How long must price lists be retained?

• A. Two years.
• B. Four years.
• C. Six years.
• D. Eight years.

Answer: (B)

The main idea here is how long a business must keep pricing information on file. Price lists document what prices were in effect and when promotions or changes occurred, so having a retention period allows you to show the exact pricing history if an audit, dispute, or inquiry arises.

Four years is the recommended window because it provides a solid balance: it ensures you have enough historical pricing to reference for relatively recent events and regulatory reviews, without keeping records longer than necessary. Shorter periods, like two years, risk gaps where past pricing cannot be verified, while longer periods (six or eight years) add unnecessary burden for everyday operations.

In practice, keep a copy of each price list with the effective date and retire older ones after four years, while retaining any related documentation that explains price changes or promotions.
