It is very difficult to predict how much an individual certification will cost. The Certification Body performing the audit and granting the certificate determines the price of RWS certification. There are several factors that determine the cost: country, travel required by the auditor, overall time spent auditing, and the size and scope of the farm. The best way for a farm to lower the cost of the audit is to be well prepared for the audit ahead of time so that it is done quickly and successfully the first time. For farms that are certified as a group, the same factors will affect the cost of certification, but those costs are distributed across the member farms. The manager of the Internal Control System can significantly reduce the costs by ensuring that there is strong oversight throughout the year, and that all member farms understand the standard, and what will happen during the audit.
