Every organization buys. Some buy raw materials for their production, others procure services, while some just need the occasional office supplies or milk for their coffees. What is common in all the processes, is that goods and services are typically bought from certain selected suppliers. Very often organizations even have contracts made so that you always get the milk delivered from your local Walmart. Companies that need raw materials in their production are highly professional in their purchasing and have clearly defined processes with thresholds in place.
