+==Abstract==
+This BIP proposes a new term for 'address'
+
+==Specification==
+The new term is:
+''Bitcoin'' '''Invoice''' ''Address''
+
+The ''Bitcoin'' and ''Address'' parts are optional.
+The address suffix should only be used as a transitional step.
+
+A ''Bitcoin'' Invoice ''Address'' is a string of characters that can be used to indicate the intended recipient and purpose of a transaction.
+
+==Motivation==
+Bitcoin addresses are intended to be only used '''once''' and you should generate a new one for every new incoming payment.
+The term 'address' however indicates consistency because nearly everything on the internet or the offline world with the term 'address'
+is something that rarely or even never changes (postal address, email address, IP addresses (depends heavily on the provider), etc.)
+The motivation for this BIP is to change the term address to something that indicates that the address is connected to a single transaction.
+
+==Rationale==
+The reason why we use ''Bitcoin Invoice Address'' or just ''Invoice'' is to emphasize that it is single-use.
+The terms ''Bitcoin'' and ''Address'' are optional for the following reasons:
+For ''Bitcoin'':
+* Useful for multicoin wallets to indicate that it belongs to Bitcoin
+* Indicates a difference between a lightning and an on-chain invoice
+For ''Address'':
+* To not confuse users with a completely new term
+* To show that it is where you send something to
+* To not break backwards compatibility
+
+This gives us the four following possibilities:
+* Bitcoin Invoice Address
+* Bitcoin Invoice
+* Invoice Address
+* Invoice
+
+==Backwards Compatibility==
+To avoid issues, the 'Address' suffix is permitted, but not recommended.
+The suffix 'Address' remains so users should be immediately able to recognize it until the new term is widely known.
+
+==Acknowledgements==
+Thanks to Chris Belcher for the suggestion of the term 'Bitcoin Invoice Address'
