Net 30 on an invoice means the customer has 30 calendar days from the invoice date to pay the full amount. An invoice dated June 1 on Net 30 terms is due by July 1. Weekends and holidays count as days.
“Net” is the full amount owed after any discount already shown on the invoice. The number is simply how many days the buyer gets. So Net 15 means 15 days and Net 60 means 60, counted the same way.
How to work out a Net 30 due date
Start the count the day after the invoice date and keep going for 30 days, without skipping weekends.
Months do not matter: Net 30 is 30 days, not “the same date next month”, so an invoice dated January 31 is due March 2 in a year when February has 28 days, or March 1 in a leap year.
The clock starts on the invoice date, not the day the customer opens the email or receives the goods, unless your terms say otherwise. If you send the invoice today, Net 30 means 30 days from today.
Here is every term our invoice generator offers, for one invoice dated on a Friday at the end of October:
| Terms | Days | Due date | Note |
|---|---|---|---|
| Due on receipt | 0 | Friday, October 30, 2026 | Pay when the invoice arrives |
| Net 7 | 7 | Friday, November 6, 2026 | |
| Net 10 | 10 | Monday, November 9, 2026 | |
| Net 15 | 15 | Saturday, November 14, 2026 | Falls on a weekend |
| Net 30 | 30 | Sunday, November 29, 2026 | Falls on a weekend |
| Net 45 | 45 | Monday, December 14, 2026 | |
| Net 60 | 60 | Tuesday, December 29, 2026 |
Two of those dates fall on a weekend, and Net 30 lands on the Sunday after Thanksgiving. A customer reading only “Net 30” might plan to pay on Monday, November 30. Printing the actual date removes the guesswork, which is why the generator writes it under the terms.
What happens when the due date falls on a weekend?
For a private sale, whatever your contract or invoice says. Nothing in general business law moves the date for you, so if Sunday matters, say so, for example “payment received by the next business day is on time”.
Federal agencies work to a written rule. Under the Prompt Payment Act regulations, a payment due on a weekend or federal holiday can be made the next business day without a late payment interest penalty (5 CFR 1315.4). Many businesses follow the same courtesy.
2/10 net 30: paying early for a discount
Some invoices pair Net 30 with a reward for paying quickly. “2/10 net 30” reads as: take 2% off if you pay within 10 days, otherwise pay the full amount within 30. A “1/10 net 30” invoice works the same way with 1% off.
Here is 2/10 net 30 on a sample $4,800 invoice dated October 30:
| If the customer pays | By | They pay |
|---|---|---|
| Within 10 days, taking the 2% discount | Monday, November 9, 2026 | $4,704.00 |
| Within 30 days, no discount | Sunday, November 29, 2026 | $4,800.00 |
Skipping the discount costs $96.00 to keep $4,704.00 for 20 more days. Spread over a year, that is about 37.2%.
About 37% a year is far more than most businesses earn on cash or pay on a credit line, so a buyer with the money usually takes the discount. For the seller, it is a price cut in exchange for being paid 20 days sooner.
Offer a discount only if your margins can carry it, and put both deadlines on the invoice. A buyer who pays the discounted amount on day 14 has not paid in full; decide in advance whether you will accept it or bill the difference.
Net 30 vs Net 15, Net 60 and due on receipt
Shorter terms bring cash in sooner; longer terms win customers who expect time to pay. A rough guide to what each one suits:
| Terms | Typical use | Watch out for |
|---|---|---|
| Due on receipt | New clients, one-off jobs, consumers | “Receipt” of the invoice, not of the goods; still give a date |
| Net 7 or Net 10 | Freelancers and small jobs with regular billing | Some larger clients cannot pay this fast |
| Net 15 | Repeat clients, monthly retainers | Easy to confuse with the 15th of the month |
| Net 30 | The default between businesses | A month of cash you are owed but do not have |
| Net 45 or Net 60 | Large buyers and supply contracts | Plan for the gap before you accept |
You may also see Net 30 EOM, which counts the 30 days from the end of the month the invoice is dated in, not from the invoice date itself. It suits buyers who pay every supplier in one monthly run.
Is Net 30 binding, and can you charge late fees?
Payment terms are part of the deal. If the customer agreed to them, in a contract, a signed estimate or an accepted order, they are expected to pay on time. Terms that first appear on the invoice, after the work is done, are weaker.
A late fee or interest charge works the same way: agree it before the work starts and print it on the invoice. States cap interest rates and some limit late fees, so check yours before you set one. The federal government pays interest on late payments automatically under the Prompt Payment Act.
How to put Net 30 on an invoice
- Choose Net 30 in the payment terms. Our invoice generator fills in the due date from the invoice date.
- Print the date as well as the terms, for example “Terms: Net 30. Due November 29, 2026.”
- Say how you want to be paid, such as the name for checks, your bank details for a transfer, or a card payment link.
- State any early payment discount and late fee you agreed with the client.
- When the money arrives, send a receipt that records the payment.
Make an invoice with Net 30 terms
If the client needs a price before agreeing to terms, send an estimate with the terms written in. Need a document they can pay against before you deliver? That is a proforma invoice.
What is a net 30 account?
A net 30 account is a supplier account that lets a business order now and pay within 30 days, like a short interest-free loan. Some suppliers report those payments to business credit bureaus, which is why new businesses open them to build a credit history. The terms work exactly as on any Net 30 invoice.
