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 using Tools> Edit Settings > Locations. Click the View link to bring up the Edit Location window.  Add an address and Save.  If a location does not have a specific address, Jackrabbit uses the main address set in Tools > Edit Settings > Organization Defaults.
