Money finally paid to you following crash (5)
I believe the answer is:
dough
'money' is the definition.
(dough can informally mean money)
'finally paid to you following crash' is the wordplay.
'finally' suggests the final letters.
The last letters of 'paid to you following crash' are 'DOUGH'.
(Other definitions for dough that I've seen before include "Lucre" , "Bread mixture; money" , "cash" , "Flour mixture for bread and pastry" , "Paste; money" .)
