In addition to a performance tool, perfect business plan should contain other necessary tools in its system, which really make it a perfect plan. It must have a human resource tool, a marketing and strategy tool, financial tool, communication tool, and most importantly, an investor's guide. A well-defined business plan attracts others to be part of the vision. It has to have a well-defined goal and objective that will set the stage to bring others into the business. It should inspire teamwork and creativity among its people and ensures everyone understands the goals and objectives.
On the subject of finance, you need to produce realistic financial details. How much money will the business require? What are the expenses required? How much tax will you need to pay? What are the profit margins? Do you stand a good chance of achieving these sums, and how? Finance plans should include income statements, cash-flow statements, balance sheets and profit analysis. This should form a big part of your business plan, in order to convince the vendor or bank manager of your credibility.
