Supplier audits, also called second-party audits, aim to assess the technical and organizational capacity of a company to supply products or services.

It is very frequent in subcontracting processes, especially, where the behavior of the supplier or subcontractor is critical for the client, either to guarantee the supply or to guarantee compliance with the client's specifications or legal specifications.

This activity not only guarantees the supply, but also prevents possible legal responsibilities for the buyer.

Large companies usually have their own staff dedicated to this activity, generally from the quality area; In small companies that also need to carry out this activity, it is common to resort to specialized services.
