Since this will be your first year of business for the ice cream and nut shop I would do two things. First, follow the advice Clough mentioned. Second, for your first year do a very detailed break even analysis and adjust every month or every quarter based on year to date sales. You also need to adjust your forecasted numbers from the incomes statement, balance sheet, and cashflow statement. While a vision is good, you need to be sure you are realistic. I don't know how you are financing your business, but if it was leveraged through a bank (which I'm assuming it was) you need to be very detailed on your cashflow statements because that will be your most difficult thing to manage with the purchase of a new building. If you paid for it or there was some private equity cash injection (which I am assuming it was not) you still need to do those things but there is a little less pressure.
For some examples of a completed financial statement go to this link:
Financial Plan.
This a financial plan I did for a non-existing company and it is a plan I will probably never use because I don't believe the industry can grow enough in the long run (6 plus years). It has nothing to do with your business but just look at the I/S, B/S, and CFS. After which look at the key assumptions that all three statements are built around. This plan is fairly detailed, but I did not include quarterly forecasts for the first year which I would do if I were you. Also the break-even analysis should be more detailed than I have done. But it gives you realistic numbers you can look at to see how it all ties together.
Long story short, plan, adjust, plan, adjust, plan, adjust, and plan, and adjust at least every quarter so your plan can get more detailed and more accurate every time.
