LedgerSMB is an open-source web-based accounting and ERP system for small to medium businesses. Descended from SQL-Ledger, it provides double-entry accounting, accounts payable and receivable, inventory, fixed assets and more, with a strong emphasis on correctness, audit trails and extensibility.

Key Features

• Double-entry accounting — Rigorous general ledger with chart of accounts and full audit trail.
• Accounts payable & receivable — Invoicing, payments, receipts and aging reports.
• Inventory — Stock items, parts, services and warehouse management.
• Fixed assets — Asset registers with depreciation schedules.
• Multi-language & multi-currency — Built for international use with localisation support.
• Web-based — Runs in the browser, no client software to install.
• Scripting & extensibility — Customisable via stored procedures and a plugin architecture.
• Correct-by-design — Emphasis on accounting accuracy and data integrity.

Why Use LedgerSMB?

LedgerSMB suits businesses that need a dependable, auditable accounting core rather than a sprawling feature set. Its double-entry foundation and clean bookkeeping workflows make it a strong choice for finance-first organisations.

Use Cases

• SMBs needing solid AR/AP, invoicing and general ledger.
• Accountants and bookkeepers working with a clean audit trail.
• Organisations migrating from legacy accounting systems to open source.
