What does Net 30 mean?
“Net 30” is a payment term on an invoice: the buyer has 30 days to pay the full (“net”) amount. The days are calendar days, so Saturdays, Sundays and holidays all count. The clock usually starts on the invoice date. Some contracts start it on the date the invoice is received, or the date the goods arrive, so check the wording: “30 days from receipt of invoice” can be several days later than “30 days from invoice date”.
Net 30 is not the same as “one month”. An invoice dated January 31 under Net 30 is due on March 2 (or March 1 in a leap year), not February 28. Net 60 and Net 90 work the same way with 60 and 90 days. For the difference between the two kinds of day, see calendar days vs business days.
What if the due date falls on a weekend or holiday?
There is no single rule. Many contracts and accounts-payable teams treat a payment made on the next business day as on time, because banks don’t process transfers on weekends or bank holidays. Others expect the money to arrive by the last business day before. If your terms don’t say, ask, or pay a business day early. Tick the roll-forward box in the calculator to see the next business day.
Example: an invoice dated Friday, November 27, 2026 (the day after Thanksgiving) on Net 30 reaches day 30 on Sunday, December 27, 2026. Moved to the next business day it is due in the US. In Canada and England and Wales, December 28 is the Boxing Day holiday, so it moves again, to .
What does 2/10 Net 30 mean?
2/10 Net 30 (also written 2/10 n/30) offers a 2% discount if the buyer pays within 10 days; otherwise the full amount is due in 30 days. On a $5,000 invoice, paying by day 10 costs $4,900, paying on day 11 to 30 costs $5,000. The calculator shows the day-10 discount date under the result.
For the buyer the discount is worth more than it looks. Skipping it means paying 2% extra to keep the money for 20 more days. That works out at 2/98 × 365/20 ≈ 37% a year, more than most businesses pay to borrow. Other common variants: 1/10 Net 30 (1% discount), 2/10 Net 60, and 3/10 Net 30.
What does EOM mean on an invoice?
EOM means “end of month”. “Net 30 EOM” usually means 30 days after the end of the month in which the invoice is dated: every invoice dated in November 2026 is due on . “Net EOM” on its own, or “due EOM”, usually means payment by the last day of the invoice month. Suppliers use EOM terms to bill once a month and collect on one date. Tick the EOM box in the calculator to count from the last day of the invoice month.
