Net 14 payment terms give the buyer 14 calendar days from the invoice date to pay the full amount owed, with no deductions. The “Net” means the total is due in full; the “14” is the payment window. For the seller, it’s a short piece of interest-free credit extended to the buyer. For the buyer, it’s a two-week deadline that moves faster than the more familiar Net 30.
Whether Net 14 works in your favor depends on when the clock actually starts, whether an early payment discount is on the table, and what the underlying agreement says about late fees. Those details are worth pinning down before you sign anything or ship anything.
How the 14-Day Clock Starts
Every day in the 14-day window counts, including weekends and holidays. An invoice dated March 3 comes due on March 17, even if that lands on a Saturday. Most accounting systems calculate the due date by adding 14 days to the invoice date, and that is the standard default.
Two variations shift the start date, and they need to be written on the invoice or spelled out in a master agreement to apply:
- Net 14 ROG (Receipt of Goods) starts the 14 days when the buyer physically receives the shipment. This is common when goods travel a long distance and the invoice may arrive well before the delivery does.
- Net 14 EOM (End of Month) starts the 14-day window at the end of the month the invoice was issued. An invoice dated March 10 under Net 14 EOM would come due on April 14.
If the invoice says “Net 14” with no further qualifier, the invoice date is the assumed starting point in most business dealings. There is a wrinkle, though. Under the Uniform Commercial Code’s default rules for sales of goods, payment is due when the buyer receives the goods unless the parties agree otherwise.1Cornell Law. UCC 2-310 – Open Time for Payment or Running of Credit Agreeing to Net 14 is itself an “otherwise,” so the 14-day window governs once both sides accept it.
Where Net 14 Sits Among Payment Terms
Net 14 falls on the shorter side of common B2B payment terms. Knowing what else is out there helps you judge whether to accept it or push back.
- Due on Receipt or Cash in Advance means payment is due immediately or before shipment. Sellers reach for these with first-time buyers or high-risk orders.
- Net 30 is the most widely used term in business-to-business commerce. It aligns with typical monthly accounting cycles and is the usual counter-offer when a buyer wants more room.
- Net 60 and Net 90 appear in industries with longer production or distribution cycles, including manufacturing, construction, and international trade.
- Cash on Delivery has the buyer pay the carrier or seller at the moment of delivery.
Sellers who choose Net 14 usually want cash back quickly without demanding payment up front. It shows up often in food service, perishable goods, freelance and consulting work, and recurring service contracts.
Early Payment Discounts on Net 14
Sellers sometimes offer a small discount for paying ahead of the deadline. The notation looks like “1/7 Net 14,” meaning the buyer can take a 1% discount by paying within 7 days, with the full amount otherwise due on day 14.
These discounts look modest on the invoice but annualize aggressively because the acceleration period is so short. The standard trade credit formula is:
Annualized Rate = [Discount % ÷ (100 − Discount %)] × [360 ÷ (Full Term − Discount Period)]
A 1/7 Net 14 discount annualizes to over 52%. In effect, the seller is paying that rate for the sake of getting cash a week sooner. If you have the cash to take the discount, it is one of the highest guaranteed returns available to a business, and it almost always beats leaving the money in a bank account.
What Happens If You Pay Late
Missing the 14-day deadline puts the buyer in breach of the agreed payment terms. What follows depends on what the invoice or underlying contract says.
Late Fees and Interest
Most sellers put late-payment language directly on the invoice: a flat fee, a percentage of the outstanding balance, or both. Interest on overdue B2B invoices commonly runs around 1% to 1.5% per month, though many practitioners keep the annualized rate at or below 10% to stay comfortably within legal limits across all states. Some states cap the interest rate or flat fee; others do not. Check your state’s usury or commercial transaction statute before setting or agreeing to a penalty.
One point catches people out. Penalty terms are only reliably enforceable if the buyer agreed to them before the transaction. An invoice that introduces a 5% late fee the buyer has never seen before is far harder to enforce than a fee referenced in a signed contract or purchase order. An invoice by itself is not a contract; it’s a request for payment based on a pre-existing agreement. The enforceable terms live in that agreement.
