How many hours per day is planned during an audit? Some companies consider a day in-plant as 6 hours saying the other time is ‘report writing’ time.
Ask the registrar to explain the details of their billing.
Are there any extra charges and tie this down in a written quote. Are travel and lodging expenses covered by the bid? Rental car(s)? There are stories of some companies charging extra for each non-conformance report.
What quality system does the registrar have in place? Request a copy of their Quality Manual.
Will they provide you with their internal audit schedule and results of audits and corrective and preventative action?
