CartGate vs Ziva ‑ Order Limits Quantity

Some orders should never happen: an accessory checking out without its base device, two products that can't ship together, or a bundle item bought again on its own. CartGate blocks these carts before checkout. Set rules by product, variant, tag, or collection, and choose to block the cart or warn the customer on the product page. Your rules hold no matter how the customer checks out, including Apple Pay and Shop Pay, so you stop refunding orders that should never have been placed.

Ziva helps you control how many units customers can buy using MOQ, min/max, and step quantity rules. Apply limits by product, variant, collection, or cart, and target by customer tags, login status, email, or market. Use Shopify checkout validation to block fraud, bulk orders, and repeat repurchase attempts. Add low-stock counters and customizable messages, auto-translate by store language, schedule rules, and set lifetime/re-purchase limits per customer.
