About the Koss: MOQ & Cart Order Limits

Koss gives you complete control over B2B and retail checkout rules without slowing down your store. Built entirely on Shopify's Checkout Extensibility, it enforces minimum order quantities (MOQ), cart value limits, and case pack multiples with rock-solid stability—even when customers use complex discount codes. Set minimum and maximum order quantities or cart values to protect your margins. Require products to be purchased in specific increments like 6-packs or 12-packs. The app runs 100% server-side using Shopify Functions, so there are zero theme conflicts or performance issues. Customers see automated warning badges on product pages and cart alerts when they don't meet your requirements. Perfect for wholesale, B2B stores, or any shop that needs reliable order limits and quantity rules that actually work.
