A Net 30 account means you receive goods or services now and pay the full invoice 30 days later
A Net 30 account is a business credit arrangement where a supplier ships you products or completes work, and you have 30 calendar days from the invoice date to pay the full amount. No interest accrues during those 30 days—you simply owe the full invoice price when the deadline arrives. The supplier extends you credit based on your business history, creditworthiness, or a signed agreement.
Net 30 is one of several standard payment terms used between businesses. The number always refers to days from the invoice date, not from when you receive the goods. If an invoice is dated January 5 and marked Net 30, payment is due by February 4, regardless of when the shipment arrived at your door.
These accounts are common in wholesale, manufacturing, retail, and service industries. A small business might use Net 30 to buy inventory from a distributor, or a contractor might invoice a client on Net 30 terms. The arrangement helps businesses manage cash flow by separating the moment they acquire goods from the moment they must pay for them.
Key Takeaways
- Net 30 means you owe the full invoice amount 30 days after the invoice date, with no interest or fees if you pay on time.
- The 30-day clock starts from the invoice date, not the delivery date or the date you open the package.
- Payment terms are negotiable—you can request Net 15, Net 45, Net 60, or other arrangements depending on your relationship with the supplier.
- Late payments on Net 30 accounts may trigger late fees, interest charges, or suspension of future credit, depending on the supplier's policy.
- Net 30 accounts typically require a signed agreement or established business relationship; suppliers run credit checks before opening them.
How the 30-day clock works and when payment is actually due
The invoice date is the starting point. If a supplier sends you an invoice on March 10 with Net 30 terms, your payment deadline is April 9. The calendar counts all 30 days, including weekends and holidays. If April 9 falls on a weekend or holiday, most suppliers expect payment on the next business day, though this varies by company policy.
Some invoices include a "due date" printed directly on them—this is the supplier's calculation of the Net 30 deadline and saves you the math. Always check the invoice for this field. If no due date appears, count 30 days forward from the invoice date shown at the top of the document.
The delivery date does not reset the clock. If you order goods on March 1 but they do not arrive until March 20, the Net 30 terms still run from the invoice date (usually March 1), not from March 20. This is why some businesses negotiate different terms—Net 30 from receipt of goods, or Net 30 from end of month—if they need more time after the goods actually land.
What happens if you pay late or miss the deadline
Missing a Net 30 deadline does not automatically trigger legal action, but it does have real consequences. Most suppliers charge a late fee—commonly 1 to 2 percent of the invoice amount—if payment arrives after the due date. Some add interest on top, calculated monthly or daily depending on the agreement.
Repeated late payments or a single large missed payment can result in suspension of your account. The supplier may require payment in advance (called COD, or cash on delivery) for future orders, or they may stop selling to you altogether. If the debt is large enough and remains unpaid for 60 to 90 days, the supplier may refer it to a collection agency or pursue legal recovery.
Late payments also damage your business credit score. Suppliers report payment history to business credit bureaus like Dun & Bradstreet, Experian Business, and Equifax Business. A pattern of late payments makes it harder to open Net 30 accounts with other suppliers in the future, and can affect your ability to secure loans or lines of credit.
Net 30 versus other common payment terms
Payment terms vary widely depending on industry and negotiation. Net 15 means payment is due in 15 days—faster than Net 30 and often used when the supplier wants quicker cash flow. Net 45 and Net 60 extend the payment window to 45 or 60 days, giving the buyer more time to sell the goods or complete the work before paying.
2/10 Net 30 is a discount term: you receive a 2 percent discount if you pay within 10 days, but the full amount is due by day 30 if you do not take the discount. This incentivizes early payment. COD (cash on delivery) means you pay when the goods arrive, with no credit period. Prepayment or payment in advance requires full payment before the supplier ships anything.
