How do Quote and Invoice compare side by side?
The table below compares Quote and Invoice across 9 dimensions, from what it is to choose it when.
Side-by-side comparison
| Dimension | Quote | Invoice |
|---|---|---|
| What it is | A supplier's statement of the items, quantities and terms it proposes to sell. Under FAR 13.004, "a quotation is not an offer" and cannot be accepted to form a binding contract. | A supplier's request for payment for goods or services supplied under an order. Federal rules call a compliant one a "proper invoice" (FAR 52.232-25). |
| When it appears in the buying trail | Before an order: quote, then purchase order, then acceptance, then delivery, then invoice. | After the order is placed and the goods are delivered or accepted; payment follows the invoice. |
| Does it commit the buyer? | Not by itself. FAR 13.004: issuing an order in response to a quotation "does not establish a contract"; the order is the offer, and a contract is established when the supplier accepts it. | It asks for payment on what was ordered. The commitment came from the purchase order and its acceptance, not from the invoice. |
| Does it commit the supplier? | Generally not, unless the quote states it will be held open. Under UCC 2-205, a merchant's signed written offer that gives assurance it will be held open is not revocable, for no longer than the stated time and never beyond three months. | It states what the supplier says is owed; it does not create the purchase obligation. |
| Which one applies to a clinic or reseller account? | The quote, while the account is deciding what to order and on what terms. | The invoice, once an order has been placed and delivered, as the document that AP matches and pays. |
| What to check on it | Items and quantities, unit terms, payment terms, shipping terms, and the validity period the quote itself states. | Order or PO reference, invoice date and number, item description, quantity and unit price, shipping and payment terms, payee name and address (the content list in FAR 52.232-25(a)(3)). |
| How the payment date is set | A quote does not start a payment clock. | Under FAR 52.232-25, payment is due the later of the 30th day after the billing office receives a proper invoice or the 30th day after acceptance of the supplies. Commercial accounts follow the terms agreed with the supplier. |
| What it costs or commits the buyer to | Nothing until the buyer places an order; the quote shows the proposed cost. | The amount due for what was ordered and delivered, on the stated payment terms. |
| Choose it when | You are comparing suppliers or confirming terms before ordering: ask for a quote. | You are reconciling a delivery and paying: the invoice is the document to match against the order. |

Common questions
Common questions about Quote vs Invoice
What is the difference in quote vs invoice?
+
A quote is a supplier's proposal made before an order; under FAR 13.004 it is not an offer and cannot be accepted to form a binding contract. An invoice comes after the order and delivery and asks for payment.
Which one applies to a clinic or reseller account?
+
Both, at different points. The quote applies while the account decides what to buy and on what terms; the invoice applies after an order is placed and delivered, when accounts payable matches it to the purchase order and pays it.
What does each cost or commit the buyer to?
+
A quote commits the buyer to nothing by itself; under FAR 13.004 the buyer's order is the offer and a contract forms when the supplier accepts. An invoice asks for payment of the amount owed for what was ordered, on the payment terms agreed.
How do I choose between them?
+
You do not choose between them; they are different steps. Ask for a quote before ordering to see proposed items and terms, and expect the invoice after delivery as the payment request to check against the order.
