At this point, you may be tempted to skip writing a business plan altogether, viewing it as an unnecessary exercise in jumping_through_the_hoops, suggested by some old business professor who probably never held down a "real" job anyway. Maybe it's okay as an assignment for an MBA class, but it would be just too confining and irrelevant for today's fast_paced business environment. Anyway, you're ready! You've thought about this business venture for a long time and talked it over with friends and everybody agrees it's a great idea. Best to strike while the iron is hot!
Now, in addition, when you know the average number of transactions per customer and you know your average dollar sale per transaction, you can also project how many customers you would need over those 10 years as well. This would tell you everything about what your business would need to do to give you the salary you want. So, wouldn't it be nice to see what a plan like this would look like? Could you do it? It might not be as tough as you might think.
