I don't think that is quite right. The business plan is also a way to make sure that clubs don't get an unfair advantage from administration. Imagine a rich new owner takes over a club, buying them out of administration for a low price that pays creditors only 25p in the pound. Not many would think it fair if he then spent £50 million on new players - when he could, if he wanted, have used that £50m to pay creditors more of what they were owed. I think that's a key reason why EFL business plans last longer than a year.
