Credit Terms Explained: Net 30, Net 60, and What They Cost You

Net 30 means pay within 30 days. Net 60 means pay within 60. These are the two most common payment terms in B2B commerce, and most credit managers treat them as a starting point rather than a strategic choice.

That's a mistake. Credit terms are a pricing decision, a risk decision, and a relationship decision made at the same time. Setting them by default — everyone gets Net 30 unless they complain — is how credit teams accumulate slow-pay portfolios without realizing it.

This guide explains how B2B credit terms work, what the standard types mean, and how to set them in a way that actually reflects your customers' risk profiles.

What Credit Terms Mean

Credit terms define when a buyer must pay for goods or services delivered on account. They appear on the invoice, in the signed terms of sale, and in the credit application. When a seller ships product and expects payment in 30 days, the terms are Net 30. The "Net" refers to the total invoice amount — not a discounted figure.

The terms on an invoice are only enforceable if they appear in a signed agreement. An invoice that says Net 30 but has no corresponding signed terms of sale creates ambiguity if the buyer disputes payment timing. Documentation matters more than people realize. See the guide on credit documentation for how to structure this protection.

Common B2B Credit Term Types

Net 30

Payment due in full within 30 days of the invoice date. The standard across most B2B industries. It gives buyers a short window to process the invoice through their AP workflow before payment is due.

Net 30 is appropriate for most creditworthy customers in industries where 30-day payment cycles are standard. If your customers' AP teams run on 45-day cycles — which is common at enterprise companies — offering Net 30 and then chasing late payments is a predictable problem, not a surprise.

Net 60

Payment due in 60 days. Common in manufacturing, distribution, and industries where buyers carry significant inventory or have longer production cycles. Net 60 is not inherently riskier than Net 30, but it extends the window during which a customer's financial condition can change. A customer who was creditworthy when the order shipped may look different 60 days later.

Net 90

Payment due in 90 days. Extended terms that typically indicate either a highly strategic customer relationship or significant buyer leverage. Government contracts, large retailers, and construction industry buyers often demand Net 90 or longer. At these terms, continuous monitoring of the customer's financial health is not optional — it's the only protection you have.

2/10 Net 30

A 2% discount if paid within 10 days; full invoice amount due at 30 days. Early pay discounts incentivize faster cash conversion for the seller at a cost. The math: a 2% discount for paying 20 days early annualizes to roughly 36% APR. Buyers with access to capital find this attractive. Buyers without it can't take advantage.

The implicit assumption is that early pay discounts improve cash flow. Sometimes they do. Often, the customers who take the discount are the ones who would have paid on time anyway, and the customers who stretch to 60 days ignore the discount entirely.

EOM (End of Month)

Payment due at the end of the month following the invoice date. Net 30 EOM means a January 15 invoice is due February 28. This simplifies accounts payable reconciliation for buyers who batch payments monthly. The effective extension can be significant — an invoice sent on the first of the month gets nearly 60 days under Net 30 EOM terms.

COD (Cash on Delivery)

Payment at the time of delivery. No credit extended. Used for new customers before creditworthiness is established, customers coming off a collections hold, or industries where the default terms are shorter. COD is a relationship reset, not a permanent arrangement. Customers who reliably pay COD for six months have demonstrated payment behavior that supports a credit line decision.

Prepayment

Payment before goods are shipped. Used when credit is declined, when a customer has a history of non-payment, or when the order is custom enough that the seller has significant downside risk if the buyer walks away. Prepayment protects the seller completely but creates friction that may push the buyer to a competitor who extends terms.

How to Set Credit Terms by Customer Risk

Blanket terms — everyone gets Net 30 — are operationally simple and strategically blunt. The right approach ties terms to the customer's credit profile.

A structured framework looks like this:

Low risk, established customer: Net 30 or Net 60 based on industry norms. Consider early pay discount if the customer's cash position makes it attractive to them.

Medium risk, newer customer: Net 30. Shorter terms give you more frequent payment data points to monitor the relationship early. Extend terms after 6-12 months of clean payment history.

High risk, thin credit file: Net 15 or COD until the account demonstrates payment behavior. This isn't punitive — it's a structured trial period. Set expectations with the customer upfront.

Strategic customer, high volume: Terms may need to align with what the customer demands. Document the risk decision. Monitor more closely. The revenue may justify the exposure, but the exposure needs to be acknowledged, not ignored.

Terms and Late Fees

Your credit terms should specify what happens when a customer doesn't pay within terms. Standard options:

• Late fee as a percentage of the overdue balance (1.5% per month is common)
• Interest on the overdue balance at a specified annual rate
• Suspension of credit privileges until the balance is cleared

Whatever you specify, it needs to be in the signed terms of sale. A credit manager who adds a late fee to an invoice without contractual backing is creating a dispute, not enforcing a policy. See the trade credit policy template for language that covers late fee enforcement.

The DSO Problem with Credit Terms

Days sales outstanding is the metric most credit teams use to track how well payment terms are being honored. DSO measures how long it takes, on average, to collect on invoices.

The problem: DSO tells you what already happened. It doesn't tell you which customers are about to miss payment, which are building toward a bad debt, or which are deliberately stretching their terms as a cash flow strategy. By the time DSO climbs, the problem is already 30 to 45 days old.

Credit teams that manage their terms portfolio entirely through DSO are measuring the crime scene. The better approach is monitoring the signals that predict payment deterioration before the invoice ages: payment pattern changes, new UCC filings, industry distress, early warning signals from the customer's financials.

For the monitoring side of credit terms management, see the guide on B2B credit risk monitoring.

Dynamic Terms Adjustments

Terms shouldn't be static. A customer who starts on Net 15 and pays consistently within five days for a year has earned Net 30. A customer on Net 30 who has paid at 45 days for the last three cycles is telling you something. The credit team that doesn't respond to these signals is managing a snapshot, not a relationship.

Dynamic terms management requires tracking actual payment behavior against approved terms, not just waiting for invoices to age into collections. This is where credit management software earns its keep — see the guide to B2B credit management software for what to look for in a platform that supports this kind of monitoring.

Credit Terms as a Sales Tool

The credit department in most companies treats itself as a cost center focused on loss prevention. That's a missed opportunity. Terms are part of the offer — and credit teams that adjust terms proactively to reward good payers and attract new customers are generating revenue, not just controlling risk.

A customer who has been on Net 30 for two years and pays consistently within 15 days is a candidate for a proactive limit increase or term extension. That customer is demonstrating that they're cash-flow healthy and that they value the relationship. Offering them better terms before they ask strengthens the relationship and makes it harder for a competitor to win their business with a better offer.

The data to identify these customers exists in your AR system. The question is whether your credit team is looking at it for growth signals or only for risk signals.

When Customers Dispute Terms

The most common dispute in B2B credit: a customer pays on a schedule different from your terms and claims they never agreed to your terms. This is almost always a documentation problem, not a misunderstanding.

If your signed credit application doesn't incorporate your terms of sale by reference, and your terms of sale aren't signed separately, the customer has a plausible argument. Courts have sided with buyers in these disputes when sellers couldn't produce signed documentation of the specific terms claimed.

For the documentation framework that prevents this, see the guide on B2B credit application best practices.

Key Takeaways

Credit terms are not defaults. Net 30 is a starting point, not a universal answer. The credit teams that set terms based on customer risk profiles, document them correctly, monitor payment behavior dynamically, and adjust terms as relationships evolve are the ones who end up with clean portfolios and strong customer relationships. The teams that set Net 30 for everyone and check DSO once a month are always behind the curve.
