I learned a ton about financial projections while participating in a business plan competition last summer through the Brooklyn Public Library.
Namely: They are the first place investors turn when they get your business plan.
They are dreaded by many a first-time entrepreneur, because...well, they make you question your assumptions more than any other section of the business plan. This is where the rubber meet the road. While your executive summary might be full of flowery language, the financial projections are all about the bottom line.
Further, the financial projections normally need to be delivered in spreadsheet form, making you Excel-phobics have to sit down and wrangle some cells and functions.
So if you are intimidated by this part of the business planning process, don't be. I've got a guide that's made just for you.
