Tips
history
讫 is not used freely on its own; it survives in the fixed bookkeeping words 收讫 ('received in full'), 付讫 ('paid in full') and 起讫 ('start and end'). The speech radical 讠 marks an act of declaring done; 乞 supplies the sound.
register
Formal and clerical. You meet 讫 on receipts, invoices and contracts, not in conversation.
