Order limits for Shopify

Set order limits.
Test before going live.

Set minimum or maximum quantities for a product or variant, or a minimum order subtotal. Check sample carts before your rules affect Online Store checkout.

Start with 5 free active rules. Upgrade only when you choose.

See the actual app

One product. Mixed sizes. One minimum.

Follow a minimum-quantity rule from draft to activation. See why 11 units fall short and 12 meet the product minimum.

Read the walkthrough
  1. Choose one product and set a combined minimum of 12 units.
  2. Save a draft. Saving alone does not change checkout.
  3. In the sample-cart simulator, 11 units are blocked.
  4. At 12 units, the sample passes this rule.
  5. Review the results before explicitly activating the checked version. Turn checkout rules off when needed.
  6. Start with 5 free active rules on the Free plan.

Product-level rules combine the variants of the same product, not different products. Other active rules can also affect the result.

Choose the limit your store needs

Three practical ways to control orders

Set a minimum product quantity

For a selected product, count its units across sizes and colors toward one minimum. Or set a limit for a specific variant.

Useful when preparing a small batch only makes sense above a minimum quantity.

Cap a product or variant quantity

Set the maximum units of a selected product or variant that a customer can buy in one checkout.

A per-order limit, not a lifetime limit per customer.

Require a minimum order subtotal

Choose a minimum order subtotal in your store currency. Test amounts just below and at your chosen threshold.

A subtotal rule, not a minimum total including shipping and taxes.

One product. Different sizes.

A minimum of 12 can include mixed sizes

For a product-level minimum of 12 T-shirts, 6 Small + 6 Medium = 12 units of the same product. You do not need 12 of each size.

A variant-level rule counts only that selected variant. Product minimums apply when the selected product is in the cart; they do not force customers to add it.

11 units totalBelow this minimum — blocked

12 units totalMeets this minimum — allowed

Illustrative example, not a live checkout. Other active rules can also affect the result.

You decide when rules go live

  1. Create a draft

    Start with a template, select your product or variant, and choose the limit.

  2. Check and test

    Run the Safety Check and test sample carts without changing checkout.

  3. Activate explicitly

    Review and activate the exact version you tested. Turn the rules off when needed.

The app never activates a rule just because you installed it or saved a draft. Sample tests help you review rules; they do not guarantee every checkout scenario.

Check the fit before you install

Where do the rules work?

M10 RuleSafe is built for Shopify Online Store cart and checkout validation. It is not a general order-management tool. POS, draft or manual Admin orders, Order Edit, bundles, subscriptions, and B2B-specific or customer-specific logic are not supported in this version. Buy Now and Shop Pay are not advertised as verified flows.

Can I combine quantities from different products?

Product-level rules combine variants of the same selected product. A shared quantity limit across different products, collection-wide limits, quantity multiples, and lifetime per-customer limits are not currently supported.

Will this add a notice to my product page?

This version validates checkout rules; it does not add a product-page quantity notice or a theme widget. Explain your purchase limits to customers on your store and test your checkout before using rules on live orders.

How do I install or get help?

Use the Shopify App Store link to review permissions and install. Open Help inside the app, visit our support page, or email m10support@daelvista.com. Never send passwords, access tokens, payment details, or customer information.
