At home, singer gets bill (7)
I believe the answer is:
invoice
'bill' is the definition.
(I know that bill can be written as invoice)
'at home singer' is the wordplay.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'singer' becomes 'voice' (voice is a kind of singer).
'in'+'voice'='INVOICE'
'gets' acts as a link.
(Other definitions for invoice that I've seen before include "Send bill for payment" , "Statement of money to be paid" , "Statement for goods" , "Statement of money owed" , "Pollen holder" .)
