Checkout rules for Shopify
Stop the orders you can’t fulfil, before checkout completes.
Set minimums, cap quantities, limit where you ship and who can buy. Rules run inside Shopify checkout and keep working with the app closed.

Verdicts come from the same rule engine that runs inside Shopify checkout.
How it works
Pick a template or build a rule
Start from an order minimum, a country list or a customer tag, or combine conditions on the cart, the customer and the delivery address.
Test it on a sample cart
See whether a cart would be blocked and the exact message the shopper gets, before the rule goes live.
Turn it on
The rule runs inside Shopify checkout as a cart and checkout validation. Turn it off any time from the app or from Settings › Checkout.
What you can enforce
Order minimums and maximums
Block carts under or over a subtotal, with a message explaining why.
Quantity limits
Cap items per order or per product, for limited drops and wholesale packs.

Customer access
Require a customer tag for members-only stores, or require shoppers to log in.

Questions
Do rules slow down checkout?
No. Each rule is evaluated by a Shopify Function, inside Shopify’s own checkout, with no calls to our servers.
Where does the shopper see the message?
Shopify shows it in checkout, at the top of the page or next to the field it relates to, and the shopper can’t pay until the cart meets the rule.
What happens if I move from Pro to Free?
Nothing is deleted. Rules that need Pro are turned off, then any rules beyond your oldest 1 rule. Upgrade again and you can turn them back on.
Does the app store my customers’ data?
No. Rules are saved in your Shopify store. Customer details are read by Shopify at checkout and never reach our servers. See the privacy policy.
