Checkout rules your customers can't get around.

Hide or rename payment and shipping options, set minimum and maximum orders, and block orders that break your rules. Shopify enforces them at checkout.

Cartsmith rules list: payment, delivery and checkout rules

Three kinds of rules, one app

Start from a template or build your own. Each rule can depend on the cart, the address, the products and the customer.

Payment rules

  • Hide cash on delivery for big orders
  • Offer a payment method only in some countries
  • Rename or reorder payment methods

Delivery rules

  • Hide express shipping for heavy or dangerous items
  • Offer local pickup only to nearby postcodes
  • Rename shipping options

Order limits

  • Minimum and maximum order amount or quantity
  • Maximum per product, counted across all its variants
  • Sell in packs (multiples of 6, 12, …) or block an order

Built not to break your checkout

The most common complaints about checkout apps are about broken checkouts and limits that are easy to get around. Cartsmith is built the other way.

Enforced by Shopify

Rules run inside Shopify's checkout, so editing the cart page or the checkout link can't get around them.

Never hides everything

If your rules would hide every payment method or shipping option, Cartsmith hides none, and if a rule fails, checkout carries on.

No theme code

Nothing is added to your theme or products, so there is nothing to clean up when you uninstall.

Test before you go live

Describe a cart and see which options are hidden, renamed or blocked, before a customer does.

Questions

Does Cartsmith change my theme?

No. Rules run as Shopify Functions inside checkout. Nothing is added to your theme or products.

Can customers get around a limit?

Order limits are checked by Shopify when items are added to the cart and again at checkout, so changing the cart page or the checkout link doesn't help.

Can I rename the credit card option?

Shopify keeps its own label on the card option. Renaming works for other methods, such as bank transfer or cash on delivery.

What data does Cartsmith keep?

None on our side. Your rules are saved in your own Shopify store and checkout data stays inside Shopify. See the privacy policy.

What happens if I uninstall?

Shopify removes Cartsmith's rules from your checkout and cancels any subscription.
