Quotations for credit are bound by a short, specific time frame so that both price and terms stay current and decisions are made promptly. When a written quote states it is valid for five working days, it means five business days—that is, days when the business is open, excluding weekends and holidays. During those days, the seller commits to the quoted price, instalment amount, interest rate, and other terms. After that period, the terms can be revised or withdrawn because prices, costs, and stock can change, and the quote may no longer reflect current conditions. This short window protects both the seller and the buyer by keeping offers realistic. Five working days is used because it balances urgency with practicality for customers to review and confirm terms, without tying up the seller’s resources indefinitely. Longer periods, like seven or thirty days, increase the risk that conditions change; a full year would be impractical and misleading.
