The types of producer purchase decisions are

Direct repurchase, modified repurchase, and brand-new purchase.

Direct repurchase: producers and users continue to buy products from the original suppliers according to the previous order catalogue and basic requirements. This is the simplest way to buy. This kind of procurement buys more low-value consumables, which requires less manpower and does not require joint procurement.

Revised repurchase: producers and users change the trading conditions such as specifications and prices of the original purchased products before buying. Users will negotiate a new supply agreement with the original supplier, or even change suppliers.

Brand-new procurement: the manufacturer or user purchases industrial supplies or services for the first time, which is the most complicated procurement type. The greater the cost or risk of new purchase, the more people participate in the purchase decision, the more information needs to be collected and the longer it takes to make the purchase decision.
