A second-party audit is when a company performs an audit of a supplier to ensure that they are meeting the requirements specified in the contract. These requirements may include special control over certain processes, standards, etc. Green Partner can perform these audits on behalf of your company. This can be done on-site by reviewing the processes or even off-site (desk audit). It is important to understand that a second-party audit is between your company and the supplier and has nothing to do with becoming certified.
