There are several ways to buy.

There are two procurement methods, namely:

1. Bidding procurement: the buyer puts forward the bidding conditions and contract conditions, and many suppliers bid for quotations at the same time. Through bidding, the buyer can obtain the material supply with more reasonable price and more favorable conditions.

2. Non-bidding procurement: refers to the procurement method of obtaining goods, projects and services by means other than open bidding and invitation bidding.

Extended data:

Purchasing objects are divided into direct materials and indirect materials. Direct materials will be used to constitute all or part of products or services provided by purchasing enterprises to customers, and indirect materials will be used and consumed in internal production and operation activities of enterprises.

Procurement is a process that commercial organisms seek to absorb from the outside world in order to maintain normal operation.

Basic principles of procurement: cost-effectiveness, quality, progress coordination and fair competition.
