The question becomes, will there be one and only one other company with only one address forever and ever until the end of time? If not, you probably want to store a foreign key rather than "1."
I know one person companies who have more than one shipping address. I work on enterprise software that prepends a company identifier to most everything.
I also know companies that try to fix things themselves, then ship it out if they can't. I also know a company that has mobile mechanics they send to people who've screwed up trying to fix their cars... so, it depends. See Mark's answer.
