SQL-Ledger is a double entry accounting system. Accounting data is stored in an SQL Database Server and a standard web browser can be used as its user interface.

The entire system is linked through a chart of accounts. Each item in inventory is linked to income, expense, inventory and tax accounts. When items are sold and purchased the accounts are automatically updated.

The system uses the Perl language with a database interface module for processing and PostgreSQL for data storage.

Configuration files let you specify to which SQL database server to connect to, personal preferences such as company name, language, number and date format, etc.

 SQL-Ledger 3.0.6
