A couple of colleagues and I have recently been looking at Odoo, there is an open source version which you can self host. There didn’t seem to be any recent Vagrant based versions of this, so I’ve put one together which you can clone from:
git clone https://github.com/ssx/vagrant-odoo
It’ll then get the latest install script, run it and get the environment set up. Theres more information in the readme.md file within the repo as well.
