Fussy type covers front of ledger with adhesive label (8)

I believe the answer is:

stickler

'fussy type' is the definition.
(as in a stickler for the rules)

I don't understand the rest of the clue.

(Other definitions for stickler that I've seen before include "One's less than flexible" , "Particular type" , "Pernickety person" , "Punctilious, insistent person" , "One who insists on something, like punctuality" .)

I've seen this clue in The Times.
