Set a Quote Validity Period That Matches Your Inputs

A quote validity period is a decision window, not a guarantee that every input will remain unchanged. Choose a period your purchasing and production teams can support, then state the date or time zone clearly. Avoid the phrase “valid for a while” or an email thread in which nobody can identify the current offer.

Name the assumptions that matter

Reference the product revision, quantity, currency, material basis, delivery term and any open approval. If a material price is only indicative, label the quote provisional or explain what will be reconfirmed before order acceptance. Do not claim a fixed price while reserving an undefined right to change it at any moment.

The U.S. International Trade Administration's export quotation guidance includes a quotation validity period among the details to consider. The appropriate period for your offer still depends on your own verified inputs and commercial agreement.

When a buyer replies after expiry, issue a revalidated quote with a new reference. Record what changed and what did not. This avoids two emails with the same quote number but different prices, dates or delivery conditions circulating at once.

Worked example (illustrative)

A supplier can issue quote Q-17 against revision A, quantity 500 and a stated expiry date. If the buyer returns after expiry, the team checks material and capacity again and issues Q-18, recording whether the price changed. It does not leave two contradictory “current” versions of Q-17 in separate email threads.
