Even though the summary will be read first, it is easiest to write it last – providing an overview of the complete business plan. The aim is to draw the reader in, so what you include will depend on your audience. If you are seeking funding you need to really sell your business idea in the summary.
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.
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.
The planning process helps you learn about the different forces and factors that may affect your success. If you are already in business, it helps you to step back and look at what is working and what you can improve on. Instead of worrying about the future, a business plan helps to give you a sense of control over your business and your livelihood.
