Receipt of goods payment terms, usually abbreviated ROG, start the buyer’s payment clock on the day a shipment physically arrives rather than the day the seller cuts the invoice. If a contract reads “Net 30 ROG,” the thirty-day credit period begins when the goods land at the buyer’s dock. That single change shifts transit-time risk to the seller and gives the buyer time to inspect the shipment before any deadline starts running.
How ROG Differs From Invoice-Date Terms
Under standard Net 30 terms, the buyer owes payment within thirty calendar days of the invoice date. If the seller invoices on March 1 and the shipment doesn’t arrive until March 20, the buyer has already burned twenty of those thirty days waiting on the carrier. ROG terms ignore the invoice date entirely. Same contract, same dates, but written as “Net 30 ROG,” and the thirty-day window opens on March 20. Payment is due April 19, not March 31.
That’s why ROG shows up most often in industries with long or unpredictable transit: ocean freight, customs clearance, distant suppliers, perishables where the buyer needs to verify product condition before paying. The seller accepts a longer wait for cash, which is one reason ROG terms sometimes come with slightly higher unit prices or shorter credit windows than an equivalent invoice-date arrangement.
Calculating the Deadline
Once the receipt date is confirmed, the math is simple. Treat the day the goods arrive as day zero, count the credit period forward in calendar days, and the last day of the count is the payment deadline. The date printed on the vendor’s invoice is not the trigger and should not drive the calculation.
This is where accounting errors tend to appear. Most ERP systems have a field for the receipt date, but some older platforms require a manual override of the invoice date, and if that override doesn’t happen the system will schedule payment against the wrong deadline. A shipment invoiced March 1 and received March 20 under Net 30 ROG is due April 19. Anything earlier means the buyer paid faster than the contract required; anything later triggers late fees.
Early Payment Discounts
Many ROG contracts stack a cash discount on top of the credit period. The most common structure is “2/10 ROG, Net 30”: two percent off if the buyer pays within ten days of receiving the goods, full amount due at thirty days otherwise.
The ROG modifier makes these discounts much more useful than their invoice-date equivalents. Under standard 2/10 Net 30 terms, a two-week transit delay can consume the entire discount window before the buyer even opens the shipment. With ROG, the ten-day discount window doesn’t open until the goods reach the dock, so the buyer can inspect and still capture the savings. A two percent discount for paying twenty days early works out to roughly 36 percent annualized, which is why accounts payable teams treat discount capture as a priority rather than a nice-to-have.
Less common variants exist: 3/15 ROG offers three percent off for payment within fifteen days of receipt, and some contracts stack multiple tiers with a larger discount for faster payment and a smaller one for a slightly longer window. The format is always the same: discount percentage, slash, number of days, “ROG” to anchor the countdown to delivery.
Documenting the Receipt Date
The receipt date is the single most important data point in an ROG arrangement. Disputes about it can trigger undeserved late fees or blow discount windows. Three documents typically establish it:
- The bill of lading lists what was shipped and the terms of delivery. It confirms what left the seller’s facility but does not prove what arrived or when.1Legal Information Institute. Bill of Lading
- The carrier’s delivery receipt, timestamped and signed at the receiving dock, is the document most accounting teams treat as the official trigger for the ROG clock.
- The buyer’s internal receiving report confirms the physical count matches the shipping manifest and notes any visual damage. Discrepancies here can affect which portions of the shipment start the payment clock and which don’t.
Companies with Electronic Data Interchange systems can automate the handshake. The EDI 856 Advance Ship Notice tells the buyer what’s coming, and the EDI 861 Receiving Advice sends a confirmation of receipt back to the seller. The electronic timestamp becomes the agreed-upon receipt date and feeds directly into accounts payable, eliminating manual data entry and after-the-fact arguments about when goods actually arrived.
Whatever the system, record the receipt date the same day goods arrive and reconcile it against the carrier’s delivery receipt before the end of the business day. AP teams that wait a week to enter it can lose discount days or, worse, create an internal record that contradicts the carrier’s paperwork.
Damaged, Partial, or Nonconforming Shipments
ROG terms get complicated when the shipment doesn’t match the contract. The Uniform Commercial Code, adopted in some form by every state except Louisiana for the sale of goods, gives buyers three options when goods don’t conform: accept everything, reject everything, or accept some commercial units and reject the rest.2Legal Information Institute. Uniform Commercial Code 2-601 – Buyers Rights on Improper Delivery
Rejection has to happen within a reasonable time after delivery, and the buyer must promptly notify the seller.3Legal Information Institute. Uniform Commercial Code 2-602 – Manner and Effect of Rightful Rejection Sit on the goods too long and the failure to reject counts as acceptance, which means the contract price is owed. Damages can still be claimed after acceptance, but the leverage is gone.
For partial shipments, well-drafted ROG contracts spell out what happens explicitly. Without that language, the UCC default applies: the buyer can accept the conforming units and reject the rest, and the ROG payment clock runs on the accepted portion from the date of receipt. The rejected portion generates no payment obligation until the seller cures the problem.
If the buyer accepts goods knowing they’re defective rather than rejecting the whole shipment, UCC Section 2-717 permits deducting damages from the remaining price, provided the buyer notifies the seller of that intention.4Legal Information Institute. Uniform Commercial Code 2-717 – Deduction of Damages From the Price The deduction reduces what’s owed when the ROG deadline hits, rather than forcing a separate refund claim later.
How FOB Terms Interact
The shipping term chosen alongside ROG determines who owns the goods in transit, and that changes how the arrangement behaves. Under FOB Destination, the seller keeps ownership and risk until delivery, which pairs cleanly with ROG: the seller carries the transit risk and the payment clock waits for arrival.
Under FOB Origin, the buyer takes ownership when the carrier picks up the goods, even though the ROG clock hasn’t started. If something is damaged in transit, the buyer technically owns damaged inventory it hasn’t paid for and may want to reject. Contracts combining FOB Origin with ROG should spell out what “receipt” means in that scenario to avoid disputes over whether damaged goods trigger the payment period.
Late Payment Consequences
Missing an ROG deadline carries real costs, and the specifics depend on who the buyer is.
Private Commercial Contracts
Late fees on business-to-business invoices are governed by the contract itself and, in some cases, state law. A common structure is a monthly interest charge of 1 to 1.5 percent on the overdue balance, roughly 12 to 18 percent annualized. Over 30 states have no statutory cap on commercial late fees, so the contract terms control. Where state law does set a ceiling, rates vary. One requirement is universal: the late fee must be spelled out in the written contract. A seller who never mentioned late fees in the purchase agreement can’t add them later.
Federal Government Contracts
Agencies buying goods under ROG terms are subject to the Prompt Payment Act, which requires the government to pay interest penalties automatically when it misses a payment deadline.5Office of the Law Revision Counsel. 31 USC 3902 – Interest Penalties For the first half of 2026, the Treasury Department set that penalty rate at 4.125 percent per annum.6Federal Register. Prompt Payment Interest Rate; Contract Disputes Act Interest accrues from the day after the deadline through the date of actual payment, and unpaid penalty amounts compound after 30 days by being added to the principal balance. The vendor does not have to request the penalty; the agency pays it automatically.
