This is the real rule engine, running in your browser. Pick a rule type, change the cart, and see exactly what your buyers would see.
Cart total is $120
Most stores end up paying four separate subscriptions to do this. Puco Checkout Rules covers all of it with one rule engine and one bill.
Hide, sort and rename payment methods
Stop chargebacks and failed orders before they happen. Hide Cash on Delivery on high-value carts, push your cheapest gateway to the top, or rename a confusing provider name into something buyers recognise.
See it in the demoHide, sort and rename shipping rates
The same rule engine, applied to shipping. Hide paid rates once an order qualifies for free shipping, preselect the rate you want as default, or rename "Standard" into "Free shipping — 3 to 5 days".
See it in the demoBlock checkout with your own message
Stop an order from going through when it breaks your rules, and show the buyer exactly why. Attach the error to any of 13 checkout fields so the message appears right where the problem is.
See it in the demoDiscount delivery rates conditionally
Reward the carts you want. Apply a percentage, a fixed amount or a flat rate to any shipping option — automatically or behind a discount code, on a schedule you control.
See it in the demoThese are the actual templates inside the app. Pick one and every field — conditions, methods, messages, discount values — arrives filled in.
Hide Cash on Delivery when the buyer picks a shipping method that your courier cannot collect cash on.
Hide Cash on Delivery once the cart total goes above the amount you set.
Keep Cash on Delivery for customers you already know, and hide it from everyone who has not bought yet.
Show a payment method only in the Shopify Markets where it is actually supported.
Move the rate you want buyers to pick to the top of the list so it is preselected.
Once an order qualifies for free shipping, hide the paid rates so nobody overpays by accident.
Hide rates that cannot carry certain products — oversized, fragile or restricted items.
Stop checkout until the cart total reaches the minimum you set.
Stop checkout when the shipping address looks like a PO Box.
Stop orders that contain products you cannot ship to that buyer.
Stop checkout when the cart holds more items than you allow in one order.
Automatically apply a free shipping discount when the order goes above the amount you choose.
Take a percentage off your Express rate when the order is big enough to justify it.

Don't check any rules or conditions — the customization always applies at checkout
Describing a rule is faster than building one, and testing it on your live store should never risk a real order. Both are handled.
Type what you want in plain English — "hide COD for orders over $200" — and Puco AI fills in the whole form for you. You review every field before anything goes live.
Turn on Testing mode and the rule only fires when the first name at checkout contains "testing". Real buyers see a completely untouched checkout while you verify.
Thirteen ready-made rules built from what merchants actually ask for. Pick one and every field — conditions, methods, messages, discount values — is filled in for you.
Rules compile to WebAssembly and execute inside Shopify at checkout. Nothing is injected into your theme, so there is no script to slow your store down.
While Testing mode is on, the rule only fires when the checkout first name contains “testing”. Everyone else shops as normal.
A blocked checkout can attach your message to any of these 13 fields.
Payment rules, delivery rules, validation and shipping discounts are usually sold as separate apps. Here they share one rule engine, one dashboard and one bill.

Install Puco Checkout Rules, create a payment customization, choose Hide as the action and pick Cash on Delivery from the list of 74 built-in payment methods. Then add a condition such as "Total amount is greater than 200". The method disappears at checkout whenever that condition is true.
No. Puco Checkout Rules runs on Shopify Functions, which are available to all Shopify plans. Hiding, sorting and renaming payment and delivery methods, checkout validation and shipping discounts all work without Shopify Plus and without editing checkout.liquid.
No. Rules are compiled to WebAssembly and executed by Shopify itself during checkout. Nothing is injected into your theme and no external script is loaded, so there is no added page weight or network request.
Yes. Every rule has a Testing mode. While it is on, the rule only applies when the first name entered at checkout contains the word "testing". Every other shopper sees your normal checkout, so you can verify a rule on your live store safely.
Yes. A rule can hold multiple conditions, and you choose whether all of them must match or any one of them is enough. There are 29 conditions covering cart, customer, products, address, Shopify Markets, shipping selection and time of day.
Yes. A checkout validation stops the order from being completed and displays a message you write. You choose which of the 13 checkout fields the message appears under, so the buyer sees it next to the field that caused the problem.
You can discount shipping by a percentage, by a fixed amount, or set a flat rate. Discounts can apply automatically or require a discount code, can be scheduled with start and end dates, and can be limited by usage or to one use per customer.
The free plan lets you create one payment customization, one delivery customization, one validation and one shipping discount, with access to all 29 conditions. The Pro plan is $7.90 per month or $79 per year and raises the limit to five rules of each type, with a 7-day free trial and a 30-day money-back guarantee.
Install free, chat with AI, pick a template and watch it work on your own store. Nothing changes for your buyers until you say so.
