How due dates are counted
Net 30 means the full amount is due 30 days after the invoice date. An invoice dated October 1 with Net 30 terms is due October 31. Day one is the day after the invoice date, so the count does not include the invoice date itself.
Net 30 EOM means the 30 days start at the end of the invoice month, not on the invoice date. An invoice dated October 12 with Net 30 EOM is due 30 days after October 31, which is November 30.
Weekends and holidays
If a due date lands on a weekend, many businesses treat the next business day as the real deadline. Others expect payment by the date as written. Tick the box above to see the next business day, and state your own rule in the invoice notes so nobody has to guess. This calculator does not know about public holidays.
Choosing payment terms
- Due on receipt or Net 7 improves your cash flow and suits small jobs and consumers.
- Net 15 and Net 30 are common for business to business work.
- Net 45, Net 60 and Net 90 are usually requested by large companies.
- Always write the actual due date on the invoice as well as the terms.
Questions
Does the invoice date count as day one?
No. The count starts the day after the invoice date, so Net 30 on October 1 is October 31.
What does EOM mean?
End of month. Terms such as Net 30 EOM start counting from the last day of the invoice month.
Does the invoice date or the delivery date start the clock?
It depends on your agreement. Most invoices count from the invoice date. If the client receives the invoice late, you may want to say that the terms start on receipt.
