Small correction to the above info: no need to incorporate for the App Stores.
We are a family business (not incorporated) but we are on all the App Stores (Apple, Amazon, Google, Nook, Microsoft) as a company, because they do see the partnership as company as long as you have a registered business name.
Behind the scenes I’m the one that has registered the business name and fetched the ITIN from the IRS so to get an EIN as DFT Games. Bottom line, we have all the benefits of a company but none of the incorporation hassles (anyhow we’ll incorporate this year to reduce the tax burden).
Did you have to get a D.U.N.S. number? Seems to be a requirement for the App Store (though I’d be happy to hear otherwise) and the D.U.N.S. number is for separate legal entities. Not sure if a partnership is a separate legal entity. We’ve registered the business name as a partnership but the D.U.N.S. is still a no-go AFAIK.
