There aren't any hard guidelines for a WCSH business plan, so as long as your approach is reasonable, it should be fine. It has to detail the way capital will be spent and a timeline for spending it; we usually advise clients to go quarter-by-quarter. But there's no specific template, no IRS form, nothing concrete to tell you how it needs to look and how it needs to be organized. I'd at least run your draft by counsel, though.
