Odoo has a very powerful framework, and tons of things can be achieved just by using/activating options or by following specific patterns. Consequently, if you run into some technical issues or if you are not sure about some complex cases, then you can post your query on Odoo's official help forum. Lots of developers are active on this forum, including some official Odoo employees.
