That doesn’t mean you have to bust out Word and start the plan from scratch. A template is great--you probably aren’t doing anything that hasn’t been done before, so it provides a proven structure for your plan. Pretty much everything on it can be customized.
A business plan is not a document you create once and store in your bottom drawer. It is a living guide that you should develop as your business grows and changes. Successful businesses review and update their business plan when circumstances change.
Set yourself a reminder to review your business plan regularly. If you have a team in your business, holding brainstorming sessions is a good way to benefit from their knowledge - it ensures you are all on the same page and that you get their support.
While every business owner should have an ongoing planning process to help them run their business, not every business owner needs a complete, formal business plan suitable for submitting to a potential investor, or bank, or venture capital contest. So don’t include outline points just because they are on a big list somewhere, or on this list, unless you’re developing a standard business plan that you’ll be showing to someone who expects to see a standard business plan.