Collections and Trade Credit
Most sellers send a reminder, then a formal demand letter before escalating. If the balance stays unpaid, the account may be turned over to a collections agency or become the subject of a lawsuit. Chronic late payment also damages the buyer’s trade credit reputation, which makes it harder to get favorable terms from other suppliers. That reputational cost is often the more expensive consequence.
When the Invoice Says Nothing About Terms
If an invoice arrives with no payment terms at all, neither side has agreed to Net 14, Net 30, or anything else. The UCC default for sales of goods is that payment is due when and where the buyer receives the goods. When the seller ships on credit, the credit period runs from the time of shipment, though delaying the invoice delays the start of that window.1Cornell Law. UCC 2-310 – Open Time for Payment or Running of Credit
Practically, a buyer who receives goods with no stated terms owes payment right away. Sellers who want a 14-day window need to say so in writing, and buyers should not assume they have 30 days just because “that’s standard.”
How Net 14 Affects Your Books
Payment terms change when revenue and expenses hit your books, and the accounting method you use decides the timing.
Under the cash method, income is recorded when the payment arrives, and expenses when you pay them. A Net 14 invoice issued March 1 and paid March 14 lands as March income. If the buyer pays April 5, the revenue lands in April.
Under the accrual method, income is recorded when it is earned, meaning when the goods ship or the service is performed, regardless of when the payment shows up. A Net 14 invoice issued in March is March revenue even if the check does not arrive until May.
Most sole proprietors and small businesses may choose the cash method. Larger businesses generally cannot: corporations and partnerships whose average annual gross receipts over the prior three tax years exceed a statutory threshold (set at $25 million and adjusted annually for inflation) are required to use accrual accounting.2IRS. Publication 538 – Accounting Periods and Methods3Office of the Law Revision Counsel. 26 USC 448 – Limitation on Use of Cash Method of Accounting
Because Net 14 has such a short window, receivables age quickly. An invoice 30 days past a Net 14 due date is already 44 days old from the invoice date. Most businesses sort receivables into aging buckets (current, 1–30 days past due, 31–60, and so on) and start escalating collections when an invoice moves into the second bucket. If a Net 14 receivable ultimately proves uncollectible, an accrual-method business can write it off as a bad debt expense. A cash-method business never booked the income, so there is nothing to write off.
Negotiating Net 14
Payment terms are a negotiation point like price or delivery. The best time to negotiate is before you need to.
If you’re the buyer, Net 14 can strain cash flow, especially if your own customers pay you on Net 30 or longer. You’re financing a two-week gap out of pocket. Ask for Net 30 up front and frame it around mutual benefit: longer terms let you place larger orders or commit to recurring purchases. Competing quotes give you leverage, and a strong payment history with the seller is your best asset. Businesses that always pay on time earn the right to ask for better terms.
If you’re the seller, Net 14 keeps cash flowing faster, which matters when payroll, rent, and your own suppliers do not wait. Pushing aggressive terms on every customer, though, can cost sales. A workable pattern is Net 14 as the standard for new customers or smaller orders, extended to Net 30 once a buyer proves reliable. Pair Net 14 with an early payment discount to give buyers an incentive rather than just a deadline. And put the terms, including any late fees, in a signed agreement before shipping. Penalty clauses that first appear on an invoice carry much less weight.
A Note on Federal Contracts
Government contracts rarely use Net 14, but if you sell to federal agencies, the Prompt Payment Act sets its own framework. Agencies must pay interest on late payments, calculated from the day after the due date through the payment date, using a 360-day year and a rate set by the Treasury. Interest penalties under one dollar do not need to be paid, and agencies must pay the penalty automatically without the vendor asking.4eCFR. 5 CFR 1315.10 – Late Payment Interest Penalties The interest accrues whether or not you request it.
