Native Shopify B2B sets catalogs and payment terms, but can't stop a wholesale buyer ordering below your minimum, in the wrong case quantity, or over an account's cap — and Buy It Now / Shop Pay / Apple Pay slip past storefront scripts. WRIT Order Rules enforces your rules with a checkout validation function, so every order, on any path, meets the minimum order value, minimum quantity, maximum cap, and each product's case-pack multiple. Set rules per company, override per buyer, flag case-pack products. Flat price, 0% commission.

• Minimum order value & quantity, plus maximum order caps — set per B2B company
• Case-pack multiples per product: buyers order in full cases, enforced at checkout
• Per-buyer overrides, flat pricing, and 0% commission — never a cut of your orders
• Fail-safe: min/max/quantity rules apply only to managed B2B companies — unrelated checkouts never break
