What percentage of business conducted in home office do I use if the "home office" I am accounting for is the room in which supplies are stored 100% of the time?

I store all supplies and goods here 100% of the time.  I conduct business in my living room (when placing orders), over the phone, and when I deliver them.  All orders and products are stored in "home office", though.

If you are using the space 100% of the time for business, then 100% of your business incomes from that "home office."
