K1 Pre-Order is an embedded Shopify application. Merchants configure pre-order behavior through rules. A rule targets products, collections, or selected variants and defines:
- when an item is shown as available for pre-order;
- which payment options are offered;
- which storefront elements are rendered;
- whether Shopify inventory policy is changed;
- whether a pre-order quantity limit applies;
- when the rule becomes active or inactive;
- which order tags and line-item properties are added.
