An ISO 9001 certificate proves that your quality management system has been certified against a best practice standard and found compliant. Issued by a third party certification body/registrar, the certificate lets customers know they can trust that you have implemented the necessary internal processes to meet obligations.
The internationally recognized ISO 9001 standard is generic. It is not a product standard, but applicable to any manufacturing or service industry. Created by the International Organization for Standardization (ISO), its objective is to set international requirements for quality management systems.
