⑫How to manage large quantities of materials?

1.We have no materials in stock. After receiving your order, we will purchase materials immediately.

2.We require the material supplier to attach the preparation sheet when delivering the materials, and mark the type of materials with a magic pen on the materials.

3.The person in charge of the warehouse of our company will check the preparation invoice, type and size of the arrived materials, attach the processing drawings to the materials, and then put them on the site. In this case, there is almost no possibility of wrong materials in the company.
