In order to ensure the satisfaction of buyers and sellers on the Buttress Roots Platform, the platform will evaluate suppliers and their products through various forms, and build a business environment for healthy competition, cooperation and development. Supplier evaluation and rating are mainly based on pre-sales service, order execution, after-sales service, buyer evaluation, engineer evaluation and other aspects. 

1.Pre-sales Service

Considering the particularity of industrial and engineering products, the purchaser's demand for pre-sales consultation is relatively large, and the supplier should cooperate actively. The communication between buyers and sellers in the early stage is mainly based on email and telephone, and the platform will be connected to the consultation window in the later stage.

2.Order Execution

Once the buyer places an order, the supplier needs to certify and execute according to the actual situation of the order. The order involves the control of the production cycle, quality, documentation, packaging, transportation and other aspects of the product. Every part is very important, and the platform will also monitor the execution of the order.

3.After-sale Service

For most products, after-sales service is an indispensable part. The platform will assist suppliers to participate in overseas after-sales service, and the quality of suppliers' after-sales service will be used as the basis for assessment.

4.Buyer Evaluation

Buyers' evaluation of purchased products is very important. Suppliers need to pay attention to customer feedback, which is of great help for product and service improvement.

5.Engineer Evaluation

Buttress Roots Platform has a column of "Engineer Home". Engineers who are successfully certified on the platform can objectively evaluate all purchasers, suppliers and products on the platform. The comprehensive evaluation of engineers will also be used as the platform's assessment of suppliers. 

6.Certification Level

Buttress Roots Platform will comprehensively carry out objective grade certification based on all the conditions of the supplier. It is divided into five levels, A/ B/ C/ D/ E, from high to low, and the certification level will be dynamically adjusted. The level of certification and the evaluation of engineers will directly affect the sales of products, and the platform will also close the sales authority of suppliers depending on the specific situation.