The terms you receive depend on your credit history, the size of your order, and your negotiating power. A new business with no payment history may only may have access to for COD or prepayment. An established business with a strong payment record can often negotiate Net 45 or Net 60, or even request a discount for early payment.
| Term | Payment Due | Common Use |
|---|---|---|
| COD | Upon delivery | New customers, high-risk sales |
| Prepayment | Before shipment | Custom orders, new suppliers |
| Net 15 | 15 days from invoice | Fast-moving inventory, tight cash flow |
| Net 30 | 30 days from invoice | Standard business-to-business |
| Net 45 / Net 60 | 45 or 60 days from invoice | Large orders, established relationships |
| 2/10 Net 30 | 2% off if paid by day 10; full amount by day 30 | Incentivizing early payment |
How to open a Net 30 account with a supplier
Most suppliers require a formal application or signed agreement before extending Net 30 credit. You will typically provide your business name, tax ID, bank account information, and references from other suppliers you currently work with. The supplier may ask for your most recent business tax return or financial statements to assess your creditworthiness.
The supplier runs a credit check through business credit bureaus. This check does not affect your personal credit score, only your business credit profile. The decision usually takes a few business days to a week. If approved, you receive account terms in writing—these spell out the payment deadline, any late fees, and conditions under which the supplier can suspend or close the account.
Some suppliers offer Net 30 automatically to businesses with established relationships or strong credit. Others require you to request it. If you are a new customer, ask whether Net 30 is available; the worst they can say is no. If they decline, ask what terms they do offer and what you would need to do to may have access to for Net 30 in the future.
Managing cash flow with Net 30 accounts
Net 30 terms give you breathing room to sell goods or complete work before you have to pay for them. If you buy inventory on Net 30 and sell it within 20 days, you can use the revenue from those sales to cover the invoice when it comes due. This is called a cash conversion cycle—the time between when you pay for something and when you collect money from your customer.
However, Net 30 only works if you actually collect payment from your own customers on time. If you sell on Net 30 terms yourself, you may end up waiting 60 days total (30 days to pay your supplier, then 30 days to collect from your customer) before you see cash. This is why many businesses negotiate different terms with suppliers and customers—for example, asking suppliers for Net 45 while offering customers Net 15.
Track your Net 30 invoices carefully. Set a reminder 5 to 7 days before each due date so you have time to process the payment. Missing a deadline by a day or two can trigger late fees and damage your credit standing. Use accounting software or a simple spreadsheet to log invoice dates, due dates, and payment status.
What to do if you cannot pay by the Net 30 deadline
If you realize you will miss the deadline, contact the supplier immediately—do not wait until the due date passes. Explain the situation and ask whether they will grant a short extension, such as Net 45 instead of Net 30. Many suppliers will work with you if you communicate early and have a history of paying on time.
Put any agreement to extend the deadline in writing, even if it is just an email confirmation from the supplier. This protects you if a late fee is charged or if there is a dispute later about what was agreed. Ask the supplier to confirm the new due date and whether any interest or fees will apply to the extension.
If you cannot reach an agreement and the payment is overdue, the supplier may report it to a collection agency or pursue legal action. At that point, your options narrow significantly. It is far better to negotiate early than to ignore the problem and hope it goes away.
Frequently Asked Questions
Does Net 30 mean I have 30 days from when I receive the goods?
No. Net 30 is measured from the invoice date, not the delivery date. If the invoice is dated January 5, payment is due February 4, even if the goods do not arrive until January 20. Some suppliers offer "Net 30 from receipt of goods" as an alternative, but you have to request it.
What if the due date falls on a weekend or holiday?
Most suppliers expect payment on the next business day. However, this varies by company. Check your supplier's payment policy or ask them directly. Some accept payment on the next business day automatically; others may charge a late fee if you do not pay on the calendar due date.
Can I negotiate Net 30 terms, or are they fixed?
Payment terms are negotiable. You can ask for Net 45, Net 60, or other arrangements depending on your business relationship and creditworthiness. New customers often start with COD or prepayment and earn Net 30 terms after a history of on-time payments. Established businesses can often negotiate longer terms.
Do late fees on Net 30 accounts affect my personal credit score?
Late payments on business accounts are reported to business credit bureaus, not personal credit bureaus. They damage your business credit score, not your personal credit score. However, if the debt is referred to a collection agency and they sue you personally, it could eventually affect your personal credit.
What is the difference between Net 30 and 2/10 Net 30?
With Net 30, you pay the full amount by day 30. With 2/10 Net 30, you can pay 2 percent less if you pay by day 10, but the full amount is still due by day 30 if you do not take the discount. The discount incentivizes early payment and improves the supplier's cash flow.
