DAC Audit Services (DACAS) is referred to as an ISO Audit Provider (IAP). We have over 20 years’ experience in ISO auditing for registration, compliance, and training. As a result of this extensive ISO background, we receive requests for audit support services from clients, registrars, secondary parties, OEM’s, and special interest groups/associations.

We have no preconceived ideas on how you should apply an ISO standard to your business. It is your company, and you know the best way to apply the requirements of the standard to your business. We assess whether your management system does, in fact, comply with the relevant standard, regardless of how you have done it.

Our role as your ISO Audit Provider is to represent you exclusively in all matters pertaining to registration, certification, internal auditing, and/or training. When you retain us you will discover the exceptional service and support that we at DAC Audit Services provide. Learn more about us.
