Bill is upset and inflamed (5,6)

Ross

I believe the answer is:

final demand

'bill' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'upset and inflamed' is the wordplay.
'upset' indicates an anagram.
'and'+'inflamed'='andinflamed'
'andinflamed' anagrammed gives 'FINAL DEMAND'.

'is' acts as a link.

(Another definition for final demand that I've seen is " Ultimatum for debtor".)

I've seen this clue in The Mirror.
