We have multiple locations and the business address is not the correct location's address on our statement / invoice.

To ensure that the specific location address displays on the statement/invoice, add a specific location address under the Gear (icon) > Settings > General > Locations (left menu). Click +Add Location to add a new location. Or click the pencil icon to bring up the Edit Location window and update as needed. 

If a location does not have a specific address, Jackrabbit uses the main address set found under the Gear (menu) > Settings > General > Organization Defaults.
