Let's say your average selling price for your service is 逽ሪ and you have one transaction per year per customer. Using that first years sales example we used above, you would calculate it this way. 造같 divided by 逽ሪ = 968 customers needed for the year. Now if your average transactions per customer are more than 1, then you would need fewer customers. As an example, let's say your average transaction per customers per year is 2Ǒ then 968 divided by 2Ǒ = 387 customers per year. Now let's say you estimate your conversation rate to be 3% of turning leads into paying customers with the advertising method you're going to use, how many leads would need to contact to get 387 customers? Simply divide 387 by 3% and you get 12꽭 leads you're going to need to contact.
I mentioned the financial aspect of a plan earlier, so let me add this. Another fact about financials to consider: not all business activities are about making money. Point being, in most enterprises financial considerations are centric to the document. But there are some other considerations. For example, a few years ago I wrote a plan for a new subsidiary that was focused on developing an inventory of patents. The potential financial returns were years into the future. Those patents may or may not ever have commercial value. Another example is a non_profit enterprise that has need for a complete roadmap for growing their profile in a market, of which a marketing plan would be the centerpiece.
