From the above discussion it is clear that the business market functions differently from consumer markets. Buying decision especially is more complex owing to many players. If buying decision is a re-purchase than purchasing department would place the order with an old supplier. Companies keep a list of approved vendors from which they choose as per purchase requirement. If buying decision is a modification from previous order in terms of specifications, amount, price, etc. than companies’ looks to have a discussion with suppliers. Purchase department may look to other suppliers for a modification order. If the buying decision is a new product or service than a lengthy process is followed with discussion and meeting between representatives from various departments.
