終了 is a general term for 'end' or 'completion' and is more common in everyday speech; 仕納め is more specific to work or tasks and carries a slightly formal, literary tone.
Standard kanji spelling for 'finishing up work or tasks'.
Alternate kanji spelling; less common than 仕納め.
Compound of 仕 (し, 'to do, serve') and 納め (おさめ, 'putting away, finishing'). The exact historical derivation is uncertain, but the word is conventionally associated with completing one's work.
