In your commercial property policy you will find a section titled "Policy Conditions." This section of the policy spells out requirements of the policyholder and the insurance company. It covers information about each party's right to cancel the policy, the insurer's right to inspect the property and conditions about abandonment of the property. There are many more conditions though, and it is good idea that you make yourself aware of these provisions.
One of the conditions is the insurance company's right to audit your books and records as they relate to your policy. Depending on your type of operation, you may already be experienced with the audit process. It is mostly painless and the information can usually be found in your accounting and employment records. The examination may take place during the policy period or any time within three years after the policy periods end, however, an audit usually takes place within a few months of your policy renewal.
The insurer will not just randomly go through your records. You will be given a list of requested information to facilitate the process. This process is usually pretty painless as long as you have current and accurate records.
