Whether you're sending your first corporate invoice or establishing trade credit with suppliers, you've likely encountered the term "Net 30". It is one of the most widely used payment terms in commercial billing, freelancing, and B2B trade.
In this guide, we'll explain exactly what Net 30 means, how to calculate due dates, how early payment discounts (like 2/10 Net 30) work, and the essential rules every small business owner and freelancer must follow to protect their cash flow.
Net 30 is a commercial payment term indicating that full payment is due 30 calendar days after the invoice date. The word "Net" refers to the net (total final) amount specified on the invoice, while "30" represents the number of days the buyer has to settle the balance.
Essentially, offering Net 30 is extending short-term trade credit to your client. You provide goods or perform services today, and the client has a 30-day window to process and pay your invoice.
| Payment Term | Meaning | Best Used For |
|---|---|---|
| Due on Receipt | Payment due immediately upon receiving invoice | New clients, retail, upfront deposits |
| Net 10 / Net 15 | Payment due within 10 or 15 calendar days | Fast-turnaround freelance gigs, retainers |
| Net 30 | Payment due within 30 calendar days | Standard B2B billing, corporate clients |
| Net 60 / Net 90 | Payment due within 60 or 90 calendar days | Large enterprises, enterprise supply chains |
Calculating Net 30 is straightforward, but it is important to remember that Net 30 counts calendar days (including weekends and holidays), not business days.
Some enterprise accounts use Net 30 EOM (End of Month). Under Net 30 EOM, the 30-day countdown begins at the end of the calendar month in which the invoice was issued, regardless of the issue date.
To encourage clients to pay faster, sellers often add an early payment cash discount clause to Net 30 terms. The most common variation is 2/10 Net 30 (pronounced "two ten net thirty").
Imagine you issue an invoice for $5,000 on October 1 with 2/10 Net 30 terms:
Never surprise a client with Net 30 terms (or expect immediate payment) without prior written agreement. Specify payment terms in your contract, estimate, or Statement of Work (SOW) before work commences.
Do not simply write "Net 30" on your invoice. Always include the explicit calendar date so there is zero ambiguity:
Protect yourself by establishing a late payment penalty clause in your service contract (e.g., "A monthly late charge of 1.5% will be applied to balances unpaid past the 30-day due date").
The 30-day clock only starts when the invoice is delivered. Delaying your invoice delivery by a week pushes your actual payday out to 37 days.
Do not wait until Day 31 to contact your client. A polite reminder schedule works best:
