Just to add, if you no longer wish to use Business Policies in future then you can opt out but the existing policieswill still apply to any live listings until you edit them:
'What happens if I want to opt out of business policies?
You can opt out any time by selecting the Opt out link on the Manage business policies page. Your active listings won't be affected, but if you want to make changes to payment, shipping and returns terms, you’ll need to do that individually on each listing in future. You can also opt back in to business policies at any time; however your old policies will be deleted when you opt out. You will need to create new policies and associate your listings to them using a bulk editing tool if you opt back in.'
