I need a custom WooCommerce add-on that introduces a full rewards-points system. Shoppers should automatically collect points per purchase, receive a bonus for signing up or simply creating an account, earn extra for writing product reviews, and pick up further points when they follow our social channels or refer a friend. Redemption is straightforward: points must convert either into instant discounts at checkout or unlock tier-based membership perks that WooCommerce can recognise (e.g. by switching the user to a new role or adding them to a members-only group). Core expectations • Clean, self-contained WordPress plugin coded in PHP, compatible with current WooCommerce. • Settings page in wp-admin to define point values for each earning action, expiry rules, and conversion rates for discounts or membership levels. • Visible points balance on My Account, Cart and Checkout pages. • Automatic adjustment when orders are refunded or cancelled. • Hooks/filters so future developers can extend the logic. • Well-commented code and a short README explaining installation, configuration, and all available hooks. Please deliver the finished plugin as a zipped installable file along with the README and a brief changelog.
