Net 30 means the full amount on an invoice is due within 30 calendar days of the invoice date. If you send an invoice on June 1 with net 30 terms, payment is due July 1. The word "net" refers to the total owed, so it is the amount a client pays when no early-payment discount applies.
Net 30 is one of the most widely used invoice payment terms in business. Freelancers usually meet it the first time they land a client with an accounts payable team. This guide covers what it means, how to work out the due date, how it affects your cash flow, and when it is worth offering.
What does net 30 mean on an invoice?
Net 30 is a payment term that gives the client 30 days to pay. Stripe's guide to net payment terms describes it the same way: payment is due within 30 days of the invoice date.
Three details cause most of the confusion:
- The clock starts on the invoice date. It does not start when the work is delivered, when the client opens the email, or when their finance team approves the invoice.
- Days are calendar days. Weekends and public holidays count. A term in business days has to say so explicitly.
- 30 is the last day to pay, not a target. A client on net 30 can pay earlier, and many pay on the final day.
You will also see "30 days net" and "net 30 days." They mean the same thing.
How do you calculate a net 30 due date?
Add 30 days to the invoice date. When the count runs past the end of a month, carry the remainder into the next one.
| Invoice date | Net 30 due date |
|---|---|
| January 15 | February 14 |
| March 3 | April 2 |
| June 1 | July 1 |
| November 20 | December 20 |
Months have different lengths, so "one month later" is not the same as 30 days. An invoice dated January 15 is due on February 14, not February 15.
Terms rarely say what happens when the due date falls on a weekend. Decide how you want to handle it and write it on the invoice. The simplest fix is to put the actual date next to the term, for example "Net 30, due April 2." The date is harder to misread than the term alone.
What are the common net 30 variations?
Net 30 comes with a few variations. Each one changes who benefits.
| Term | What it means | Example |
|---|---|---|
| Net 30 | Full amount due 30 days after the invoice date | Invoice dated June 1, due July 1 |
| 2/10 net 30 | 2% discount if paid within 10 days, otherwise the full amount is due in 30 | $2,000 invoice: pay $1,960 by day 10, or $2,000 by day 30 |
| Net 30 EOM | Due 30 days after the end of the invoice month | Invoice dated June 12, due July 30 |
| Net 15, net 45, net 60 | Same pattern with a 15, 45, or 60 day window | Net 45 on a June 1 invoice is due July 16 |
Longer terms cost you more. Our guide to net 45 payment terms shows how the invoice date decides which month you get paid, and our guide to net 60 payment terms shows what a 60-day wait does to cash flow and how to negotiate it down.
J.P. Morgan's explainer on net terms gives the 2/10 net 30 definition in the same words: a 2% discount for paying within 10 days, otherwise the full amount in 30.
What does 2/10 net 30 mean?
2/10 net 30 means the client gets a 2% discount if they pay within 10 days of the invoice date. Otherwise the full amount is due by day 30. Our guide to 2/10 net 30 shows the discount math, why it costs you about 37% a year, and when it is worth offering.
How do you write net 30 on an invoice?
Put the term and the date on the invoice, where the client will see them. Spelling out the date removes the arithmetic from their side. If you need an invoice to put it on, the free invoice generator prints both the term and the due date on a PDF.
Invoice date: March 3 Payment terms: Net 30 Payment due: April 2
If you want to offer an early-payment discount or protect yourself against late payment, add the wording directly under the term:
Payment terms: 2/10 net 30. A 2% discount applies if paid within 10 days of the invoice date. Invoices unpaid after the due date are subject to a 1.5% monthly late fee.
A late fee clause has to be agreed before the invoice goes out, so put it in your contract or proposal as well. Rules on late fees and interest differ by country and state, and some places cap them, so check what applies to you.
How do net 30 terms affect your cash flow?
Net 30 means you carry the cost of your own work for a month. Say you invoice $4,000 a month and your clients always pay exactly on the due date. The amount of money waiting to be paid at any moment depends on your terms:
| Payment terms | Average amount waiting to be paid |
|---|---|
| Net 7 | about $930 |
| Net 15 | about $2,000 |
| Net 30 | about $4,000 |
This is a simplified model. It assumes you bill evenly through the month and every client pays on the due date. Real invoices are often paid after the due date, so the wait on net 30 tends to run longer than 30 days.
