If you need to change a client's mailing/billing address, but you already have orders in the client's history where the site was that old address, and you don't want to change that history:
1. Open the contact information screen for the client.
2. Go to the Sites tab, and add a New Site that is the new address you need to use.
3. Once you see the new site listed there on the Sites tab, then right-click on it and choose Set as Default.
4. Then feel free to edit the mailing/billing address on the Address/Phones tab to be the new address as well.
