What are the purchase instructions for stainless steel manhole covers and stainless steel square manhole covers?

Matters needing attention in purchasing stainless steel manhole covers and stainless steel square manhole covers:

1. The specifications and models of purchased materials shall be consistent with the purchase plan (the purchase plan shall be available for purchase).

2. The quality standard of purchased materials should be consistent with the arrival of goods (do a good job in arrival acceptance).

3. When purchasing materials, you'd better choose the payment method that is beneficial to you (payment after qualified use, payment after acceptance, payment after arrival, delivery with payment, advance payment, and finally no way to pay first and then deliver).

In addition, delivery date, delivery place, transportation cost, etc. Must be accurate with each other, and at the same time, when signing the contract, fill in all the standard samples.

Is there any payment after the goods are accepted? I have never met anyone who can pay after inspection. I can only pay cash or transfer money after inspection by the supplier in the past. .....

Pay attention to the acceptance of purchased and paid products. No matter how busy you are, you must check them before paying.

Otherwise, once the manufacturer gets the money, if there is any quality problem, it will default. Even if you don't, you have to make more than n calls before you are willing to handle it.
