General information on payment terms for supply purchases, not legal advice. The legal text quoted is the model Uniform Commercial Code; each US state enacts its own version, and the contract itself can change the default.
Short answer
“Due upon receipt” means the invoice is payable as soon as it is received, with no credit period. For goods the phrase hides a question: receipt of the invoice, or receipt of the goods? Under the model UCC, unless the parties agree otherwise, payment for goods is due at the time and place the buyer is to receive them, so the term is the baseline rather than a special credit term.
Definition and scope
An invoice marked “due upon receipt” carries no stated number of days. Compare it with Net 30, where a credit period is spelled out. In a medical or laboratory supply order the invoice, the delivery of the cartons and the buyer’s check of the contents can fall on three different days. The phrase does not say which of those days starts the obligation, and that is the source of most disputes about it.
How it works for a medical or lab supply order
The UCC default: payment follows receipt of the goods
Section 2-310 of the model Uniform Commercial Code opens with “Unless otherwise agreed” and then provides that “payment is due at the time and place at which the buyer is to receive the goods.” Where delivery is made by way of documents of title, payment is due when and where the buyer is to receive the documents.
Inspection before payment
Section 2-310(b) allows a seller authorized to send the goods to ship them under reservation, but says the buyer may inspect the goods after they arrive, before payment is due, unless inspection is inconsistent with the contract terms. Section 2-513(1) states that, unless otherwise agreed, the buyer has a right before payment or acceptance to inspect goods at any reasonable place and time and in any reasonable manner, and that when the seller is to send the goods the inspection may be after their arrival. Under 2-513(2) the buyer bears the expense of inspection, but may recover it from the seller if the goods do not conform and are rejected.
Where inspection before payment does not apply
Section 2-513(3) removes the right to inspect before payment when the contract provides for delivery “C.O.D.” or on other like terms, or for payment against documents of title (except where payment is due only after the goods are to become available for inspection). See cash in advance and cash on delivery terms for that case.
Invoice date and the start of a credit period
Section 2-310(d) addresses credit: where the seller is required or authorized to ship on credit, the credit period runs from the time of shipment, but post-dating the invoice or delaying its dispatch correspondingly delays the start of the credit period. The same statute therefore ties timing to shipment and delivery, not simply to whenever an invoice is read.
Due upon receipt compared with other terms
| Term | What the sources say fixes the timing | Source |
|---|---|---|
| Due upon receipt (goods, no other agreement) | Payment due when and where the buyer is to receive the goods; buyer may inspect on arrival first unless the contract excludes it | UCC 2-310(a), (b); 2-513(1) |
| Delivery by documents of title | Payment due when and where the buyer is to receive the documents | UCC 2-310(c) |
| Credit shipment | Credit period runs from shipment; post-dating or delaying the invoice delays the start | UCC 2-310(d) |
| C.O.D. or like terms | No right to inspect before payment unless otherwise agreed | UCC 2-513(3)(a) |

What to settle on the purchase order
Because every default above begins “unless otherwise agreed”, the points the statute leaves to the parties are the ones to write down. The list below is drawn from those provisions only.
- The time and place of receipt of the goods. This is the trigger in 2-310(a); a delivery dock, a receiving room and a courier handoff are different places.
- Whether inspection comes before payment. The default in 2-513(1) can be changed, and 2-513(4) presumes that a place or method of inspection fixed by the parties is exclusive.
- Whether delivery is by documents of title. That moves the trigger to receipt of the documents (2-310(c)).
- Which document records receipt. A goods receipt note is the buyer-side record of what arrived, and a three-way match compares it with the order and the invoice before payment.
How an invoice moves through approval is covered in invoice processing.
Common misunderstandings
“Due upon receipt means the day the invoice is opened”
For goods, the model UCC ties payment to receiving the goods (or documents), not to reading the invoice. An invoice emailed before the goods arrive does not, by itself, move that date under 2-310(a).
“Due upon receipt means the buyer must pay before looking at the goods”
Not by default. The buyer’s inspection right in 2-513(1) applies before payment or acceptance, unless the contract is C.O.D. or like terms or payment against documents of title (2-513(3)).
“Due upon receipt is a credit term”
It is the absence of one. A credit period requires an agreed term, and under 2-310(d) it runs from shipment, but post-dating the invoice or delaying its dispatch correspondingly delays when it starts.
“Nothing happens if payment is late”
Consequences for late payment come from the contract or invoice terms, not from the phrase itself. See what triggers a late payment fee.
FAQ
What is due upon receipt meaning?
Payment is due when the invoice or the goods are received, with no credit days. For goods, the model UCC default makes it the time and place the buyer is to receive the goods, unless the parties agreed otherwise.
How does due upon receipt meaning work in a medical supply purchase?
The delivery of the supplies starts the obligation by default, and the buyer may inspect on arrival before payment is due unless the contract excludes inspection (2-310(b), 2-513(1)).
Which documents or terms go with due upon receipt meaning?
The purchase order, the invoice and a goods receipt note, compared in a three-way match; named terms such as Net 30, EOM, C.O.D. and cash in advance are the alternatives.
What mistakes do small buyers make with due upon receipt meaning?
Treating the invoice date as the receipt date, assuming inspection is waived, and leaving the receipt place and time off the order are the three covered above. Whether they apply in a given contract depends on its terms and the governing state law.
