Set order quantity rules without writing a single line of code
Fold lets you control exactly how much customers can buy — minimum orders, maximum quantities, per-product rules, and customer-tag tiers. Install in 2 minutes. No developer needed.
Everything you need, nothing you don’t
Min & max quantity per product or variant
Set different rules for each product in your catalogue. A minimum of 6 for one item, maximum of 2 for another — Fold handles every combination without conflict.
- Per-product and per-variant rules
- Min, max, or both on the same item
- Clear cart error messages
Customer tag tiers — wholesale vs retail
Different rules for different customers. Wholesale buyers can order 50 units minimum; retail customers see standard limits. All driven by Shopify customer tags.
- Tag-based rule overrides
- Wholesale vs retail tiers
- No customer-facing setup
Works with every Shopify theme
Fold validates quantities at checkout level — not just the cart — so no one can bypass the rules. Compatible with all Online Store 2.0 themes out of the box.
- Theme-agnostic implementation
- Checkout-level enforcement
- Works with Shopify Markets
