POS e-Sign lets retail staff capture waivers and customer consent at checkout. Customers can tap Agree; the app instantly generates a branded PDF and saves it to Content > Files. Attach the waiver reference to the order or customer and export anytime. Customize header/logo and policy text; add optional questions (e.g., initials, ID). Works with Shopify POS - no extra accounts or hardware. Privacy-minded with mandatory GDPR webhooks implemented. No theme edits, Easy