A new freelancer feels this most. If you send your first invoice today on net 30, your first payment arrives about a month from now, and your rent and software bills do not wait.
Should freelancers offer net 30?
Offer net 30 when a client requires it, not as your default. Many larger companies pay vendors through accounts payable on a fixed schedule, and net 30 is often their policy. Refusing it can cost you the contract. When you have no such client, shorter terms keep more of your money in your account. Net 15 payment terms or net 7 are usually better defaults, and due upon receipt is the shortest of all.
Net 30 tends to work in these cases:
- The client's accounts payable policy requires it
- It is a long-term client with a record of paying reliably
- You have enough savings to cover a month without that income
- The work is a retainer you can plan around
Choose shorter terms in these cases:
- It is a new client you have not worked with before
- The project is small or short
- Your cash is tight
- The client has paid late before
When a client insists on net 30 for a risky project, you can still protect yourself. Ask for a deposit, such as 50% upfront, split the work into milestones with their own invoices, or add a late fee clause. For a wider comparison of terms, see our guide to invoice payment terms.
What if you are the one paying a net 30 invoice?
Net 30 gives you 30 days to pay from the invoice date. Pay by that date. Paying on day 31 makes the invoice late, and a supplier may charge the fee that was agreed.
Because the clock starts on the invoice date, an invoice that reaches you late leaves you less time. If you receive an invoice already two weeks old, you have about two weeks left. Ask suppliers to send invoices promptly, and check whether an early-payment discount such as 2/10 net 30 is on offer before you pay.
How do you get paid on time under net 30?
Net 30 only works if the invoice is easy to pay and hard to forget. These steps help:
- Send the invoice the day the work is done. Every day you wait pushes your payment back by a day.
- Write the due date on it. Use the actual date, not only "net 30."
- Add a way to pay online. Card or PayPal links remove the step where a client has to find a checkbook or wait for a bank transfer.
- Remind the client before the due date. A short note a few days ahead catches invoices stuck in an approval queue.
- Follow up the day after it is late. Use a polite message first, then a firmer one. Our guide to handling late-paying clients includes email templates for each stage.
SolidInvoice handles several of these steps for you. Clients can pay by card or PayPal straight from the invoice, recurring invoices go out on the same date each month, and on Pro and higher plans, payment reminders send automatically on the schedule you set, counted in days after the due date. See the features page or pricing for what each plan includes.
Net 30 payment terms FAQ
What does net 30 mean?
Net 30 means the full invoice amount is due within 30 calendar days of the invoice date. An invoice dated June 1 is due July 1. The client can pay earlier, but the invoice is only late after day 30 has passed.
Does net 30 start from the invoice date or the delivery date?
Net 30 starts on the invoice date unless the contract says otherwise. The delivery date, the date the client opens the invoice, and the date their finance team approves it do not change the clock. If you want terms to run from delivery, write that in the contract.
What is the difference between net 30 and net 60?
Net 30 gives the client 30 days to pay and net 60 gives them 60. The longer window means you wait twice as long for your money. Net 60 and longer terms mostly appear with large enterprise clients, and they strain cash flow for freelancers and small businesses.
What does 2/10 net 30 mean?
2/10 net 30 means the client gets a 2% discount if they pay within 10 days of the invoice date. If they miss that window, the full amount is due by day 30. On a $2,000 invoice, paying inside 10 days costs $1,960.
Is net 30 calendar days or business days?
Net 30 means 30 calendar days. Weekends and holidays are included. A term counted in business days has to say "30 business days" on the invoice or in the contract, because most people will read it as calendar days.
Can I charge a late fee on a net 30 invoice?
You can if the late fee was agreed before the invoice was sent. Put the clause in your contract and repeat it on the invoice. A common clause is 1.5% per month on overdue balances. Check the late fee and interest rules where you and your client are based, since some places cap them.
