For an online business, a detailed and in depth business plan is usually not necessary unless you are trying to combine your online business with a traditional business. For most online business startups, the detail involved with planning a traditional business is not required. However, it would still be beneficial to you if most of the topics were still covered, even if only briefly. Having a written plan in front of you will help you to focus on important aspects of the business.
A business plan can be used as a vehicle for accurate communication among principals, managers, staff, and outside sources of capital. It will also help to identify, isolate, and solve problems in your structure, operations, and/or finances. Along with these advantages, a business plan captures a view of the big picture, which makes a company better prepared to take advantage of opportunities for improvement and/or handle crises.
