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.
Taking the time out of your business to plan will give you a sense of control about the future of your business and pay off in the long run! Business planning can seem overwhelming and time-consuming, but many successful businesses look at it as an opportunity.
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.
At its core, a business plan helps you prove to yourself and others whether or not your business idea is worth pursuing. It’s the best way to take a step back, look at your idea holistically, and solve for issues years down the road before you start getting into the weeds.
