Hi I found out that my company system has an upgraded version of the Timesheets module. A page pops up after clicking "Upgrade" button. However, when I choose the Timesheets module for upgrade, the price shows zero. I'm confused and need some advice.
1. Is it free? As stated "Those apps are free as long as you don't need more apps for hosting options."
2. My company's Odoo version is not a hosted version (no cloud connection), is it free to use/upgrade?
3. My company's Odoo is version 12, is it free to use/upgrade?
Thanks in advance
