When I ask entrepreneurs and small business owners, it is not unusual for not having any marketing plan. I once read that Sir Richard Branson never had any marketing plan when he started the 1st Virgin business many years ago. In fact in one study of entrepreneurship (I couldn't recall the name of the study) was that as much as 50% of entrepreneurs and business owners don't have a business plan and marketing plan when they first started the business.
Pricing _ I once said in my Marketing Plan Breakthrough S6PEC that, "Price is the key determinants of your profits". I stand firm to keep it that way. In your marketing plan, you will address pricing plan for your distributors, customers, multiple segments (some business charge differently _ price discrimination) and cost price i.e. your raw materials and things like that. Not many address price correctly and bear in my mind that we need to standby few pricing plan to respond to the market. Take for example during festive season, if everyone is lowering price and slashed their price or even ignited a price war, what do you do about that? Follow suit or wait? If you want to follow, how far? If you want to wait, how long? You capture all this in pricing plan.
