BookFunnel doesn’t support Word Docs, but we know that many authors have their books in this format. To convert a Word Doc into the EPUB and MOBI files that BookFunnel needs, we recommend a service called Draft2Digital.
Though Draft2Digital is actually an ebook distributor, they also happen to have a really topnotch Word Doc converter. You can upload your Doc and have them convert it into the EPUB and MOBI files you need without having to distribute through their service. Though, they are a pretty great service, and they can distribute your books to many stores you may not be able to reach on your own.
We are not affiliated with D2D, but we think they provide an excellent service.
