Solution Digest: MOQ Rules

• Server-side enforcement via Shopify Functions across cart, drawer, and checkout
• Built-in simulator: test a cart, see pass/fail and which rule fired
• Plain-English summary on every rule and impact preview before publish

Server-side MOQ enforcement for B2B and wholesale stores. Multi-currency cart limits, multi-language errors, schedule windows.

Set minimum order quantities, max cart limits, and pack-size rules that actually enforce — at the cart, cart drawer, Buy Now, and checkout (including express). Built on Shopify’s Cart and Checkout Validation Function — rules can’t be bypassed.

Built for B2B and wholesale: target rules to specific customer segments by tag. Set different minimums for wholesale vs retail, VIP vs regular, in a single rule that applies the right limit to the right shopper.

Multi-currency aware: set per-currency cart-value thresholds for stores on Shopify Markets. EUR shoppers can see one minimum, USD shoppers another, all from the same rule.

Multi-language storefront errors: write the customer-facing error in every language your store supports. The engine matches the shopper’s locale automatically — French shoppers see French, German shoppers see German, all from one rule.

Schedule rules for flash sales, weekend wholesale, or seasonal MOQ. Set a start date, an end date, or both. Rules outside their window stop enforcing automatically — no manual toggle, no forgetting to turn them off.

Three things this app is built around: a rule simulator (test a cart, see exactly which rule fires), an impact preview before publish, and a plain-English summary on every rule. Clean uninstall with no theme residue. GDPR webhooks implemented. No customer PII stored.
