Hi - AR Customers can have a general address, a billing address and then different billing contacts can have addresses associated with them. Billing contacts are set up in AR, Setup Contact. For example, Customer ABC on the general tab has one address, the billing tab has the main billing address as well as a billing contact. When printing invoices, the system starts at the billing contact on the AR Customer for non-contract based invoices. If that is blank, it uses the billing address on the Billing tab of the AR Customer setup. If the billing address is blank, it uses the general tab address from AR customer setup. For contract based invoices, it starts with the billing contact on the reference tab of the contract item and if blank moves thru the rest of the hierarchy of contract, billing contact on AR Customer, billing address on AR customer and general address on AR Customer.
