ERPNext is a fully open-source ERP built on the Frappe framework. It handles accounting, sales, purchasing, inventory, manufacturing, projects, and HR, and it's remarkably easy to extend.
ERPNext is our longest-running practice: we've used it to run print shops, timber-frame production, shipping operations, and our own business.

Custom ERPNext functions get automated test suites, so updates and new features don't break production.
We build with the grain of the Frappe framework, which keeps upgrades smooth and makes the code familiar to any Frappe developer.
With frappe-nix, every bench is declared in code and built the same way in development, testing, and production.
We run ERPNext on our managed NixOS platform, or on a production server in your own building when that's what the work requires.
