We received another question:

>Purchase order mailed to supplier prior to purchase, can Purchase order be considered as an agreement. We are into manufacturing of class 1 medical devices , hence Purchase order can be considered as an agreement of ISO 13485 clause 7.4.2. As Some suppliers are unwilling for sign agreements

Answer:

If the purchase order contains the purchasing information of the products or services that you are sourcing from the supplier, it is valid. However, there should also be some email communication between your company and the supplier to ensure that the supplier will notify you of any changes made to the purchased product or service which could have an impact on the quality and performance of the medical device that you are dealing with.
