Sushinet · Live on the Shopify App Store
Hide, rename and reorder shipping options. Hide payment methods. Block checkout on postcode, cart total, weight or customer email — with exemptions. Then watch the rule against your real orders before it changes a single one.
Stops checkout when the address is a PO Box — except when the customer is tagged wholesale.
Written by the rule engine itself — the same engine that is compiled into the checkout Functions, so the sentence and the behaviour come from one source and cannot drift apart.
One rule, one outcome, shown before and after. This is the whole job.
Illustration of the outcome, not a screenshot.
No express delivery to remote postcodes
Hides Express when the postcode is 6770, 0800...0899 or 787*.
Block PO Boxes, except wholesale customers
Stops checkout when the address is a PO Box — except when the customer is tagged wholesale.
No cash on delivery over $300
Hides the Cash on Delivery payment method when the order total is at least 300 USD.
Rules compile into Shopify Functions and run on Shopify's infrastructure. Once published, our server plays no part in a checkout — if we were offline, your checkout would keep enforcing exactly what it already was.
Nothing is injected into your storefront — no script, no pixel, no snippet. The most common way a store app breaks a store is by editing the theme, and there is no version of this app that can.
One live rule on each checkout area, on your real store, with unlimited draft and monitor rules, the preview and the linter included. Not a development-store trial — you can judge it on your own traffic before paying anything.
Six actions. A rule does one of them when its conditions match.
The buyer never sees it, rather than seeing it fail at the last step.
Say what it means to your buyer instead of what the carrier calls it.
Put the one you want chosen where it will actually be chosen.
For example, cash on delivery above a cart total you set.
The same clarity, one step later in the checkout.
With a message you write, in each language you sell in.
Install Ruleproof and build your first rule in a few minutes. The free plan works on a live store, every rule starts in draft, and nothing touches a real checkout until you set it live.
Yes. A rule can be put on a schedule — active only at certain times of day, days of the week, months, or date ranges — so you can, for example, hide same-day delivery after a 12pm cutoff and bring it back the next morning. Schedules are evaluated in your store's own timezone and stay correct across daylight-saving changes.
Yes. One rule can be live on each checkout area — shipping, checkout blocking and payment — on your real, paying store. Unlimited rules in draft and monitor mode, the preview, the activity log and the linter are all included. This matters because "free" in this category often means development stores only, which is no use for deciding whether something works on your actual traffic.
No. Ruleproof installs from the App Store, opens inside your Shopify admin, and compiles each rule into a Shopify Function that runs in the checkout itself. Nothing is injected into your theme or storefront, so there is no code to add and nothing to remove if you uninstall.
Country, postcode or ZIP, cart total, total weight, a product or collection in the cart, a customer email, and currency. On the paid plan you can combine those with and, or and exemptions — for example "block checkout to PO Boxes, except for customers tagged wholesale".
Nothing. Rules are compiled into Shopify Functions and run on Shopify's own infrastructure, so once a rule is published our server is not involved in a checkout at all. If we were offline you would be unable to open the admin and edit rules — your checkout would carry on enforcing exactly what it was already enforcing.
A test mode tells you what happens to an order you construct yourself. Monitor mode records what a rule would have done to the orders your store actually received — "this would have blocked 12 checkouts last week" — while changing nothing. You go live on evidence from your own traffic rather than from a test order.
