How can I set the company field not to be a mandatory field
Even when I switch off in the order settings the company field not to be mandatory, it is in the cart check out a mandatory field. Maybe it is related to the VAT function.
I want to have the VAT and company field not mandatory, because only companies need to fill in the VAT number, private buyers don't need to fill in these fields.
Is this possible? 

If push comes to shove, you can always do this through a custom module using hook_form_alter() ... but it sounds like you might not be a developer?
