Add custom options — dropdowns, swatches, checkboxes, text and number fields — to any product, with conditional logic that shows fields only when relevant. Priced add-ons and bundle components are linked to real product variants. At checkout, Shopify decrements each component's own inventory and lists it on the order, so fulfillment and stock reports stay correct. Build fixed bundles with percent or fixed discounts, and keep the product page in sync with the bundle total.
