HOW FAR BACK DOES GRP SERVICES NEED COPIES OF OUR BILLS?
To begin the audit, we just need one recent, representative month of each bill. You can give us the originals, which we will return, or photocopies. If you like, we will come to your offices to make the copies. While we begin with one month’s bills, we may wish to look at additional bills. Do not discard any old bills, contracts or records while the audit is in progress, since they may provide evidence of how far back a billing error goes. Your Utility service providers seldom provide past bills or if they do there is often a substantial charge for them, so keep your own records archived.
