One of the primary reasons new businesses fail is they simply don’t have enough money. Sure, sometimes they just have a terrible business idea (mittens for cats was not the hole in the market you envisioned). But usually it’s money, and a great business plan – written thoughtfully and early – will reveal potential money problems (and probably the mittens problem too). But people often think of a business plan as a document to provide to a lender or an investor to solicit cash. And that’s certainly true. But even if you don’t need money, you still need a plan.
