About Bigcapital

Bigcapital handles the core financial workflows a growing business needs: invoicing, expense tracking, bank reconciliation, and financial reporting. It replaces spreadsheets and disconnected tools with a single system that keeps your books in order without requiring an accounting degree to operate.

The software runs on Linux or any Docker-capable server. It integrates with Stripe for payment processing and supports multi-tenant deployments. Built with Node.js and React, Bigcapital offers a REST API for custom integrations and exports data to CSV or PDF for offline use.

This project is maintained by Bigcapital HQ under the AGPL-3.0 license. It is free to self-host, with optional cloud hosting available. Small teams or solo operators who want full control over their financial data without paying monthly per-seat fees will find it a practical alternative to proprietary SaaS accounting tools.
