System requirements

Note that these are the system requirements for LedgerSMB 1.11.0-dev, the current development version. Please check the system requirements for the 1.10 stable version and the 1.9 'old stable' version.


  • Perl 5.32+
  • PostgreSQL 13+
  • Web server (e.g. nginx, Apache, lighttpd, Varnish)

The web server is only required for production installs; for evaluation purposes a simpler setup can be used, as detailed below.

Quick start

For from-tarball installation instructions, see


This instruction assumes you have Docker installed as well as docker-compose.

 $ wget
 $ docker-compose up -d

This creates both the LedgerSMB image and a database image with a persistent database. Note that this setup is not sufficient for production purposes because it lacks secure connections to protect your users' passwords.

Next steps

The system is installed and should be available for evaluation through

  • http://localhost:5762/
    Creation and privileged management of company databases
  • http://localhost:5762/
    Normal login for the application

The system is ready for preparation for first use.

NOTE: This setup does not use a webserver like nginx or Apache. Setups which do include one will yield a faster user experience due to (much) faster page load times and web request responses. For production setups, please consider adding a webserver to the installation.
