LedgerSMB

Project570

Self-hosted, web-based double-entry accounting and ERP for small and medium businesses.

What you can build

  • Map a supplier invoice CSV into LedgerSMB fields and report invalid account codes, dates, or tax values before import.
  • Read LedgerSMB customer balances and payment records and produce an aging report grouped by overdue interval.
  • Compare LedgerSMB journal exports with account totals and flag entries whose debits and credits do not reconcile.
  • Compare LedgerSMB purchase orders with received quantities and supplier invoices, then list unmatched line items.
  • Apply proposed prices and costs to LedgerSMB quotation lines and calculate margin scenarios before staff issue the quote.

Try this prompt

Build a small, separate quotation margin review tool for LedgerSMB users. Let a user enter quotation line descriptions, quantities, unit costs, and proposed unit prices; calculate line and total margins and export a clearly labeled CSV for review before manual entry in LedgerSMB. Validate numeric inputs and include a sample file. Preserve entered data between sessions. Do not connect to LedgerSMB, assume an undocumented API, or present the calculations as accounting records.

Get started

  1. Check server requirements

    For the README's current development version, prepare Perl 5.38 or later and PostgreSQL 14 or later. A web server is required for production installs.

  2. Review the evaluation setup

    The README's Quick start links Docker and docker-compose requirements and the official ledgersmb-docker compose file for version 1.13. The documented setup is for evaluation, not production.

  3. Prepare first use

    After setup, use the setup page for company databases and the login page for normal access. Follow the linked preparation-for-first-use guide; the evaluation setup lacks secure connections to protect passwords.

License & notes

GPL-2.0-onlyLedgerSMB is GPL-2.0-only and can be used commercially. When distributing modified or derivative versions, GPLv2 obligations apply, including required notices and source availability under the license. Merely running it internally does not by itself require publishing source. Hosting, PostgreSQL operations, backups, and any email service have separate costs; no dollar amounts are provided.

  • Requires self-hosting and PostgreSQL; production deployment needs secure connections and operational maintenance.
  • The README's Docker compose instructions are explicitly evaluation-only and refer to version 1.13, while its system requirements describe version 1.14 development.
  • GPL-2.0-only obligations apply when distributing modified or derivative works; review the license before bundling or redistributing adaptations.
  • The supplied evidence does not document specific bank-feed integrations, local tax compliance, or a hosted service.
