Financial data in a business plan? -

If we are a tech start up, do we have to have our financial s in our business plan, if so, what does it have to indicate and for how long? Its all assumptions?Thanks

Yes you do if you are looking for investors or applying for a business loan. Most investors/banks will want to know how long it will take to recoup the investment plus the desired profit, so they want to see what your expected expenses, sales and profit/loss will be. Even though a lot of the information will be estimates you need to provide some basis for the estimates in order to determine if they are reasonable. The estimates should as a minimum go until the investment/loan will be repaid.If you are funding the enterprise yourself financial data is not essential but it is still useful to monitor how you are doing compared to how you thought you would do.
