An open source accounting and inventory system for small and medium businesses to automate bookkeeping and financial reporting.

Bigcapital is an open-source, self-hosted web app and server for accounting and CRM. It provides a web-based platform designed for small and medium businesses to manage bookkeeping, track inventory, and automate recurring accounting processes. The software serves as a centralized hub for business finances, allowing organizations to maintain a digital ledger of all financial activities.
The software is deployed as a server-side application. Users can host the platform on their own private infrastructure using Docker and Docker Compose, which ensures that sensitive financial data remains under the control of the business owner. For those requiring a customized setup, the project provides guides for local installation and supports development environments like Gitpod to facilitate configuration and modification of the source code.
Bigcapital is built for businesses that require a structured method to organize transactions and generate intelligent financial reports to inform strategic decision making. The architecture includes a headless mode, which allows developers to integrate the core accounting engine into other existing software systems through an API. This functionality is particularly useful for companies that have their own front-end interfaces but need a reliable back-end to handle the complexities of double-entry bookkeeping. By utilizing this API, businesses can automate the flow of data from sales or payment platforms directly into their financial records.
It serves as a self-managed financial planning and analysis tool for organizations seeking an open-source accounting suite.
