Smart Add-Ons adds custom product options to WooCommerce: text, dropdowns, checkboxes, image swatches, dates, file uploads and name-your-price fields. Conditional logic on every plan shows a field only when an earlier answer needs it, and a live price preview updates as shoppers choose. Pro adds formula pricing, add-on analytics and A/B testing of option groups, and covers 3 sites. GPL code, 30-day any-reason refund, and a live demo store to try first.
