A business plan is a decisive factor for your success. It can range from 10 pages to 30+ pages. It always depends on the purpose of the business plan. Do you need a business plan just for yourself so that you can evaluate your idea? Need one for the JobCenter to start your self-employment. Or do you need a business plan for an investor so that you get seed capital. It may also be that you need a business plan for a limited project.
I’ll tell you how to decide for what purpose you need a plan, what the benefits are and what the business plan requirements are.
