I found some very old discussions, but looking for more recent. 

Very confused on mapping the addresses correctly, due to different names for some reason between.

for example:

leads: city, state, zip etc... as normal

contacts: Mailing adddress & Other address

Accounts:  Billing address & Shipping address

Books:  Billing address & Shipping address

it seems contacts is the one that is out of touch with the others, so difficult to map books to contacts as the contacts need a billing address and mailing/shipping address.  City wants to map to billing in accounts, and mailing in contacts, but mailing should be shipping in books.  

any easy way to just rename other address as billing address in contacts?
