A bill (cash memo) serves as legal proof of purchase — it shows that the consumer actually bought the product from a specific seller on a specific date. When filing a complaint before a Consumer Disputes Redressal Commission, the consumer must produce the bill as documentary evidence. Without it, gathering evidence becomes difficult. As noted in the textbook, "in most purchases cash memos are not issued, hence evidence is not easy to gather." A bill also helps establish the purchase price, the seller's identity, and the date — all details the commission needs to decide the case and grant compensation or replacement.
