I feel it is difficult to get simple answers regarding Odoo, before purchasing. 

My earlier query was straight forward, yet no-one appears to know the answer (I was told Odoo staff frequent these forums). Surely I would not be the first user planning to use this in a service environment and having the need to make notes for each job/invoice. 

Sales are keen to get me to sign up, and even have me sell/recommend to other users, but I need to determine if Odoo will do what I need before any of that happens. 'The horse has to come before the cart'.

To post example images here to make what I am seeking clearer, requires Karma points - seems like stupidity. It should not be a privilege to post images on a support forum.
