounting, invoicing, bills, inventory, and financial reports

Business transactions flow into a double-entry accounting model so invoices, bills, expenses, and inventory can feed financial statements and reports from one system.

Sources: [2][4]

Use the platform as a Headless Accounting API behind existing systems

The README explicitly describes an API-based Headless Accounting use case for organizing external transactions in a double-entry system and producing financial reports.

Sources: [2]

For teams that want QuickBooks- or Xero-style accounting under their own control

It is especially relevant when accounting and inventory should live together and existing applications need API-level integration.

Sources: [1][2]

Production is a multi-service stack that needs secrets, backups, and upgrade planning

The production Compose includes the web app and server plus MariaDB, Redis, Garage, Gotenberg, ClickHouse, and a proxy. v0.25.40 added ClickHouse to the production Compose. Treat database and object-storage backup, secret management, and upgrade testing as production requirements.
