WooCommerce Force Sells

Force Sells links products so required items, services or fees are added automatically with the main product. Use it when certain items are not optional, when compliance requires an add-on, or to remove decision friction at the cart.

There are two ways to link. A normal force sell adds products in matching quantity, and shoppers can remove or adjust them. A synced force sell locks products to the main item: they can't be removed or edited separately, and quantity and removal follow the main product. Synced items are marked as linked in the cart.

Examples include a required part with a repair service, an installation fee with custom bike wheels, and a setup fee linked to a subscription. For optional add-ons or flexible bundles, use Grouped Products or Product Bundles instead.
