"Plans are useless; planning is indispensable," according to Dwight D. Eisenhower, then Commander of the Allied Forces in Europe during WWII. Now, you may be in total agreement with the first part of that statement, but you are really not convinced of the truth of the second part.
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.
