Case packs / Case quantity

If you sell by the case (e.g. 12 or 24 units per case), you can show an “Add case” button in the Quick Order List. One click adds the full case quantity to the cart, so customers don’t have to type the number themselves.

How it works

For each product variant, you store the number of units in one case. When that number is set, the block shows an “Add case” button next to that variant. Clicking it adds that many units to the cart in one go.

Where to add the case quantity

Case quantity is stored in your store’s custom data for each variant. In Shopify admin, go to Settings → Custom data → Variants. Create a new custom field (metafield) with:

Namespace and key: use either custom.case_pack or custom.case_quantity
Type: Integer (whole number)

Then, for each variant that sells by the case, enter the number of units per case (e.g. 12). Only variants with this value filled in will show the “Add case” button.

Tips

You can use different case sizes per variant (e.g. 6, 12, 24).
Variants without a case quantity simply use the normal quantity field—no “Add case” button is shown.
