Change your checkout
without finding out later.

Checkout tools that answer the only question that matters first — what will this do to a real order? Preview it against a real shopper. Watch it against real orders for a week. Then switch it on.

You write the conditions. It tells you what it will do.
Stops checkout when the address is a PO Box — except when the customer is tagged wholesale.

Written by the rule engine itself — the same code that runs in your checkout.

One rule, seen three ways before it is trusted

Every app we build follows the same shape, because the way store tooling goes wrong is almost never a missing feature — it is a setting that quietly did something other than what it said.

Illustration of the outcome, not a screenshot.

  1. 1

    Preview

    Enter a cart and an address. See exactly what that buyer would get, before and after, with the rule that caused it named. No test orders, no guessing.

  2. 2

    Monitor

    A new rule starts by watching. It records what it would have done to real orders — “this would have blocked 12 checkouts” — while changing nothing.

  3. 3

    Switch on

    Go live on evidence from your own store. One emergency stop pauses every rule at once, and nothing needs support to undo.

In review for the Shopify App Store

Hide, rename or reorder shipping options. Hide payment methods. Block checkout on conditions like postcode, cart total, weight or customer tag — including exemptions, which most rule apps cannot express at all.

Real rules, described by the engine

  • Shipping No express delivery to remote postcodes

    Hides Express when the postcode is 6770, 0800...0899 or 787*.

  • Exemptions Block PO Boxes, except wholesale customers

    Stops checkout when the address is a PO Box — except when the customer is tagged wholesale.

  • Payment No cash on delivery over $300

    Hides the Cash on Delivery payment method when the order total is at least 300 USD.

  • Preview against a test cart and address, with the deciding rule named
  • Monitor mode records what a rule would have done, before it does it
  • A linter that refuses to save a rule which can never fire — or fires on everything
  • Coverage that states where Shopify will not run a rule, including where its own docs disagree
  • An emergency stop that pauses every rule at once
  • A free tier that works on a live store — not dev-stores-only
