3 statement financial model: How to build from start to finish
Income statement / cash flow => flow statements, represents period of time
Balance sheet => represents one specific moment in time
Income statement => money you made and expenses related to those sales
Cash flow => changes in what you own and what you owe (fundraising/debt/cash, for example off P&L)
Step 1        Build income statement => leave depreciation & interest blank
Step 2        Create CAPEX and depreciation schedules
Step 3        Build balance sheet on historical #s
Step 4        Tied cash flow to the balance sheet
