An informal or dialectal term for a counting-house employee or accountant (British English slang).
From 'compt' or 'count' with the diminutive or informal suffix '-ie,' common in British English for creating casual or affectionate nicknames for occupations.
This is the kind of word that survived in small pockets of English—British accountants' offices might have used this term as casual shorthand, but it never made it into official dictionaries.
