The address on the Matter screen is the one used on the actual bills mailed to clients. The address on the Abacus Law Name screen is used to auto-fill to each new matter for that client and to allow massive address changes across matters when necessary. It also allows you to have two (2) addresses in the header section of a bill when requested. If you check the two addresses on the bill check box on the address tab in matter maintenance, you will get the address from the Name screen and the address from the Matter screen. The Name screen address is first.
