We've adopted Invest-for-Excel as our 'go to' solution for any enterprise financial modelling need. As a management consultancy, we are regularly tasked with: - Valuation opinion generation for existing operating companies, often with both prior year actuals & conservative estimates of future growth. Invest for excel allows us to quickly generate these results and then look at the potential value from a standalone perspective, or from the acquirers perspective. We can add debt schedules, equity takeout scenarios and really develop complex 'what if' scenarios for multiple decision makers to review. - We like the built in analytical tools, including Monte Carlo, Spider and Tornado analysis. This helps to develop tools for management discussion around profitability, break-even, and product-line specific contributions to net income. - Debt worksheet is awesome. To build everything yourself that invest-for-excel has standard, would take you quite a bit of time. You could do it, however it would not have the proofing and assurance around error-free calculations that companies really need. The debt / amortization worksheet capability is really something essential that we use for overall debt finance & preferred share calculations. You can setup custom drawdowns, model fees and other costs and make sure these costs and financing cash flows all fold back into the 3-way financial model properly.
