Hello people I hope everybody is staying safe! I wanted to use Odoo's open source community version as the back-end base for a POS system I'm building. After comparing the community vs enterprise edition (https://www.odoo.com/page/editions) I noticed there are quite a few features that aren't included in the open-source system.
I was under the impression that Odoo was a true open-source system that didn't limit its functions, so can those features be enabled/added manually after installing the free version with some knowhow and tinkering, or are those features not available at all without paying?
Thank you very much for your help!
