Serial plaintiffs sue small stores over strikethrough prices, and Shopify keeps no price history to defend you. Price Proof records a time-stamped history of every price and compare-at from install, then audits each discount against U.S. FTC former-price rules and the EU Omnibus directive. It flags compare-at prices the product never sold at, permanent sales, and prices above the 30-day low; each shows the reason and fix. Export clean evidence and fix risky compare-at prices in one click.

• Record time-stamped price and compare-at history automatically.
• Audit strikethrough prices against US FTC and EU Omnibus rules.
