End of Month (EOM) Invoice Due Date Calculator
Calculate payment due dates for EOM and EOM+15/EOM+30 invoice terms.
EOM terms anchor to month-end, not invoice date — an invoice on July 5 and July 25 may share the same EOM base date. Manufacturing and wholesale buyers use this for consolidated AP runs.
