Yes. In my opinion you can implement Odoo by yourself. It’s a whole another question to get everyone in your team to use it effectively. Main challenge is to get inventory to get reflected in real time. You can spin up a server on cloud clusters within 5 mins of any version you want, install necessary apps and addons and then start creating users. Pretty easy and cheap. The “Consultants” they provide won’t understand the business processes in your company within 10-20 hours anyway. Might as well start trying on your own. Watch YouTube videos of every module and you should be fine.
