The e_marketing plan is built exactly on the same principles as the classical plan. There is no different approach, but there might be some formal differences given by the uniqueness of the internet environment. Many of these differences come from the necessity to ensure a high rate of responsiveness from the customers, since the e_world is moving faster and requires faster reaction from its companies, compared to the traditional offline marketplace.
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.
