A well-thought-out business plan serves as a guide for launching and managing your business and choosing its legal structure. When you go through the steps of how to write a business plan, you'll be able to see more clearly what legal structure you'll need for your endeavor.
Traditional business plans use a standard structure and offer details on each aspect of the business. A lean startup business plan uses the same structure but summarizes the key elements.
Depending on your type of business and the structure you choose, you may need to apply for a business registration number. You will use this number to file taxes, open up a bank account, and conduct other official business.
