Inventory and Ordering: With a little bit of wizardry, Excel can not only keep track of how much inventory you should have, but it can Email you an alert when you get too low on a particular product, making ordering a breeze. Doing the Schedule: Of course, Excel can be used to graphically display what times any given employee will be on the clock and thus make it easy to ensure that all of the necessary coverage is there for you. Customer Tracking: Few businesses need to track customers more accurately over a longer period of time than an auto shop; Excel offers you the power to do just that. By setting up an entry form that gathers the necessary information and then stores it deep in another sheet, you can easily keep records on hundreds of customers and their vehicles over months and years. Receipts: Because of an auto shop's specific needs when it comes to breaking down parts, labor, taxes, and other charges, Excel makes for an excellent receipt_making program.
Also, how long is your investment horizon? Is it really that important to you to project out to 30 years or is 3λ years sufficient along with a terminal value that represents the expected NPV beyond 5 years? Usually this latter approach works best and looks the most credible to potential investors. There are numerous ways to calculate terminal value including multiples, current market values projected forward, and round guesstimates. Obviously these decisions are affected by your personal preference and the type of investment for which you're calculating present value.
