* “Problem” certificates may not be accepted by auditor
* Result can be that you are charged for uninsured sub
* May be impossible to get reimbursement from sub after the fact
You must know how to “properly” collect certificates of insurance from your insured subs. You have to be very careful because what appears to be a legitimate or valid certificate of insurance can have flaws that will result in it not being accepted by your auditor. At that point, it can be too late for you to go back to the sub to get reimbursement because he could be long gone or you could have lost your leverage if he is no longer doing work for you.
