What Does EOM Mean in Payment Terms?
EOM stands for "end of month". On EOM terms the payment clock does not start on the invoice date — it starts on the last calendar day of the month the invoice was issued in. So an invoice dated 3 August and one dated 27 August both start their countdown on 31 August. EOM terms let a buyer batch a whole month of invoices onto one payment cycle.
EOM 30 (Net 30 End of Month)
EOM 30 — also written "Net 30 EOM", "net 30 end of month" or "30 days end of month" — means payment is due 30 days after the end of the invoice month. An invoice dated anywhere in August is due 30 September (31 August + 30 days). This is the most common EOM variant in B2B trade credit.
EOM 60 (Net 60 End of Month)
EOM 60 means 60 days after the end of the invoice month — an August invoice is due 30 October. EOM 60 shows up in longer enterprise vendor agreements; use the Net 60 calculator instead if your contract counts 60 days from the invoice date.
How the EOM Due Date Is Calculated
due_date = start_date + term_days
Switch the basis selector to "Invoice date" or "Delivery date" above if your agreement does not use the end-of-month convention.
