Will You Roll Your Eyes?
I'm asked often how long a business plan ought to be? Obviously the answer depends on several points, for example look at your products/service - how complicated are they?
A business plan is vital to the growth and progression of a business. Your business plan is your roadmap. The path to your success, it outlines your mission or vision, it defines your strategy.
When putting one together for investors or lenders, a version of your plan with more details is warranted; charts, projections, etc.
Having a business plan is critical to the success of small businesses, if you need to start by jotting down notes on a napkin, start there but do yourself a favor and do have a plan.
