Simple Bundles & Kits allows merchants to easily create product bundles and kits, with options for customizable bundles and inventory management across bundled products.

Whether you're using Simple Bundles 2.0 or 1.0, the integration works out of the box without the need for any additional configuration.

In Simple Bundles 2.0, the shipping rates calculation is based on the child products.

The _ZapietId property from the parent bundle is automatically passed down to the child components in the Shopify order admin.

The ZapietID is used to generate rates. For more information, take a look at our ZapietID guide.

In Simple Bundles 1.0, the shipping rates calculation is based on the parent bundle, which remains in the orders with the _ZapietId.

This integration works for both single SKU configurations (inventory edits) and multi-SKU configurations (order edits with $0 bundle child contents).

The ZapietID is used to generate rates. For more information, take a look at our ZapietID guide.
