Hai
example:-
suppose My bill date is every month 11th
and due date is every month end date let us assume 31st is due date
so now I paid using some 3rd party payment application for cc bill 29/ 30 /31 any of the dates
sure we all know some apps settle same day, some takes time like 3-4 days...
banks consider transaction date or postingdate
cc bill posted after due date
paid before due date but posted after due date
payment datepostingdate
settlement date
transaction date
