Withly Cart Rules

Stop partial-case and undersized orders at checkout, and reward buyers who order more of each item.

Selling by the case is hard when buyers can check out with one unit. Withly Cart Rules lets you set a minimum order quantity and a case-pack multiple for a product or a single variant. Shopify checkout blocks a cart line that doesn't meet the rule and shows the buyer a clear message naming the item. Add optional quantity tiers, and a line that qualifies gets the highest matching percentage off. Rules apply to every buyer and are checked per cart line. Preview outcomes before you save.

• Block checkout when a cart line is below your minimum order quantity.
• Require each cart line to be an exact multiple of your case-pack size.
• Give the highest matching percentage discount for quantity tiers.
• Apply each rule to a whole product or to one specific variant.
• Preview the checkout result for any quantity before saving a rule.
