LedgerSMB is an open source, cross-platform and web-based application, a double-entry accounting system that offers a wide range of features. It’s a high quality software that can be easily described as secure, performant, usable, and accessible. It is inspired by the SQL-Ledger software and runs on both GNU/Linux and Microsoft Windows operating systems.

Key features include sales, budgeting, invoicing, accounts payable, accounts receivable, purchasing, general ledger, inventory management, as well as a flexible framework, which supports RAD (Rapid Application Development) for custom extensions, recurring transactions, financial reports, POS (Point of Sale) system, time tracking, project accounting, inventory tracking, quotation and order management, as well as support for multiple currencies.

LedgerSMB supports a wide range of modern web browsers, including Mozilla Firefox, Google Chrome, Chromium, Opera, Internet Explorer, Safari, and others. As its name suggests, it is designed for small and medium-sized businesses that want to handle small and medium transaction volumes daily. However, LedgerSMB is capable of handling thousands of accounts payable and accounts receivable transactions per week.

The software can be easily extended through plugins (extensions), which are developed by members of the LedgerSMB community and can be downloaded from the project’s website. These include a plugin that allows users to import transactions from CSV files, a budgeting add-on that allows you to track budgets by department or project and execute variance reports, as well as an extension to create template transactions.

As mentioned, LedgerSMB is a web-based application, which means that it can be used on any operating system that has a decent and supported web browser (see below for details). Officially tested platforms include GNU/Linux and Microsoft Windows. Both 64-bit and 32-bit hardware platforms are supported at this time.
