When developing any business plan you should always keep in mind your intended audience - in other words, your reader and/or potential investor. Consider reading your plan from the point of view of these three main groups:
By providing cash, investors will own shares in your company. Only if they are a small subset with non financial goals in the company will they be interested in the return instead of the investment into the future. Just showing the company giving huge dividends to investors is not the right route to take. Paying out dividends means the company's means are reduced and investors want increased value leading to strategic sales and more investing. The type of investor your company will get is based on the growth plans and the returns through dividends and appreciation.
Lenders just want to see the balance sheet and cash flow statement. The balance sheet shows them the assets in the company in upcoming years which the lender can hold as collateral and sell in the event of loan default. The cash flow statement shows you can start to build an overall cash flow fast after launch and repay the principal and interest on the loan. The whole plan hinges on having a good market opportunity, the right marketing operations and a management team that can come through.
Partners for your business can come from individuals and other companies. You may need to show them your business plan as proof of your intentions in the pre-launch phase. They will want to learn about both your product (or service) and the operations and marketing methods you wish to execute, to see whether or not they will meld with their own current business practices
